Test N: The Air Suspension Indicator Is Never/Always On (If Equipped)

PINPOINT TEST N: THE AIR SUSPENSION INDICATOR IS NEVER/ALWAYS ON (IF EQUIPPED)

Normal Operation
The air suspension warning indicator flashes and then stays on with the ignition switch in the RUN position and the air suspension service switch turned off or when a system malfunction is detected. The instrument cluster (IC) receives the air suspension status message from the air suspension module over the high speed controller area network (HS-CAN). If a fault occurs in the air suspension system, a DTC is set and the air suspension module sends a CAN message to the instrument cluster (IC) to illuminate the air suspension indicator.

This pinpoint test is intended to diagnose the following:
- Air suspension system
- Air suspension module
- Instrument cluster (IC)
