XJ (X308) V8-4.0L SC (2003)
REPAIR the circuit between the A/CCM and battery. This circuit includes the primary junction box (fuse 01) and the ignition switch. TEST the system
for normal operation.
-> No
G239843t104 : CHECK THE SWITCHED SYSTEM POWER (SSP) SUPPLY TO THE A/CCM
1. Make sure the SSP relay is energized.
2. Measure the voltage between CR119, pin 02 (N) and GROUND.
-
Is the voltage less than 10 volts?
-> Yes
REPAIR the circuit between the A/CCM and battery. This circuit includes the primary junction box (fuse 28). TEST the system for normal operation.
-> No
G239843t105 : CHECK THE SYSTEM GROUND TO THE A/CCM
1. Measure the resistance between CR119, pin 22 (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 Air Suspension Module
: CHECK THE SUPPLIES AND GROUNDS TO THE AIR SUSPENSION CONTROL MODULE (ASU)
G239843t114 : CHECK THE PERMANENT SUPPLY TO THE ASU
1. Disconnect the ASU electrical connector, CR88.
2. Measure the voltage between CR88, pin 01 (NW) and GROUND.
