TELEMATICS  TELEMATICS SYSTEM(for ERA-GLONASS)  B157011  Indicator (Red) Circuit Short to Ground  B157013  Indicator (Red) Circuit Open  


DESCRIPTION

This DTC is stored when the telematics transceiver detects an open or short in the manual (SOS) switch red indicator circuit of the manual (SOS) switch.

The manual (SOS) switch red indicator illuminates for 5 seconds and goes off when the ignition switch is turned to ON.

If a malfunction in the telematics system is detected, the manual (SOS) switch red indicator will blink. However, the manual (SOS) switch red indicator may not illuminate when this DTC is stored.

DTC No. Detection Item DTC Detection Condition Trouble Area
