G239843t79 : CHECK THE MOTOR GROUNDS TO THE RMM
1. Reconnect the RMM electrical connector, CR37.
2. Disconnect the RMM electrical connector, CR59.
3. Disconnect the RMM electrical connector, CR41.
4. Measure the resistance between CR59, pin 01 (B) and GROUND.
5. Measure the resistance between CR41, pin 05 (B) and GROUND.
-
Is either resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. TEST the system for normal operation.
-> No
CHECK for DTCs indicating a network or module fault. REFER to the DTC index.
Check the Supplies and Grounds to the Restraints Module (RCM)
: CHECK THE SUPPLIES AND GROUNDS TO THE RESTRAINTS CONTROL MODULE (RCM)
G239843t94 : CHECK THE PERMANENT SUPPLY TO THE RCM
1. Disconnect the RCM electrical connector, CR86.
2. Measure the voltage between CR86, pin 12, (WU) and GROUND.
-
Is the voltage less than 10 volts?
-> Yes
REPAIR the circuit between the RCM and battery. This circuit includes the primary junction box (fuse 29). TEST the system for normal operation.
-> No
G239843t95 : CHECK THE GROUND TO THE RCM
1. Measure the resistance between CR86, pin 16 (B) and GROUND.
-
Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. TEST the system for normal operation.
-> No
CHECK for DTCs indicating a network or module fault. REFER to the DTC index.
Check the Supplies and Grounds to the Transmission Module (TCM)
: CHECK THE SUPPLIES AND GROUNDS TO THE TRANSMISSION CONTROL MODULE (TCM)
G239843t108 : CHECK THE PERMANENT SUPPLY TO THE TCM
1. Disconnect the TCM electrical connector, GB02.
2. Measure the voltage between GB02, pin 14 (NR) and GROUND.
-
Is the voltage less than 10 volts?
-> Yes
REPAIR the circuit between the TCM and battery. This circuit includes the front power distribution box (fuse 17). TEST the system for normal
operation.
-> No
G239843t109 : CHECK THE IGNITION SUPPLY TO THE TCM
1. Turn the ignition switch to the ON position.
