Fellow Cruiser-heads,

I'm having a random non-starting issue, in which the immobilizer light keeps blinking AND the VSC OFF and other VSC lights remain on after all the other lights turn off.

Quick background: it's 2001 LC I just bought. It has 127k and is a super-clean, fully stock, always garaged rig (that I bought for my wife) ...I drive an fjz80 w 235k and have never had a serious issue. I talked my wife OUT of a minivan and INTO the 100, and now it is randomly stranding us and our kids at various locations.

I know from other threads on here that replacing the EFI fuse is 1st order of business. I did this yesterday, and it did not solve the issue....but 30 minutes later the rig started right up.

I then drove to my office. Parked it for 2 hours. And it wouldn't start again (immobilizer blinking + VSC lights on after all other lights turn off). I called a tow truck. By the time the tow truck arrived, it started, so I drove it to the shop and parked it there.

This morning at the shop, it started right up...no lights, no codes.

I have read all the Immobilizer threads and will tell my mechanic to put new EFI and stereo fuses in it (it does have an aftermarket radio w/backup camera that I suspect to be involved).

I'm wondering though DOES ANYONE HAVE ANY EXPERIENCE WITH THE VSC LIGHTS being connected to the non-starting and immobilizer.

data:
-when not starting all accessories work fine, engine cranks, all lights turn off except VSC lights and battery light (we have already replaced battery cable, and battery gauge shows strong battery)

-when running, both VSC lights will randomly come on occasionally, sometimes for 30 seconds to a minute, then turn back off.

Any advice would be much appreciated. I know once I get this resolved the 100 will be a great vehicle for my wife and kids, but I've got a bit of egg on my face presently because I bragged to her about how it would never let her down.
 
I have very similar issue. Why no responces here?

My two VSC lights came on. I tried to clear codes (as detailed in another thread of earlir today), could not seem to exit diagnostic mode as now VSC TRACK and ABS lights were flashing. Decided to give up for night and find both key fobs do not lock or unlock, and the alarm arming front lights that flash when arming stayed on - permanently - I needed disconnect the battery.
 
UPDATE: Removing and cleaning the EFI main relay, oiling locks and disconnecting the battery over night reset my immobilizer and my keys now work fine. But I still have thoses two lights on that may be a seperate issue.

I have for the VSC lights a code 47 (open diff lock circuit). What codes do you have? Have you reset you yaw and deceleration? I did but it did not help me as I did not have a code 36/39. You must pull the codes and post them.
 
I’m having the same issue. Did anyone find a solution to this?
If you're referring to the EFI/immobilizer issue, these threads should help:
