Testing Precautions
NOTE:
Air suspension diagnostics require using Rotunda STAR tester (007-00004), SUPER STAR II tester (004-00041) or equivalent. SUPER STAR tester (007-00019) cannot be used.
- Compressor relay, compressor vent solenoid and all air spring solenoids have internal diodes for noise suppression. DO NOT switch battery and ground feeds when testing components.
- When charging the battery, the ignition switch MUST be in the off position if air suspension switch in trunk is on. See Fig 1. If ignition switch is ON, air compressor relay or motor may be damaged.
