DTC 81: Driver 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. Go to step  6. If connector is connected properly, go to next step.
  3. Disconnect negative battery cable. Disconnect SRS ECU connector C-114 and driver side impact air bag module connector D-07. Reconnect both connectors. Connect negative battery cable. Using scan tool erase, then check for DTC's. If DTC 81 is retrieved, go to next step. If DTC 81 is not retrieved, system is normal at this time.
  4. Disconnect driver side impact air bag module connector D-07. Connect Load Resistor (MB991865) to Load Resistor Harness (MB991866). Connect load resistor harness to connector D-07 by backprobing connector. Connect negative battery cable. Using scan tool erase, then retrieve DTC's. If DTC 81 is retrieved, go to next step. If DTC 81 is not retrieved, replace driver side impact air bag module. See SIDE IMPACT AIR BAG MODULE  under REMOVAL & INSTALLATION. Go to step  6.
  5. Disconnect SRS ECU connector C-114 and driver side impact air bag module connector D-07. Insert a cable tie or similar insulator between terminals No. 21 (Yellow/Green wire) and 22 (Yellow/Red wire) of SRS ECU connector to release shorting bar. See Figure. Check for continuity between terminals No. 21 and 22. If continuity is found, replace wire harness between SRS ECU and driver side air bag module. Go to next step. If continuity is not found, erase, then retrieve DTC's. If DTC 81 is retrieved, replace SRS ECU. See SRS ELECTRONIC CONTROL UNIT (SRS ECU)  under REMOVAL & INSTALLATION. Go to next step.
  6. Reconnect all SRS components. Activate air bag system. Using scan tool retrieve DTC's. If DTC 81 is retrieved, go to step  1. If DTC 81 is not retrieved, system is normal at this time. Intermittent condition may exist.
