Component Inspection

■ Accelerator Position Sensor Inspection 

1. Ignition "OFF".
2. Connect VMI to KDS/GDS and set up an oscilloscope as follow (2-channel);

   Channel A (+): Pin No. 3 (APS1 Signal) terminal of Accelerator Pedal Position Sensor.

   Channel A (-): Ground

   Channel B (+): Pin No. 6 (APS2 Signal) terminal of Accelerator Pedal Position Sensor.

   Channel B (-): Ground

3. Ignition "ON"
4. Testing Condition: Accelerator Pedal Operation.

   Specification:  Refer to below

5. Is the measured value within specification?

   YES 

   • Carefully re-do this troubleshooting guide steps.
   • If the diagnostics have been performed correctly with no failure found, replace the PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
     CAUTION: When replacing the PCM, the vehicle equipped with the immobilizer must be performed procedure as below.
     [In the case of installing used PCM]

     1. Perform "PCM Neutral mode" procedure with KDS/GDS. (Refer to "IMMOBILIZER REPAIR PROCEDURES ")
     2. After finishing "PCM Neutral mode", perform "Key teaching" procedure with KDS/GDS. (Refer to "IMMOBILIZER REPAIR PROCEDURES ")

     
     [In the case of installing new PCM]
     perform "Key teaching" procedure with KDS/GDS. (Refer to "IMMOBILIZER REPAIR PROCEDURES ")
     CAUTION: When replacing the ECM/PCM, the vehicle equipped with the smart key system (Button start) must be performed procedure as below.
     [In the case of installing used ECM/PCM]

     1. Perform "ECM Neutral mode" procedure with KDS/GDS. (Refer to "SMART KEY ")
     2. After finishing "ECM Neutral mode", insert the key (or press the start button) and turn it to the IGN ON and OFF position. Then the ECM/PCM learns the smart key information automatically.

     
     [In the case of installing new ECM/PCM]
     Insert the key (or press the start button) and turn it to the IGN ON and OFF position. Then the ECM/PCM learns the smart key information automatically.

   NO 

   • Carefully re-do this troubleshooting guide steps.
   • If no problems were found with the circuits or connectors, replace Acceleration Pedal Position Sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
