Safety Connect System

CELLULAR COMMUNICATION: SAFETY CONNECT SYSTEM: B15C0,B15C1: Short in GPS Antenna
B15C1 - Open in GPS Antenna

DESCRIPTION

This DTC is set when the DCM (Telematics Transceiver) detects an open or a short in the telephone and GPS antenna circuit. The DCM (Telematics Transceiver) receives 1574.42 - 1576.42 MHz radio frequency signals from satellites through the telephone and GPS antenna assembly. The cable is a 50 Ohms coaxial cable.

OK -- Continue to next step.

3. INSPECT TELEPHONE AND GPS ANTENNA ASSEMBLY

(a) Replace the telephone and GPS antenna assembly with a normal one and check if the same problem occurs again Removal.

OK:

The system returns to normal.

NG -- REPLACE DCM (TELEMATICS TRANSCEIVER)

OK -- END

4. REPLACE DCM (TELEMATICS TRANSCEIVER)

(a) Replace the DCM (Telematics Transceiver) Removal.

NOTICE:
* The ignition switch must be off.
* Do not swap the DCM (Telematics Transceiver) with one from another vehicle.

NEXT -- PERFORM DCM ACTIVATION DCM Activation
