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 Fig 1 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 ECM/PCM, the vehicle equipped with the immobilizer must be performed procedure as below.
     [In the case of installing used ECM/PCM]
     

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

     
     [In the case of installing new ECM/PCM]
     Perform "Key teaching" procedure with KDS/GDS. (Refer to IMMOBILIZER SYSTEM )
     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/PCM Neutral mode" procedure with KDS/GDS. (Refer to "SMART KEY ")
     2. After finishing "ECM/PCM Neutral mode", insert the key (or press the start button) and turn it to the IGN ON and OFF position. Then the 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.
