Battery Sensor Inspection
- Ignition "OFF"
- Connect VMI to KDS/GDS and set up an oscilloscope as follow (2-channel);
Channel A (+): Pin No. 2 (LIN Signal) terminal of Battery Sensor
Channel A (-): Ground
- Ignition "ON"
Specification : Refer to Figure below
- 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 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]
- Perform "PCM Neutral mode" procedure with KDS/GDS. (Refer to "IMMOBILIZER ")
- After finishing "ECM/PCM Neutral mode", perform "Key teaching" procedure with KDS/GDS. (Refer to "IMMOBILIZER ")
[In the case of installing new ECM/PCM]
Perform "Key teaching" procedure with KDS/GDS. (Refer to "IMMOBILIZER ")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/PCM Neutral mode" procedure with KDS/GDS. (Refer to "SMART KEY ")
- 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 Battery Sensor and then go to "Verification of Vehicle Repair " procedure.
