Inspection Procedure N-6

INSPECTION PROCEDURE N-6: ETACS-ECU does not receive any signal from the liftgate lock release handle. [ECLIPSE]


















CIRCUIT OPERATION

The ETACS-ECU operates the liftgate according to signal from the liftgate lock release handle.

TECHNICAL DESCRIPTION (COMMENT)

If the signal is not normal, the liftgate do not work normally. If the signal is not normal, the liftgate lock release handle or the ETACS-ECU may be defective.

TROUBLESHOOTING HINTS

- The liftgate lock release handle may be defective
- The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector
- The ETACS-ECU may be defective

DIAGNOSIS

Required Special Tools:

- MB991223: Harness Set
- MB992006: Extra Fine Probe

STEP 1. Check liftgate lock release handle connector F-06 for loose, corroded or damaged terminals, or terminals pushed back in the connector.





Q. Is liftgate lock release handle connector F-06 in good condition?

YES Go to Step 2.

NO Repair or replace the damaged component(s). 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. Liftgate. 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-06.





(1)Disconnect liftgate lock release handle connector F-06 and measure the resistance available at the wiring harness side of the connector.





(2)Measure the resistance value between terminal 2 and ground.

- The resistance should be 2 ohms or less.

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-06 (terminal 2) and ground.

- Check the ground wire for open circuit.





Q. Is the wiring harness between liftgate lock release handle connector F-06 (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-219 for loose, corroded or damaged terminals, or terminals pushed back in the connector.





Q. Is ETACS-ECU connector C-219 in good condition?

YES Go to Step 6.

NO Repair or replace the damaged component(s). 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-06 (terminal 1) and ETACS-ECU connector C-219 (terminal 41).

- Check the communication lines for open circuit and short circuit.













NOTE:
Also check junction block connectors C-23 and F-02 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If junction block connector C-23 or F-02 is damaged, repair or replace the damaged component(s) as described in Harness Connector Inspection Harness Connector Inspection.

Q. Is the wiring harness between liftgate lock release handle connector F-06 (terminal 1) and ETACS-ECU connector C-219 (terminal 41) in good condition?

YES Replace the ETACS-ECU. When the ETACS-ECU is replaced, register the encrypted code. Immobilizer System. If the liftgate lock release handle operates normally, a correct signal is sent from the liftgate lock release handle.

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.
