Component Inspection

■ Accelerator Position Sensor Inspection 

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

   Channel A (+): Pin No. 6 (APS1 Signal) terminal of Acceleration Pedal Position Sensor.

   Channel A (-): Ground

   Channel B (+): Pin No. 4 (APS2 Signal) terminal of Acceleration Pedal Position Sensor.

   Channel B (-): Ground

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

   Specification:  Refer to Figure below

5. Is 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 ECM 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 Neutral mode" procedure with GDS.
     2. After finishing "ECM Neutral mode", perform "Key teaching" procedure with GDS.

     
     [In the case of installing new ECM/PCM]
     Perform "Key teaching" procedure with GDS.
     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 GDS.
     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.
