Diagnostic Strategies
DIAGNOSTICS PROCEDUREAIRBAG WARNING LIGHT STAYS ON AFTER 8 SECONDS.
1. Perform on-board diagnostic.
2. Are trouble codes 4,12,13, 22, 34, 41, 42 or 43 indicated?
Record trouble codes. If "YES" proceed to step 4). If "NO" proceed to step 3).
3. Proceed with diagnostics and repair according to trouble code indicated then perform step 15).
4. If codes 4, 22, 34, 42 are indicated, proceed to step 5).
If codes 4, 22, 34, 42 are not indicated, proceed to step 10).
5. If codes 12,13,41,43 are indicated, proceed to step 6). If codes 12,13, 41, 43 are not indicated, proceed to step 11).
6. Turn ignition switch "OFF", disconnect battery ground cable, and wait 20 seconds. Disconnect passenger side airbag module connector (AB9) to (AB10). Connect test harness C connector (1C) to (AB9).
Connect airbag resistor to test harness C connector (3C). Remove lower cover panel and connect test harness C connector (1C) to (AB8) with airbag resistor attached to test harness C connector (3C).
Connect battery ground cable and turn ignition switch "ON". Does airbag warning light go "OFF" after 8 seconds and remain off for more than 30 seconds?
See "NOTE".
If "YES" proceed to step 7).
If "NO" proceed to step 3).
7. Turn ignition switch "OFF", disconnect battery ground cable, and wait 20 seconds. Connect passenger side airbag module connector (AB9) to (AB10). Connect battery ground cable and turn ignition switch "ON". Does airbag warning light go "OFF" after 8 seconds and remain off for more than 30 seconds?
See "NOTE".
If "YES" proceed to step 8).
If "NO" proceed to step 13).
8. Turn ignition switch "OFF", disconnect battery ground cable, and wait 20 seconds. Connect connector (AB8) to (AB3). Remove driver side airbag module and connect test harness C connector (1C) to (AB7).
Connect airbag resistor to test harness C connector (3C). Connect battery ground cable and turn ignition switch "ON". Does airbag warning tight go "OFF" after 8 seconds and remain off for more than 30 seconds?
See "NOTE".
If "YES" proceed to step 9).
If "NO" proceed to step 14).
9. Turn ignition switch "OFF", disconnect battery ground cable, and wait 20 seconds. Replace with a new driver side airbag module. Proceed to step 15).
10. Turn ignition switch "OFF", disconnect battery ground cable, and wait 20 seconds. Remove lower cover panel and connect test harness C connector (1C) to (AB8) with airbag resistor attached to test harness C connector (3C).
Connect battery ground cable and turn ignition switch "ON". Does airbag warning light go "OFF" after 8 seconds and remain off for more than 30 seconds?
See "NOTE".
If "YES" proceed to step 8).
If "NO" proceed to step 3).
11. Turn ignition switch "OFF", disconnect battery ground cable, and wait 20 seconds. Disconnect passenger side airbag module connector (AB9) to, (AB10).
Connect test harness C connector (1C) to (AB9). Connect airbag resistor to test harness C connector (3C). Connect battery ground cable and turn ignition switch "ON". Does airbag warning light go "OFF" after 8 seconds and remain off for more than 30 seconds?
See "NOTE".
If "YES" proceed to step 12).
If "NO" proceed to step 3).
12. Turn ignition switch "OFF", disconnect battery ground cable, and wait 20 seconds. Replace with a new passenger side airbag module then proceed to step 15).
13. Turn ignition switch "OFF", disconnect battery ground cable and wait 20 seconds. Replace with a new passenger side airbag module then proceed to step 7).
14. Turn ignition switch "OFF", disconnect battery ground cable, and wait 20 seconds. Replace with a new combination switch, and install driver side airbag module. Connect battery ground cable and turn ignition switch "ON". Does airbag warning light go "OFF" after 8 seconds and remain off for more than 30 seconds?
See "NOTE".
If "YES" proceed to step 16).
If "NO" proceed to step 9).
15. Connect battery ground cable and turn ignition switch "ON".
Does airbag warning light go "OFF" after 8 seconds and remain off for more than 30 seconds?
See "NOTE".
If "YES" proceed to step 16).
If "NO" proceed to step 1).
16. Perform clear memory procedure.
If memory cannot be cleared, another trouble code exists. Return to step 1).
If memory can be cleared, proceed to step 17).
17. END
NOTE:
- Always remember to secure the green double locks before turning the ignition switch "ON".
- In some cases the airbag warning light will go "OFF" after 8 seconds but will turn "ON" again within 30 seconds. In this case continue diagnostics with the basic diagnostics procedures or trouble code procedures.
