- Check DOOR LOCK and ROOM fuses located in interior fuse panel. If fuses are okay, reinstall fuses and go to step 5). If fuses are blown, go to next step.
- Replace blown fuse(s). Turn ignition on and inspect fuses. If DOOR LOCK fuse fails again, go to next step. If ROOM fuse fails again, go to step 4). If fuses do not fail, go to step 5).
- Disconnect door lock relay. See DOOR LOCK RELAY under REMOVAL & INSTALLATION. Measure resistance between ground and DOOR LOCK fuse socket top terminal (White/Green wire). If resistance is less than 5 ohms, repair short to ground in White/Green wire. See WIRING DIAGRAM . If resistance is not less than 5 ohms, go to step 5).
- Disconnect RAP module connectors. See CONTROL MODULE under REMOVAL & INSTALLATION. Measure resistance between ground and ROOM fuse socket top terminal (Blue/Red wire). If resistance is less than 5 ohms, repair short to ground in Blue/Red wire. See WIRING DIAGRAM . If resistance is not less than 5 ohms, go to next step.
- Disconnect door lock relay. See DOOR LOCK RELAY under REMOVAL & INSTALLATION. Measure resistance between ground and door lock relay connector terminal No. 5 (White/Green wire). See Fig 1 . If voltage is greater than 10 volts, reconnect door lock relay and go to next step. If voltage is less than 10 volts, repair open in White/Green wire. See WIRING DIAGRAM .
- Disconnect RAP module connectors C1 and C2. See CONTROL MODULE under REMOVAL & INSTALLATION. Measure voltage between ground and RAP module connector C1, terminal No. 25 (Blue/Black wire). See Fig 2 . Measure voltage between ground and RAP module connector C2, ter minal No. 12 (Blue/Red wire). See Fig 3 . If both voltages are greater than 10 volts, reconnect RAP module connectors and go to next step. If voltages are less than 10 volts, repair wire in question. See WIRING DIAGRAM .
