Safety Connect System
CELLULAR COMMUNICATION: SAFETY CONNECT SYSTEM: B15C0,B15C1: Short in GPS Antenna
B15C0 - 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 signal from satellites through the telephone and GPS antenna assembly. The cable is a 50 Ohms coaxial cable.

Refer to "PARTS LOCATION" for the installation location of telephone and GPS antenna cord Safety Connect System.
INSPECTION PROCEDURE
PROCEDURE
1. CHECK DTC
(a) Turn the engine switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the engine switch on (IG) and wait for 10 seconds.
(d) Turn the Techstream on.
(e) Perform "HEALTH CHECK" and check for current DTCs Health Check.
Result:
B -- CHECK FOR INTERMITTENT PROBLEMS How To Proceed With Troubleshooting
A -- Continue to next step.
2. INSPECT TELEPHONE AND GPS ANTENNA CORDS (INSTRUMENT PANEL WIRE)
(a) Disconnect the instrument panel wire (antenna cord sub-assembly) connector from the DCM (Telematics Transceiver).
(b) Disconnect the instrument panel wire (antenna cord sub-assembly) connector from the telephone and GPS antenna cord (antenna cord sub-assembly).
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

NG -- REPLACE INSTRUMENT PANEL WIRE (ANTENNA CORD SUB-ASSEMBLY)
OK -- Continue to next step.
3. INSPECT TELEPHONE AND GPS ANTENNA CORDS (ANTENNA CORD SUB-ASSEMBLY)
(a) Disconnect the telephone and GPS antenna cord (antenna cord sub-assembly) connector from the telephone and GPS antenna assembly.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

Text in Illustration:
NG -- REPLACE TELEPHONE AND GPS ANTENNA CORD (ANTENNA CORD SUB-ASSEMBLY)
OK -- Continue to next step.
4. REPLACE 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
5. REPLACE DCM (TELEMATICS TRANSCEIVER)
(a) Replace the DCM (Telematics Transceiver) Removal.
NOTICE:
* The engine switch must be off.
* Do not swap the DCM (Telematics Transceiver) with one from another vehicle.
