Perform Fuel Pump Relay Actuation Test
- Connect KDS/GDS to Data Link Connector (DLC).
- Ignition "ON" & Engine "OFF"
- Perform "Fuel Pump Relay" in "Actuation Test " with KDS/GDS.
- Monitor "Fuel Pump ON" parameter in "Current Data
" with KDS/GDS.
Specification: Refer to Figure below (Also, operating sound (Motor sound) is heard)
- Is parameter displayed within specification?
YES
- 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]- Perform "ECM Neutral mode" procedure with KDS/GDS. (Refer to "IMMOBILIZER ")
- After finishing "ECM 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 Neutral mode" procedure with KDS/GDS. (Refer to "SMART KEY ")
- 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 Fuel pump control module and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.CAUTION:
- Install the component with the specified torques.
- Note that internal damage may occur when the component is dropped or mistreated.
