The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customer's may bring in their vehicle with a "Service Tire Monitor" message on the Drivers Information Center. Aftermarket wheels installed without the sensors will activate the "Service Tire Monitor" warning and will stay on until the sensors are installed. Even if the sensors are installed in aftermarket wheels they may not mount in the correct OEM orientation and still turn on the "Service Tire Monitor" message.
Recommendation/Instructions:
Before starting regular diagnosis, verify that the vehicle is equipped with GM factory or GM accessory wheels and tires. The wheels and tires should be the correct year and size that the vehicle was built with. If the vehicle is modified with aftermarket wheels and tires, do not perform any additional work until the factory wheels and tires are installed and the same concern can be duplicated for what the customer brought the vehicle in for.
Please make sure the customer's vehicle is equipped with the Factory wheels or GM accessory wheels before contacting the Technical Assistance Center
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
