XJ (X308) V8-4.0L SC (2003)
: CHECK THE SUPPLIES AND GROUNDS TO THE REAR ENTERTAINMENT CONTROL PANEL
G239843t61 : CHECK THE PERMANENT SUPPLY TO THE REAR ENTERTAINMENT CONTROL PANEL
1. Disconnect the rear entertainment control panel electrical connector, TL20.
2. Measure the voltage between TL20, pin 08 (RW) and GROUND.
-
Is the voltage less than 10 volts?
-> Yes
REPAIR the circuit between the rear entertainment control panel and battery. This circuit includes the primary junction box (fuse 30). TEST the system
for normal operation.
-> No
G239843t62 : CHECK THE GROUND TO THE REAR ENTERTAINMENT CONTROL PANEL
1. Measure the resistance between TL20, pin 10 (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 wake-up circuit or optical ring fault. REFER to the DTC index.

G239843t72 : CHECK THE PERMANENT SUPPLY TO THE REM
1. Disconnect the REM electrical connector, CR04.
2. Measure the voltage between CR04, pin 03 (NW) and GROUND.
-
Is the voltage less than 10 volts?
-> Yes
REPAIR the circuit between the REM and battery. This circuit includes the primary junction box (fuse 42). TEST the system for normal operation.
-> No
G239843t73 : CHECK THE SWITCHED SYSTEM POWER (SSP) SUPPLY TO THE REM
1. Reconnect the REM electrical connector, CR04.
2. Disconnect the REM electrical connector, CR13.
3. Make sure the SSP relay is energized.
4. Measure the voltage between CR13, pin 06 (N) and GROUND.
-
Is the voltage less than 10 volts?
