Pinpoint Test A: Air Bag Indicator Illuminated Continuously - ECS Module Disconnected or Inoperative

Normal Operation

NOTE: During normal operation the air bag indicator will be lit continuously for 6 seconds after the ignition switch is placed in the RUN position and after five cycles of a Lamp Fault Code (LFC) if a fault exists. Be sure to cycle the ignition switch and look for a 6 second indicator proveout without LFCs.

The air bag Electronic Crash Sensor (ECS) module will communicate Diagnostic Trouble Codes (DTCs) through the scan tool using the Data Link Connector (DLC). If the scan tool displays NO COMMUNICATION when retrieving continuous DTCs, use Pinpoint Test V to troubleshoot the system. Test V: No Communication With the ECS Module

Possible Causes

An air bag indicator that is illuminated continuously can be caused by one of the following:
- the battery or ignition circuit damaged.
- the ECS module disconnected from the vehicle harness.
- a loss of ECS module ground circuits.
- the ECS module inoperative.
- the scan tool damaged.
