DTC B15DD-13: Digital Audio Band Antenna 2 - Circuit open: Action
- Check the digital audio band radio is working by searching for any digital audio band radio stations and checking if the digital audio band source is active on the screen. If the digital audio band radio is working go to step 10, if not go to step 2
- 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 3, if the DTC is no longer set go to step 10
- Refer to the electrical circuit diagrams and disconnect the digital audio band #2 antenna cable from the digital audio band #2 antenna
- Measure the voltage between pin 1 of the digital audio band #2 antenna cable and a local ground connection on the vehicle
- If the voltage is greater than 9 volts, go to step 8, if not go to step 6
- Disconnect the digital audio band antenna cable from the front infotainment control module. Measure the resistance between pin 4 of the front infotainment control module connector harness side and pin 1 of the digital audio band #2 antenna cable connector harness side
- If the resistance is greater than 1Ω, replace the cable and go to step 2, if not go to step 9
- Reconnect the digital audio band #2 antenna cable back to the digital audio band #2 antenna and the front infotainment control module. Perform routine - On Demand Self Test (0x0202). If the fault persists, install a new digital audio band #2 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 2. If no software update is available go to step 10
- Check for other related Diagnostic Trouble Code(s) and refer to the relevant DTC index
