Wobbling mirror fix.

While playing with radio I noticed the mirror wobbling. So I tighten it up. I often see people tightening the large screw seen from bottom. But usually it's the inner small screws that need tightening. It's very import to use the right size screwdriver for each size, as those little ones get damaged easy.

B1153 DTC. I had one last DTC to deal with; "seat position sensor assembly" wire repair.

The airbag SRS dash light would not go off. I checked DTC's and found a B1153. In looking at my original long list of DTC this one was there. But was it there because some other issue, or was it the switch's wire all along, IDK. But for some reason the red wire was broken away from switch housing that plugs into seat position sensor (driver side outer switch). In searching mud I see others have had this issue as well, and mostly this red wire. The wires have very little slack and will move a little each time one sit in the driver seat. I suppose it just wire loosen over time and eventional breaks away from terminal. My Toyota Dealer keeps many terminal with pigtail on hand, the housing is special order. I decide to see if soldier would do the trick, it did. It may have been better to just replace both wire terminals adding some length, but only time will tell. So if air bag LIGHT COMES BACK ON, this is first place to look.

Like all wire housing I've come across, a plug must be pulled from center. This releases lock of wire terminals from within. The trick is then seeing how it's locked. In this case there is a small plastic catch half way in, that I used a needle to hold out as I pushed terminal through (out the back side).

After soldering, I plugged housing it back into Seat Position Sensor.

Each time we sit in the driver seat, the cushion springs push down. This releases tension on the wires at first. If seat spring pushed down further by sitting on side of seat or more weight added, it may take up slack again pulling on wire. In any case each time we sit the wire moves. I call this a design issues.

Note: When removing seat wires, disconnect battery 90 seconds before hand. After i fix wire and installed seat, I zero calibrate the front seats in tech stream.

No more DTC..... hurray.

Oh but I do see I'll one tire pressure sensor not reading, which I tracked to RF tire. I'll have tire shop scan this to see if battery is dying or dead. I'm not getting a dash light so may be intermittent or just not registered. IDK, as I don't normally deal with these. I just look/inpest my tires, just as OM instructs.

AHC check up:

AHC reservoir is indicating about 12 hash marks from H to L.

Checked AHC pressures, while techstream hooked up and running. They looked great with:
Front Pressure Sensor at 6.8 and rear at 5.9 Mpa-g.

I'm sure the rear coil spring spacer I installed helped to rear, and will add to life of rear globes. But I've only 1/3 tank of gas, so I'll come back and check again then adjust heights (if needed) after topping tank.

I rechecked with full tank of gas:

Measurement at wheel wells held at:
LF 19"
RF 19 5/16"
rears 20"

 

[2001LC]

Coil spring spacer installed.
As noted in test drive post, I actually did this some time ago. While doing the rear bushing I installed two OME coil spring spacers totaling 15mm (10 & 5mm spacer) on each side.

Start by releasing rear links and lower end of shocks.

Greasing make assembly easier and reduce chance of rusting in.

I find it easier to compress DS spring coil, than to disconnect AHC high control or risk to much stretch on rear upper brake lines. This power build spring compressor set from Advance Auto, really worked well. The PS I just press down on rear axle as I hold DS of axle up with a jack. PS spring then just drops out, without use of spring compressor.

Factory installed a thin black rubber insulator which goes on top with spacer between that and coil spring. The the assembly (coil spring, spacers & insulator) fit around a large bump-stop.

 

[2001LC]

Stabilizer links and bushing installed, front & rears. Replacing these really makes a difference in the turns, More so at high speeds, as it reduces sway increasing stability.

Not waiting until stabilizer bar and brackets on LCA are worn out, keeps in new like condition ..SWEET!
Usually we wait until the links break, putting up with excessive sway in the turns. But then we see the stabilizer bars link mount holes worn out and link brackets on LCA worn through into metal.

 

[2001LC]

The bolts holding links and the bushing sometime rust in. So I add a little grease after cleaning as a PM.

I find it best to assemble both side loosely installing links and bushing. Then come back and torque to spec.

 

[2001LC]

Rear stabilizer links, spacer & bushings.

I use bolt as a tool to grease inside walls of spaces as a PM.

With rears, I torque links as I go.

After torquing link in bracket, I put in place up assembly torque bracket in place.

 

[2001LC]

Rear bar bushings & brackets are placed in loosely and torqued after complet assembly is in place.

Note: AHC rear bar rubber bushing are different size with AHC.

 

[Njck22]

For the bushings, you used the rubber grease, and then regular synthetic for the bolts right? Does the rubber grease seem to be that important? Worth the hefty(I'm assuming) price tag?

No grease is called for.

That said;

I used the rubber grease, because the collar was being difficult to press into the rubber bushing. I had purchased the grease from Toyota for ~$10 for brake calipers, and decided to give a try here.

I've been finding these collars worn out and bolts rusty on many rig (although, not this rig). So used the Red-N-tacky grease inside the collar and on bolt shaft as a lube to reduce wear as a PM against rust.

