- Disconnect the battery negative terminal.
- Disconnect the ASU electrical connector, CR91.
- Measure the resistance between CR91, pin 12 (NR).
- Is the resistance greater than 5 ohms?
- -> Yes: REPAIR the high resistance circuit. For additional information, refer to the appropriate SYSTEM WIRING DIAGRAMS article. CLEAR the DTC. TEST the system for normal operation.
- -> No: INSTALL a new air suspension relay. CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, contact dealer technical support for confirmation of possible module failure, and/or raise an EPQR.
