B1671

B1671; BATTERY VOLTAGE OUT OF RANGE

G256924t5: CHECK THE POWER SUPPLY TO THE ASU
1. Disconnect the ASU electrical connector, CR88.
2. Measure the voltage between CR88, pin 01 (NW) and GROUND.
^ Is the voltage approximately 10 volts?
-> Yes
RECHECK DTCs.
-> No

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 ohms?
-> Yes
REPAIR the high resistance circuit. 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,
