DTC |
B157113 |
Indicator (Green) Circuit Open |
DESCRIPTION
This DTC is set when the DCM (telematics transceiver) detects an open or short in the manual (SOS) switch green indicator circuit of the manual (SOS) switch. The manual (SOS) switch green indicator illuminates after the power switch is turned on (IG).
If the safety connect system is not active, the manual (SOS) switch green indicator will turn off.
If the safety connect system is active, the manual (SOS) switch green indicator will blink while communicating with the call center.
