Test Notes

Normal Operation
The air bag Electronic Crash Sensor (ECS) module will communicate the system fault codes through the New Generation Star (NGS) tester, using the Data Link Connector (DLC). If the NGS Tester displays "NO COMMUNICATION" when retrieving continuous DTCs, use this pinpoint test to troubleshoot the system.

Possible Causes
- Damaged wiring on ignition Circuit 298 (P/O).
- Damaged wiring on Circuit 70 (LB/W).
- Poor module ground.
- NGS Tester damaged.
- Low battery voltage condition.
