G256924p17: C1830; Relay Drive Circuit Fault

PINPOINT TEST G256924p17: C1830; RELAY DRIVE CIRCUIT FAULT
G256924t5l: CHECK THE RELAY DRIVE CIRCUIT FOR SHORT TO B+
1. Remove the air suspension relay. 2. Measure the voltage between the relay base, pin 02, and GROUND.
^ Is the voltage greater than 3 volts?
^ Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
^ No
GO to Pinpoint Test G256924t48.

G256924t48: CHECK THE RELAY DRIVE CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between the relay base, pin 02, and GROUND.
^ Is the resistance less than 10,000 ohms?
^ Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
^ No
GO to Pinpoint Test G256924t52.

G256924t52: CHECK THE RELAY DRIVE CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal. 2. Disconnect the ASU electrical connector, CR91. 3. Measure the resistance between CR91, pin 12 (NR).
^ Is the resistance greater than 5,000 ohms?
^ Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. 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.
