4.

Monitor "Battery Voltage" and "Battery Voltage(AMS)" parameter in "Current Data" with GDS.

5.

Test Condition : Ignition "ON" or Engine "ON"

Specification : Refer to Figure below

Fig.1) Battery voltage (AMS) and battery voltage (ECU) current data under engine idle.

6.

Is measured value within specification?

▶ Carefully re-do this troubleshooting guide steps.

▶ If the diagnostics have been performed correctly with no failure found, replace the ECM/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 Neutral mode" procedure with GDS. (Refer to "Immobilizer" in BE group)

2) After finishing "ECM Neutral mode", perform "Key teaching" procedure with GDS. (Refer to "Immobilizer" in BE group)

[In the case of installing new ECM/PCM]

Perform "Key teaching" procedure with GDS. (Refer to "Immobilizer" in BE group)

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. (Refer to "Smart key" in BE group)

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.

▶ Carefully re-do this troubleshooting guide steps.

▶ If problem still occurs, replace Battery Sensor and then go to "Verification of Vehicle Repair" procedure.
