  1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Disable air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM . Inspect fuse No. 2 in driver-side junction block, located on left side of instrument panel. If fuse is okay, go to next step. If fuse is not okay, go to step  4.
  2. Disconnect negative battery cable. Disconnect SRS ECU connector C-115. See Figure. Connect negative battery cable. Turn ignition on. Measure voltage between ground and SRS ECU connector C-115, terminal No. 16 (Black/Yellow wire). See Figure. If voltage is less than 9 volts, go to next step. If voltage is 9 volts or more, erase DTC's using scan tool then check for DTC's. If DTC 41 is retrieved, replace SRS ECU. See SRS ELECTRONIC CONTROL UNIT (SRS ECU)  under REMOVAL & INSTALLATION. Go to step  10.
  3. Check wire harness between SRS ECU connector C-115, terminal No. 16 and ignition switch connector C-303, terminal No. 2, including connectors C-203 and C-206. See Figure. See WIRING DIAGRAMS . If wire harness or connectors are damaged, replace wire harness. Go to step  10. If wire harness and connectors are okay, go to step  10.
  4. Replace fuse. Turn ignition on for at least one minute, then off. Inspect fuse. If fuse is okay, go to step  10. If fuse is not okay, go to next step.
  5. Disconnect connector C-205 from junction block. See Figure. Check for continuity between ground and connector C-205, terminal No. 24 (Black/Yellow wire). If continuity exists, go to next step. If continuity does not exist, go to step  8.
  6. Check for continuity between ground and terminal No. 25 (Black/White wire) of connector C-205. If continuity does not exist, check other circuits which are associated with fuse No. 2. See WIRING DIAGRAMS . If continuity does not exist, go to next step.
  7. Check wire harness between connector C-205, terminal No. 25 and combination meter connector C-04, terminal No 42. for a short to ground. If wire harness is okay, go to step  10. If wire harness is not okay, repair wire harness. Go to step  10.
  8. Disconnect SRS ECU connector C-115. Check for continuity between SRS ECU connector C-115, terminal No. 16 (Black/Yellow wire) and ground. If continuity exists, go to next step. If continuity does not exist, erase, the retrieve DTC's using scan tool. If DTC 41 is retrieved, replace SRS ECU. See SRS ELECTRONIC CONTROL UNIT (SRS ECU)  under REMOVAL & INSTALLATION. Go to step  10.
  9. Check Black/Yellow wire between SRS ECU connector C-115, terminal No. 16 and junction block connector C-205, terminal No. 24 for damage or an open or short circuit. If wire is okay, go to next step. If wire is not okay, replace wire harness and go to next step.
  10. Reconnect all SRS components. Activate air bag system. Using scan tool retrieve DTC's. If DTC 41 is retrieved, go to step  1. If DTC 41 is not retrieved, system is normal at this time. Intermittent condition may exist.
