G256924t6: CHECK THE ASU POWER SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal. 2. Remove fuse 52 of the rear power distribution box. 3. Measure the resistance between CR88, pin 01 (NW) and the output terminal of fuse 52.
^ 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
RECHECK the voltage to the ASU. If the voltage is high, check the charging system, Charging System - VIN Range: G00442->G45703
