WARNING: This page is about a different car, the 2003 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
- Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Disconnect negative battery cable. Disconnect passenger side impact air bag module connector D-36. See Figure. Connect Load Resistor (MB991865) to Load Resistor Harness (MB991866). Connect load resistor harness to connector D-36 by backprobing connector. Connect negative battery cable. Using scan tool erase, then retrieve DTC's. If DTC 72 is retrieved, go to next step. If DTC 72 is not retrieved, replace passenger side impact air bag module. See SIDE IMPACT AIR BAG MODULE under REMOVAL & INSTALLATION. Go to next step.
- Disconnect SRS ECU connector C-114 and passenger side impact air bag module connector D-36. Check Yellow/Black wire between SRS ECU connector C-114, terminal No. 23 and side impact connector D-36, terminal No. 2 and Yellow wire between SRS ECU connector C-114, terminal No. 24 and side impact connector D-36, terminal No. 1 for continuity. If continuity exists in both wires, go to next step. If continuity does not exist in both wires, replace wire harness between SRS ECU and side impact air bag module. Go to next step.
- Reconnect all SRS components. Activate air bag system. Using scan tool retrieve DTC's. If DTC 72 is retrieved, go to step 1. If DTC 72 is not retrieved, system is normal at this time. Intermittent condition may exist.
