An external antenna connected to the Tire Pressure Monitor Module (TPM) receives a signal from the Integrated Keyhead Transmitter (IKT) transmitter to enable activation of the remote start function from a distance of up to 100 meters (328 feet). If the external antenna fails, the remote start operates using the TPM internal antenna, with a reduction in the range of operation.
- DTC B1D55:01 (Antenna #2: General Electrical Failure) - this DTC is set if the vehicle is equipped with remote start but the system feedback circuit does not detect an external antenna.
This pinpoint test is intended to diagnose the following:
- External antenna
- External antenna lead
- TPM
