DIAGNOSIS PROCEDURE


STEP 1. M.U.T.-III data list



  • Refer to Data List Reference Table .

  1. item 6: Clutch monitoring switch (upper)

Q. Is the check result normal?

Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Go to Step 2.

STEP 2. Check the installation state of the clutch monitoring switch and check the clutch pedal.



  • Check the installation state of the clutch monitoring switch.
  • Check whether the installation portion of the clutch monitoring switch of the clutch pedal is not damaged.

Q. Is the check result normal?

Go to Step 3.
Repair or replace.

STEP 3. Check the clutch monitoring switch itself.



  • Check the clutch monitoring switch itself (Refer to GROUP 21A - Clutch Pedal - Inspection ).

Q. Is the check result normal?

Go to Step 4.
Replace the clutch monitoring switch.

STEP 4. Perform voltage measurement at clutch monitoring switch connector.



  • Disconnect connector, and measure at harness side.
  • Ignition switch: ON
  • Voltage between terminal AS&G-ECU CLT1 line and earth.
OK: System voltage

Q. Is the check result normal?

Go to Step 7.
Go to Step 5.

STEP 5. Check of short to earth, and open circuit in CLT1 line between AS&G-ECU connector and clutch monitoring switch connector.


Q. Is the check result normal?

Go to Step 6.
Repair the connector(s) or wiring harness.

STEP 6. M.U.T.-III diagnosis code



  • Reconfirmation of the diagnosis code.

Q. Is the diagnosis code set?

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

STEP 7. Perform resistance measurement at clutch monitoring switch connector terminal.



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

Q. Is the check result normal?

Go to Step 8.

    Repair the connector(s), or check of open circuit, and harness damage in earthing line between clutch monitoring switch connector and body earth.

STEP 8. Check harness damage in CLT1 line between AS&G-ECU connector and clutch monitoring switch connector.


Q. Is the check result normal?

Go to Step 6.
Repair the connector(s) or wiring harness.
