Troubleshooting for CC1: Short circuit to +12 V
NOTE
Priorities when dealing with a number of faults:
If fault "DTC P0225: APP Sensor (Main) Circuit: For Diesel Engine Model" is present at the same time,
check that the sensor is connected correctly.
Check the connections of the accelerator pedal position (APP) sensor.
Check the ECM connections.
Repair if necessary.
Check the continuity and insulation in relation to +12 V of the following connections:
• Between "E68-6" wire of accelerator pedal position (APP) sensor connector and "E66-21" terminal of ECM
connector
• Between "E68-1" wire of accelerator pedal position (APP) sensor connector and "E66-15" terminal of ECM
connector
• Between "E68-5" wire of accelerator pedal position (APP) sensor connector and "E66-27" terminal of ECM
connector
Repair if necessary.
Measure the resistance on the accelerator pedal position (APP) sensor (sub) on accelerator pedal position
(APP) sensor assembly between "E68-1" and "E68-5" terminals.
Replace the accelerator pedal position (APP) sensor assembly if its resistance is not approximately: 0.8 – 4.9
kΩ.
Troubleshooting for D1: Inconsistency of signal
Check the fuel pressure sensor connectors.
Check the ECM connections.
Repair if necessary.
Check the following connections for continuity and make sure there is no interference resistance:
• Between "E68-6" wire of accelerator pedal position (APP) sensor connector and "E66-21" terminal of ECM
connector
• Between "E68-1" wire of accelerator pedal position (APP) sensor connector and "E66-15" terminal of ECM
connector
• Between "E68-5" wire of accelerator pedal position (APP) sensor connector and "E66-27" terminal of ECM
connector
• Between "E68-3" wire of accelerator pedal position (APP) sensor connector and "E66-3" terminal of ECM
connector
• Between "E68-2" wire of accelerator pedal position (APP) sensor connector and "E66-4" terminal of ECM
connector
• Between "E68-4" wire of accelerator pedal position (APP) sensor connector and "E66-5" terminal of ECM
connector
Repair if necessary.
If the fault is still present, replace the accelerator pedal position (APP) sensor assembly.
