Test E: Air Suspension Control Module Does Not Respond To NGS Tester
NOTE:
After making any repair, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM.
- Turn ignition switch to LOCK position. Air suspension control module has two 16-pin connectors. Disconnect air suspension control module 16-pin connector C296. Connector C296 has blank terminal No. 13. Inspect air suspension control module connector C296 for loose, damaged or corroded terminals. Repair as necessary. If connector is okay, go to next step.
- Measure resistance of Light Blue/White wire between air suspension control module connector C296 terminal No. 29 and Data Link Connector (DLC) terminal No. 7. See Figure and Fig 1 . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Light Blue/White wire between air suspension control module and DLC.
- Connect air suspension control module connector C296. Perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM. If air suspension control module responds to NGS tester, system is functioning properly. If air suspension control module does not respond to NGS tester, replace air suspension control module. See appropriate ELECTRONIC article in SUSPENSION.
