FAIL-SAFE AND BACKUP FUNCTION




PROBABLE CAUSES




DIAGNOSIS PROCEDURE


STEP 1. Perform resistance measurement at electronic-controlled throttle valve connector.



  • Disconnect connector, and measure at harness side.
  • Resistance between terminal engine-ECU TPSE line and body earth.
OK: Continuity (2 Ω or less)

Q. Is the check result normal?

Go to Step 4.
Go to Step 2.

STEP 2. Check harness between electronic-controlled throttle valve connector terminal and engine-ECU connector terminal TPSE.



  • Check earthing line for damage.

Q. Is the check result normal?

Go to Step 3.
Repair or replace the connector, repair the damaged harness wire.

STEP 3. M.U.T.-III diagnosis code



  • Reconfirmation of diagnosis code.

Q. Is diagnosis code stored?

Replace the engine-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).

STEP 4. Check harness between electronic-controlled throttle valve connector terminal and engine-ECU connector terminal TPS5.



  • Check power supply line for damage.

Q. Is the check result normal?

Go to Step 5.
Repair or replace the connector repair the damaged harness wire.

STEP 5. Check harness between electronic-controlled throttle valve connector terminal and engine-ECU connector terminal TPSM.



  • Check output line for damage.

Q. Is the check result normal?

Go to Step 6.
Repair or replace the connector repair the damaged harness wire.

STEP 6. Check harness between electronic-controlled throttle valve connector terminal and engine-ECU connector terminal TPSS.



  • Check output line for damage.

Q. Is the check result normal?

Go to Step 7.
Repair or replace the connector repair the damaged harness wire.

STEP 7. Replace throttle body assembly.



  • After replacing the throttle body assembly, reconfirm whether the diagnosis code is stored.

Q. Is the diagnosis code stored?

Replace the engine-ECU.
Check end.
