Troubleshooting for CC1: Short circuit to +12 V
Check the connections of the accelerator pedal position (APP) sensor.
Check the ECM connections.
Repair if necessary.
Check for continuity and insulation from the +12 V feed on the following connections:
• 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.
Measure the resistance on the accelerator pedal position (APP) sensor (main) on accelerator pedal position
(APP) sensor assembly between "E68-4" and "E68-2".
Replace the accelerator pedal position (APP) sensor assembly if the resistance is not approximately 0.8 – 2.6
kΩ.
Troubleshooting for D1: Inconsistency of signal
Check the connections of the accelerator pedal position (APP) sensor.
Check the ECM connections.
Repair if necessary.
Check the following connections for continuity and make sure there is no interference resistance:
• 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
• 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
If the fault is still present, replace the accelerator pedal position (APP) sensor assembly.
Troubleshooting for D2: Accelerator pedal position (APP) sensor locked
Check the mechanical status of the accelerator pedal:
• Locked in full load position.
• Pedal blocked by an external component.
Repair if necessary.
Vary the position of the pedal and display the parameter "Pedal position" on Data List of SUZUKI scan tool.
If the values displayed are inconsistent, replace the accelerator pedal position (APP) sensor assembly.
