Component Inspection
- Ignition "OFF"
- Connect VMI to GDS and set up an oscilloscope as follow (2-channel);
Channel A (+): Battery (+) terminal.
Channel A (-): Ground
Channel B (+): Battery (-) terminal.
Channel B(-): Ground
- Ignition "ON" & Engine "ON"
Specification: Approx. 14.5V
- Is the measured value within specification?
YES
- 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]- Perform "ECM Neutral mode" procedure with GDS.
- 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]- Perform "ECM Neutral mode" procedure with GDS.
- 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
- If voltage fluctuates, check circuit for loose, bent or corroded terminals, Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- If the diagnostics have been performed correctly with no failure found, replace the ECM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
