Circuit/System Testing
- Ignition OFF, disconnect the harness connectors at the appropriate module.
- Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 ohms between the following ground circuit terminals and ground:
- Terminal 4 (TDM)
- Terminal 31 (SDM)
- Terminal A6 (IPC)
- Terminal 2 X1 (Radio U85)
- Terminal A12 X1 (Radio U26)
- Terminal 6 X1 (PPS)
- Terminal 12 X1 (BCM)
- Terminal 13 X2 (BCM)
- Terminal E12 X4 (BCM)
- Terminal 25 X1 (FTC)
- Terminal 27 X1 (FTC)
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Verify that a test lamp illuminates between the following B+ circuit terminals and ground:
- Terminal 1 (SDM)
- Terminal 2 (TDM)
- Terminal B5 (IPC)
- Terminal 1 X1 (PPS, Radio U85)
- Terminal B1 X1 (Radio U26)
- Terminal 24 X1 (FTC)
- Terminal 26 X1 (FTC)
- Terminal D12 X3 (BCM)
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- If all circuits test normal, replace the appropriate module.
WARNING:
Refer to SIR Warning
, if DTC B1325 is set in the SDM.
