WARNING: This page is about a different car, the 2009 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
- The purpose of this diagnostic is to verify the ability of the CIM to pair to a Bluetooth ® device.
- Before performing this test, verify compatibility of the cellular phone(s) the customer is attempting to use with the vehicle. A vehicle and feature compatibility list will be provided via the GM Bluetooth ® website. Based on the cellular phone's service provider and the manufacturer's implementation of Bluetooth ®, not all phones support all available Bluetooth ® functionality.
- If the vehicle passes the following tests and a compatible device is being used, the concern may be due to a device malfunction or an incomplete/improper pairing attempt.
- The GM Bluetooth ® test tool 453-U260-000-R can also be used to verify the ability of the customers cellular phone(s) to pair with another device.
