TROUBLESHOOTING HINTS

DIAGNOSTIC PROCEDURE

Required Special Tools:

STEP 1. Check liftgate lock release handle connector F-09 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Is liftgate lock release handle connector F-09 in good condition?

YES : Go to Step 2.

NO : Repair or replace the damaged component(s). Refer to GROUP 00E, Harness Connector Inspection. Repair the liftgate lock release handle. If the liftgate lock release handle operates normally, a correct signal is sent from the liftgate lock release handle.

STEP 2. Check the liftgate lock release handle.

Remove the liftgate lock release handle. Refer to GROUP 42A, Liftgate Handle and Latch. Then check continuity between the switch terminals.

Q: Is the liftgate lock release handle in good condition?

YES : Go to Step 3.

NO : Repair the liftgate lock release handle. If the liftgate lock release handle operates normally, a correct signal is sent from the liftgate lock release handle.

STEP 3. Check the ground circuit to the liftgate lock release handle. Measure the resistance at liftgate lock release handle connector F-09.

Mitsubishi Outlander. Body

  1. Disconnect liftgate lock release handle connector F-09 and measure the resistance on the wiring harness side of the connector.
  2. Measure the resistance value between terminal 2 and ground.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 5.

NO : Go to Step 4.

STEP 4. Check the wiring harness between liftgate lock release handle connector F-09 (terminal 2) and ground.

Q: Is the wiring harness between liftgate lock release handle connector F-09 (terminal 2) and ground in good condition?

YES : No action is necessary and testing is complete.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector.

Repair the wiring harness as necessary. If the liftgate lock release handle operates normally, a correct signal is sent from the liftgate lock release handle.

STEP 5. Check ETACS-ECU connector C-313 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Is ETACS-ECU connector C-313 in good condition?

YES : Go to Step 6.

NO : Repair or replace the damaged component(s). Refer to GROUP 00E, Harness Connector Inspection. If the liftgate lock release handle operates normally, a correct signal is sent from the liftgate lock release handle.

STEP 6. Check the wiring harness between liftgate lock release handle connector F-09 (terminal 1) and ETACS-ECU connector C-313 (terminal 14).

NOTE: Also check intermediate connector D-12 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If intermediate connector D-12 is damaged, repair or replace the damaged component(s) as described in GROUP 00E, Harness Connector Inspection.

Q: Is the wiring harness between liftgate lock release handle connector F-09 (terminal 1) and ETACS-ECU connector C-313 (terminal 14) in good condition?

YES : Go to Step 7.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector.

Repair the wiring harness as necessary. If the liftgate lock release handle operates normally, a correct signal is sent from the liftgate lock release handle.

STEP 7. Using scan tool MB991958, check data list.

Check the signals related to the liftgate lock release handle operation.

CAUTION To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958.

Mitsubishi Outlander. Body

  1. Connect scan tool MB991958. Refer to GROUP 42B, "How to connect scan tool (M.U.T.-III)".
  2. Turn the ignition switch to the "ON" position.
  3. Check the data list of the ETACS.

Mitsubishi Outlander. Body

  1. Turn the ignition switch to the "LOCK" (OFF) position.

    OK: Normal condition is displayed.

Q: Is the check result normal?

YES : No action is necessary and testing is complete.

NO : Replace the ETACS-ECU. If the liftgate lock release handle operates normally, a correct signal is sent from the liftgate lock release handle.
