G552799t11 : CHECK THE GLOW PLUG OUTPUT CIRCUITS FOR HIGH 1. Measure the resistance between: EC74, harness side EC76, harness side Pin 01
Pin 01
Pin 02
Pin 02
Pin 03
Pin 03
EC74, harness side EC77, harness side Pin 04
Pin 01
Pin 05
Pin 02
Pin 06
Pin 03
Is the resistance less than 10 ohms? -> Yes If DTCs P0380 or P0382 are logged and the tests above have not identified a circuit fault, a control module may be at fault.
-> No REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. Clear the DTC, test the system for normal operation.
