: 2002 DTS seat massages all the time

09-21-10, 05:19 AM
Upon starting the engine, the RF seat massager kicks in for some reason. This car has U codes (computer network) in the system, causing the check engine light to be on most of the time.

Could this computer network type issue be contributing to the seat massager coming on with engine startup?

Weird situation: U codes will not normally set a SES light - only P codes.

Use your car's built in code reader to pull the DTC's and post them here, with definitions. Note whether each code is Current or History.

OK will do. I did have one list from months ago, but tossed it. I'll get a current list together. Thanks
