Air Bag Indicator Light Test
NOTE:
For additional indicator diagnosis, see SYMPTOM IDENTIFICATION
table under SELF-DIAGNOSTIC SYSTEM.
- If AIR BAG warning light illuminates for 12 seconds or more, or stays on all the time, a system malfunction is present and trouble code will be stored. For air bag system testing procedures, see AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS.
- If air bag indicator light does not illuminate when ignition is on, replace air bag indicator bulb and retest. If air bag indicator light still does not illuminate, perform INSTRUMENT CLUSTER PRELIMINARY DIAGNOSIS .
- If after performing preliminary diagnosis and actuator test, air bag indicator light and instrument cluster circuitry is okay, diagnosis of air bag system and Programmable Communication Interface (PCI) data bus should be performed.
- For air bag system testing procedures, see DIAGNOSIS & TESTING in AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS. For PCI data bus testing, check for opens and shorts in PCI data bus circuits. See BODY CONTROL MODULES - WRANGLER article.
