Normal Operation and Fault Conditions
An external antenna connected to the Tire Pressure Monitor Module (TPM) receives a signal from the Intelligent Access (IA) key 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 with a reduction in the range of operation.
