Diagnostic Procedure

  1. Turn ignition on while observing AIR BAG warning light. If AIR BAG warning light flashes 7 times, system is okay. If AIR BAG warning light does not flash 7 times, go to next step.
  2. Turn ignition off and remove key. Connect scan tool to Data Link Connector (DLC), located under driver-side instrument panel. If DTCs are displayed on scan tool, diagnose and repair appropriate DTCs. If SIR DTCs are not displayed on scan tool, go to next step.
  3. Remove and inspect fuse F1 from instrument panel fuse box. If fuse is blown, go to next step. If fuse is not blown, go to step  5.
  4. Replace fuse F1 and retest system.
  5. Disconnect connector C207. See Fig 1. Check for a short to ground in Pink wire between fuse F1 and terminal No. 1 of connector C207. See Fig 2. If a short to ground is not found, go to next step. If a short to ground is found, go to step  12.
  6. Disconnect SDM connector. See SENSING & DIAGNOSTIC MODULE (SDM)  under REMOVAL & INSTALLATION. Check Pink wire between terminal No. 1 of connector C207 and SDM connector terminal No. 26 for a short to ground. See Fig 3. If a short to ground is not found, go to next step. If a short to ground is found, go to step  12.
  7. Measure continuity between ground and Data Link Connector (DLC) ground terminal. See WIRING DIAGRAMS . If continuity exists, go to next step. If continuity does not exist, go to step  12.
  8. Turn ignition on. Measure voltage at cigarette lighter. If voltage is 11-14 volts, go to step  10. If voltage is not 11-14 volts, go to next step.
  9. Repair wiring to cigarette lighter. Go to SIR DIAGNOSTIC SYSTEM CHECK .
  10. Inspect Light Blue wire between terminal No. 4 of connector C207 and terminal No. 13 of DLC for an open or short. See Fig 4. If a short or open is found, go to step  12. If a short or open is not found, go to next step.
  11. Inspect Light Blue wire between terminal No. 4 of connector C207 and terminal No. 54 of SDM connector. If a short or open is found, go to next step. If an open or short is not found, go to step  13.
  12. Repair wiring harness. See WIRE REPAIR .
  13. Replace SDM. Go to SIR DIAGNOSTIC SYSTEM CHECK .
