DTC 71: Passenger Side Impact Air Bag Module Short Circuit

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.
  1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . If DTC 34 is retrieved, go to next step. If DTC 34 is not retrieved, go to step  3.
  2. Inspect ECU SRS connector C-114. See Figure. If connector is not connected properly, connect properly and go to step  7. If connector is connected properly, go to next step.
  3. Disconnect negative battery cable. Disconnect SRS ECU connector C-114 and passenger side impact air bag module connector D-36. Reconnect both connectors. Connect negative battery cable. Using scan tool erase, then retrieve DTC's. If DTC 71 is retrieved, go to next step. If DTC 71 is not retrieved, system is normal at this time.
  4. Disconnect passenger side impact air bag module connector D-36. 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 71 is retrieved, go to next step. If DTC 71 is not retrieved, replace passenger side impact air bag module. See SIDE IMPACT AIR BAG MODULE  under REMOVAL & INSTALLATION. Go to step  7.
  5. Disconnect SRS ECU connector C-114 and passenger side impact air bag module connector D-36. Insert a cable tie or similar insulator between terminals No. 23 (Yellow/Black wire) and 24 (Yellow wire) of SRS ECU connector to release shorting bar. Check for continuity between terminals No. 23 and 24. If continuity exists between terminals, replace wire harness between SRS ECU and passenger side impact air bag module. Go to next step. If continuity does not exist, erase, then retrieve DTC's. If DTC 71 is retrieved, replace SRS ECU. See SRS ELECTRONIC CONTROL UNIT (SRS ECU)  under REMOVAL & INSTALLATION. Go to step  7.
  6. Check continuity of Yellow/Black wire and Yellow wire between SRS ECU connector C-114, terminals No. 23 and 24 and passenger side impact air bag module connector D-36, terminals No. 1 and 2. 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 passenger side impact air bag module. Go to next step.
  7. Reconnect all SRS components. Activate air bag system. Using scan tool retrieve DTC's. If DTC 71 is retrieved, go to step  1. If DTC 71 is not retrieved, system is normal at this time. Intermittent condition may exist.