I also put some Red-N-Tacky on the brackets at points they contact frame as a rust PM. This again is a spot(s) I typically see rust.

I'd not seen that tool. The video I posted took it to a pinpoint on one wire of a coil

I'm thinking your right, that I pushed the coil over the edge. Fuel smell was during and after warm up before changing coil. I need to do some more smell test (cold & hot) now that I've replaced the one coil. But first impression of lower fuel smell was cold. It did have a very slight drone while sitting a light in D. I've not driven since coil replaced, so need to get out and do so more test drives.

SAI system? not sure what you referring to (brain not working today..LOL)?
With Snowy where we did replace all coils, no fuel smell cold or hot after. We did not do A/F or O2 sensors, but now feel/know we should have.

Some thoughts on TBK drone:

It does have new Denso spark plugs, but the TT may be sweet. Doubt it will effect drone.

TBK has not had fuel injector service off vehicle only on, at ~46K. Nor fuel pressure regulator (FPR) replaced. You wouldn't think it necessary with such low miles. But low miles could indicate long periods of sitting without engine started. IIRC correct Toyota history showed fairly consistent low mile driving. Which may have been daily or weekly trips (no way to know) it could have also sat month at a time. The reason I mention this is Chuck at FIS told me that needles in fuel injectors and FPR get rust spots. Bad fuel and/or sitting not running engine could cause moisture on needles to form and rust. That the fuel pressure regulator will act badly at certain temperatures ~ 98F. A sign of the FPR is going bad is MPG will vary.

Fuel dampening device we only look to see if opens (pops up). But @abuck99 recently mention to me, he's seeing post on issues with it.

Another area to be aware of that we hear more issues with in the 06, is fuel pump. This one acts ups ascending mountain passes in many cases, but pump test fine. See notes in Snowy thread and Toyota history reports on this. Where dealer chased for years a shutdown ascending up to Eisenhower tunnel. Finally they (Stevenson Toyota) replaced the fuel pump and it was never reported again.

Gas cap seal gets old so mileage makes little difference.
Fuel return line clips on engine cover DS rear. Check to make sure it's on. Not big deal but vibration has it's effects shaking up fuel.

I doubt it's your coils at ~60K or your A/F or O2's sensors, as they seem more mileage sensitive than age. Although I now have my first found coil issue and only acting up under load when hot. So it goes to show they can go at any mileage. And some have had CAT codes at very low miles that turn out to be O2's (rears).

I've had issue with bad fuel often, that changing gas station and a can of 44K corrected. So considered that as well.

One other issue I've become concern with is throttle body. If anything makes you think that could be issue, I've a couple of extras we could swap out to see what happens.

Thanks for the drone tips. I've been reading on it a bit so when I get some time I'll dig in.

SAI=Secondary Air Intake.

How are you liking the blue headlights? I put them in my GF's t4r and didn't like them. The light output seemed strong but somehow the light was not enough and I felt the blue uncomfortable to my eyes. YMMV of course as some really like them.

I've not driven at night with the new bulbs (Blue) yet, so I can't say.

No leaks so buttoning up by installing shielding.

I driven a few hundred miles and had idling more than and hour. Not good idea to let idle for prolonged periods, but no choice when working on some systems. After each drive or idling I inspect for leaks. All looks good!

 

[2001LC]

Skid plate rust PM and bottom radiator foam ("cooler pack") pad install.

The radiator has foam padding all the way around it. This is the bottom piece that fits between it and skid plate. It is the only one that I've found needs PM (replacing).

 

[2001LC]

Toyota support tells me the foam is a vibration damping device. IDK, my thinking is it helps divert airflow through radiator.This foam goes bad. When it does go bad, it soaks up moisture like a spunge. So inspecting every few years and replace once it doesn't repel water.

I found where those two extra bolt go, oil filter hatch..DUH.
No extra parts, nut, bolts, fasteners or clips....NICE
#1 and #2 undershields installed. Only missing the little oil hatch that goes in #2 shield, as it didn't have one. I may have one in a box somewhere I'm looking now. But these get misplaced most any time some shop changes oil.

Note: I've updated post #174 on page 9 with transmission fluid level check proceedure, as promised.

Which includes a TSB that gives us a lower ATF temperature to between 97 F and 115 F we must use when checking ATF level, this differs from the FSM spec of 115 F to 130 F.

Thank you @abuck99 for emailing the TSB.

Perfecting body paint.

Then I clay bar using same soap to lubricate. The new synthetic clay is sweet! It's fast and can be cleaned.

I had some stain from auto transport dripping fluid from vehicle stack above it. I really thought I'd gotten it all cleaned off last fall. But after clay bar, which really reveals, I found some staining remained in paint. Here and on hood.

I tried a typical aggressive clay to remove stain, nope. Then moving up the food chain all the way to Lacquer thinner, nope.

Finally after going from mildest to most aggressive shop cleaning supply, I removed the stains with 100 % fast Urethane.
