C1242 code
Hey guys, I have done a thorough search and found that this horse has been beaten just about dead, however nothing that I have found has provided me a solution. So far I have tried:
- Applied power directly to the BPMV to run it. It runs normally, so the motor itself seems fine.
- Measured 1.8 ohms on the ground circuit between pin G on the EBCM connector and the negative side of the battery (also, the connection pins looked fine, no corrosion, not bent, etc.), therefore this does not appear to be a grounding issue.
- Measured 12 volts on the power wire to the connector at the EBCM.
- After doing the above I cleared the DTC codes, only to have C1242 return within about a second or two.
I have seen that some have said that sending the EBCM to ABSFixer. If this would fix my issue, wouldn't I have a C1214 code?

I fixed the C1242 code, and it wasn't the relay. I replaced the relay and the issue did not go away, so I decided to do some more investigating and tracing circuits out with my multi-meter. I discovered at this time that 2 solders were broken on the PCB! After resoldering them and clearing the codes the lights went away, and I was able to turn traction control/active handling on/off, and also enable competitive driving mode. I have made a red rectangle around the 2 connections that I resoldered. For anyone else working out the same issue, I would recommend replacing the relay while you're in there, since it's a known point of failure.
thank you for posting your repair.
