ABS light on, error C1225/25, changing solenoid module possible? (6 Viewers)

[Knuttski]

Hi folk, first post here. Great forum, been following a long time and learnt a lot from this site!

Owner of a HDJ100 '98.
ABS light came on a while ago, ABS brakes not setting in when locking the brakes. Local Toyota shop checked everything (wires, sensors etc) and found nothing wrong except error code C1225/25.
From FSM: "Open or short circuit in hydraulic brake booster solenoid circuit
(SA1 circuit) Hydraulic brake booster"
Toyota think the fault is "somewhere" in the brake master assembly. Solution: new brake master assembly for almost $3000 (in Norway). (I also checked the resistance on the ABS sensors and got 1076 Ohm at front sensors and 1364 Ohm on rear sensors).

The brakes are working great, I really dont think there is need to do change that Cylinder (0449360320) in the brake master assembly... The motor for the pump and accumulator seems to be working ok: The pressure is always building up at ignition turned to on. This process takes 1 minute at most. I checked the voltage between the solenoid module and the motor (for the pump) and got 12 V when the pump set in. Seems right.

I'm wondering the fault can be found in the solenoid module. I believe the "SA1 circuit"-thing is to be found inside this secret black box... This part is not available from Toyota, but found a used one at Cruiserparts.net. They call it "Skid Controll Actuator 98-02":
ABS Skid Control Actuator 98-02 Used [47025-60041-U-R] - $350.00 : CruiserParts.net, Toyota Landcruiser Parts

Anyone had success in changing or fixing the solenoid module on this car? I opened the front cover and loosened the 3 small screws inside but everything is attached/glued together... I guess behind the solenoid valves there is a circuit board? It seems non-serviceable.

I searched the forum but cannot see anyone having serviced the solenoid module. As a reference here are some other members work on the Master brake assembly:

Motor/pump/cables failure:
ABS Modulator - (Master cylinder, Pump/Motor, Accumulator, Resivoir, Solenoid module)

Master cylinder rebuild:
Master Cylinder Rebuild - DIY

Any tips appreciated!

Welcome to hell

What was the solution to this issue?
I'm having the same code and my abs pump sounds like is overworking. Today I replaced the skid control computeroom with no luck.
I got a used one, does it need to be Flashed or reprogramed?

I'm no expert, but 1 min sounds long. I'd lean towards replacing pump and accumulator, and rebuild master cylinder while there, as preventive maintenance if for no other reason than to avoid a total failure.

Same issue...any progress on this?

I wanted to bring this back to the top for any updates. My truck is currently at a shop(OTRAMM - highly recommend) and I was told the SA1 Circuit has a short and needed to be replaced. I guess this is an expensive part as I was quoted $3000 for the repair.

I'm interested in replacing the SA1 Circuit but nothing else. Mainly trying to do this repair and not break the bank...I only paid $3000 for the truck itself.

Hi all, sorry for not giving you feedback. This is what I did:
Ordered a used ABS solenoid module (they called it skid control unit) from cruiserparts.net. 350$.
Installed it. The ABS light disappeared after start up! A great moment.
Took a test ride and hit the brakes - I could feel and hear the ABS working .
This is 3 years ago and the ABS is still working.

Hi. I have the same problem with a 1998 100 series in Costa Rica.

Some time ago the brake system stopped completely, I repaired it and it worked correctly for about 3 months, now I have that code but the car brakes well

Can you post a picture on where this unit is located?

It's on the side (or was that the bottom in my pic below??) of the brake MC.

Can anyone tell what the solution for this is I have the same code

Brakes ...... Overdue write-up.

First and foremost: Brakes should only be worked by those, with high level of mechanical abilities and experienced with brake systems. With the age of all 100 series today, in our aging fleet. Any issue, with brake master assembly. IMHO, best and safest course of action. Have the whole brake...
