TELEMATICS  TELEMATICS SYSTEM  B157111  Indicator (Green) Circuit Short to Ground  B157113  Indicator (Green) Circuit Open  


DESCRIPTION

This DTC is stored when the telematics transceiver detects an open or short in the emergency call switch indicator (green) circuit of the emergency call switch.

The emergency call switch indicator (green) illuminates for 5 seconds after the ignition switch is turned to ON.

If the telematics system is not active, the emergency call switch indicator (green) will turn off.

If the telematics system is active, the emergency call switch indicator (green) will blink while communicating with the call center.
