Hello. My name is ***** ***** I will be assisting you today. Give me just a moment, please, to locate this information for you.

Expert:  Todd M replied 4 months ago.

Your fuse is the PCM fuse. It is located in the engine compartment fuse box.

Expert:  Todd M replied 4 months ago.

Let me check for a relay.

Expert:  Todd M replied 4 months ago.

There is no relay information for the PCM. The PCM and the ECM are one in the same, just different names.

I've checked the small fuse box located in the engine comp. and found no fuse labeled ECM or ECU. Is there another fuse box in that same area? My goal is to reset the ECM, to release the Traction Control Mode as the release button in the glove box does nothing.Thanks so much and looking forward to your reply.D. Hyland

If you look at this diagram, you will see ABS(10amp), PCM IGN(10amp), PCM BATT(10amp). These are your fuses for the PCM(which is also the ECU/ECM), and the ABS fuse controls the traction control.

I have sent location information for this fuse box. It is under the hood on the drivers side.

Expert:  Todd M replied 3 months ago.

If the fuses are good, and the issue isn't fixed, then you will likely have an issue with the brake control module.
