Diagnostic Fault Information
Circuit/System Description
The radio generates the audible warning through the left speaker. The radio receives audible warning requests via the serial data circuit from the instrument panel cluster (IPC), the body control module (BCM) or the remote control door lock receiver (RCDLR).

Circuit/System Verification
Important: Before performing this diagnostics, make sure no indicators are illuminated after the IPC performs a lamp test. If any indicators are illuminated after the bulb test, perform the indicator diagnostics before this diagnostics.
1. Ignition ON, headlamp switch OFF, verify the scan tool Headlamp Switch parameter is Inactive.
• If not Inactive, refer to Headlamps Malfunction Headlamps Malfunction.
2. Ignition ON, park lamp switch OFF, verify the scan tool Park Lamps Switch parameter is Inactive.
• If not Inactive refer to Park, License, and/or Tail Lamps Malfunction (North America) Park, License, and/or Tail Lamps Malfunction (North America)Park, License, and/or Tail Lamps Malfunction (European) Park, License, and/or Tail Lamps Malfunction (European).
3. Ignition ON, doors closed, verify the scan tool All Door Lock Command is On.
• If not On, refer to Courtesy Lamps Malfunction Courtesy Lamps Malfunction.
4. Ignition ON, radio ON, adjust the radio balance and fade to the left front speaker.
• If the speaker does not operate properly, refer to Speaker Malfunction Speaker Malfunction.
5. Verify that the Key In Ignition Status parameter is Key In when the key is in the ignition and Key Out when the key is out of the ignition.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the key in ignition switch.
2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
• If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the power mode circuit fuse is open, test the signal circuit terminal listed below for a short to ground:
* Terminal 4 without UHA/UHF
* Terminal 5 with UHA/UHF
3. Verify the scan tool Key In Ignition Status parameter is Key Out.
• If not the specified value, test the signal circuit terminal listed below for a short to voltage. If the circuit tests normal, replace the BCM or the RCDLR.
* Terminal 4 without UHA/UHF
* Terminal 5 with UHA/UHF
4. Install a 3A fused jumper wire between the signal circuit terminal listed below and the B+ circuit terminal 2. Verify the scan tool Key in Ignition Status parameter is Key In.
* Terminal 4 without UHA/UHF
* Terminal 5 with UHA/UHF
• If not the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the BCM or the RCDLR.
5. If all circuits test normal, test or replace the ignition switch.
