Traction control and ABS lights

I've been getting the TCS and ABS lights to come on sporadically, now TCS is on all the time. I had the ABS light on today too.

The codes I've been getting regularly are C1284 and C1285. Today I also had P1689 and C1276.

Is there a common ground for these?

Any help is appreciated.

Thanks.

Some of these codes relate to the solenoid circuits in the EBCM and BPMV. Recommend checking the following: #53 fuse in the underhood electrical center; check the connection between the EBCM and BPMV (requires removal of the EBCM from the BPMV) - there may be leaking brake fluid that touched the circuitry; check the grounds - especially G108 under the battery; and if the EBCM requires repair - send it to www.absfixer.com Hope this helps.

C1284 and 1285 indicate you have a problem with the lateral acceleration sensor which is located near the tunnel under the passenger seat. What year car do you have? For pre 01 cars the diagnostics are a little different than the 01 and newer cars. I haven't read them in detail so they could be the same thing just written differently. C1276 and P1689 indicate there is a problem with the delivered torque signal from the PCM to the EBCM. This could be due to a poor ground at G108 or at the PCM. This is not a problem that ABSfixer can fix. All he does is replace the relay that causes the C1214 code.

Send me a PM with the year of your car and I can send you a bunch of information to get you started.
