DTC B119F-12: GPS Antenna - Circuit short to battery: Action
- Using the Jaguar Land Rover approved diagnostic equipment, perform routine - On Demand Self Test (0x0202) and read the Diagnostic Trouble Code(s). If the DTC is set go to step 2, if the DTC is no longer set go to step 9
- Refer to the electrical circuit diagrams and disconnect the global navigation satellite system antenna cable from the global navigation satellite system antenna
- Measure the voltage between pin 1 of the global navigation satellite system antenna cable and a local ground connection on the vehicle
- If the voltage is greater than 9 volts, go to step 5, if not go to step 7
- Disconnect the global navigation satellite system antenna cable from the front infotainment control module and repeat step 3 measurement
- If the voltage is greater than 9 volts, rectify the short circuit, replace the cable and go to step 1, if not go to step 8
- Reconnect the global navigation satellite system antenna cable back to the global navigation satellite system antenna and the front infotainment control module. Perform routine - On Demand Self Test (0x0202). If the fault persists, install a new global navigation satellite system antenna
- Check the front infotainment control module software release notes to see if a repair is available and update the front infotainment control module and repeat step 1. If no software update is available go to step 9
