Has anyone had the following issue?

Problem:
ABS and Traction Control lights are lit up solid, Multi-Terrain light is flashing

Code Pulled (from Autonation South Austin Toyota):
C1425

Attempted Solutions (so far):
Tech replaced Stop Light Switch under dash
5/3: Tech found a short circuit in the driver's side rear brake light assembly, waiting to hear if this is the fix

Fix When the Autonation South Toyota Collision center replaced the tail light assembly they inadvertently stretched the harness to the tail light causing a small short in the circuit that was causing the ECU to be unhappy and throw the trouble codes and lights. The harness was replaced and the lights are now off.

Log of events so far:
4/19
Took 4Runner to Autonation South Austin Toyota for 70k service including oil change, tire rotation, brake fluid flush/fill, and fuel system cleaning.

4/20
Went to pick up truck and on a quick inspection discovered that the tech had not replaced all the bolts and fasteners on the front skid plate after doing the oil change. This left some suspicion on lack of attention to detail while servicing the 4Runner.

4/24
Picked up 4Runner early in the morning and everything seems fine, the missing fasteners had been replaced.

4/26
Started the 4Runner this morning and the ABS and Traction Control lights were on and the Multi-Terrain light was flashing.

Took truck back to Autonation South Austin Toyota, tech replaced the Stop Light Switch under the dash. Warning lights were off when truck was returned.

4/28
Same set of warning lights come on later that evening after putting the truck in reverse then switching to drive. I turned the truck off let it sit a minute and turned it back on, warning lights were off.

4/29
Start the truck in the morning, put truck in reverse and then into drive and warning lights come back on.

Took truck back to Autonation South Austin Toyota and the service manager had the tech pull the code: C1425, same code as before.

The service manager said they'd continue to look into it but being Saturday they were limited with staff but to expect a call back Monday.

5/1
Autonation South Austin Toyota had the truck all day but there no communication as to what they were working on or if they were even looking at the truck.

5/2
Left messages with two service advisors in the morning and have still not heard back with any updates.

Left message with the head service manager.

Late 5/1
Called again, had the receptionist find a service manager to talk to. They said based on what I told them regarding the rear brake light, they found a short in the drivers side tail lamp assembly that had been replaced by the Autonation South Toyota Collision Center. I am waiting to hear how long it will take to fix it.

5/3/
Picked up truck, warning lights were gone but now noticed a gap between the tail light assembly and the body that was not there before and a chip in the brand new paint near the tail light assembly. Took pictures with one of the Service Advisors and will speak with the GM about it tomorrow.

5/4
Met with Service Director and Body Shop manager, will be dropping truck off Monday to have tail light fixed and paint repaired. There seems to be a low level of empathy for the frustration they've caused.

Googling around it looks like you lost ground on ecu electrical or similar(I'm not an expert on auto stuff). I would check the code myself just to verify and look for loose wires, there are electrical diagrams out there if needed.

I would also find a different Toyota if you don't have luck. Their service is not up to Toyo standards and it just isn't worth your time or money to deal with them.

@ Panzerpatty

I hear ya. Has anyone in Austin had better experience with the other dealerships or service centers in town? If so who do you use and which service advisor should I speak with?

I just got through with the same batch of errors. Mine appears to be related to water intrusion or low voltage however. The lights were off on every startup, but came back after progressively longer driving trips. They've been off for a few trips now. I've found a few other threads on this related to water intrusion and the brake switch. I'm still looking around so I can be prepared if they come back.
