Error code C1201

[Boneyone Member Find all posts View Profile Close Boneyone]

A mate connected his Launch scan tool recently and my vehicle is reporting C1201 Engine/EV Control System Malfunction as current. However, there are no dash lights to accompany it. A quick search indicated that it may be the Stability Control requiring a calibration. Has anyone carried out the Stability Control Zero Point Calibration described here https://ricksfreeautorepairadvice.com/c1201-toyota/

C1201 is an Engine Control System Malfunction (according to my info). Was code C1202 a typo as I can't find anything?

If a malfunction is detected in the engine control system, the ECM sends a malfunction signal to the skid control ECU. The skid control ECU stores this DTC and prohibits the following controls:

1. VSC
2. TRC
3. Downhill assist control
4. Crawl control
5. Multi-terrain select control

Sent you a PM.

Yes, my mistake, C1201 is the correct code. Early indications are there should be some form of warning light such as engine check or TRC or ESC off but I don’t have any warning lights active. I will hit the books and do some more research. I thought I had a memory of mention of the stability control zero point calibration.

A bit of research reveals there can be multiple reasons for the error code, one of them is if the spiral cable has been replaced and the steering cal & zero point cal aren’t done afterwards. I had the dealer replace the spiral cable about 18 months ago so I’m tipping they never did the extra tasks, especially as I have no warning lights.
