Test F: Air Suspension Control Module Does Not Respond To NGS Tester
- Turn ignition switch to LOCK position. Disconnect Air Suspension Control (ARC) module Gray 16-pin harness connector C2000. See Figure. Inspect ARC module and harness connector for physical damage, bent terminals or corrosion. If connector is okay, go to next step. If connector is damaged, repair connector as necessary and recheck system operation.
- Measure resistance of Light Blue/White wire between ARC module harness connector C2000 terminal No. 29 and Data Link Connector (DLC) terminal No. 7. See Figure and Fig 1
. If resistance is less than 5 ohms, replace ARC module and recheck system operation. If resistance is 5 ohms or more, repair open in Light Blue/White wire between ARC module and DLC. Recheck system operation.
