DTC B1D55-11: Antenna #2 - Circuit short to ground: Action
NOTE:
Caution:
Only on vehicles with secure tracker feature installed
Failure to do so may result in any warranty claim being rejected
- The Telematics Control Unit Module (TCU) must be placed into service mode before proceeding
- Service mode disables all alert triggers except movement alert, the TCU can be put into service mode in 2 ways:
- Call Centre - Owner calls and requests that the vehicle be put in service mode
- Mobile App - Owner enables service mode
- If the TCU is not set into service mode, then communication to and from the TCU may be lost, which may prevent the vehicle starting
Failure to do so may result in any warranty claim being rejected
- To inspect for a permanent or intermittent fault, using the Jaguar Land Rover approved diagnostic equipment perform the diagnostic routine - On Demand Self Test (0x0202)
- If the fault is permanent, refer to the electrical circuit diagrams and inspect the GSM antenna circuit for short circuit to ground. Repair the wiring harness as necessary
- If the fault is intermittent, refer to the electrical circuit diagrams and test the GSM antenna circuit for short circuit to antenna shield/screen. Using a multimeter measure the circuit resistance between the GSM antenna cable central pin and the shield/screen at the antenna connector, the nominal resistance of the GSM antenna circuit will be approximately 10, 000 Ohms. Then apply pressure to the GSM antenna cable and manipulate the cable at the base of the GSM antenna to test for internal circuit failure. If the circuit resistance is reduced as the cable is manipulated an internal cable failure is confirmed. Replace the GSM antenna as necessary
