SYMPTOM PROCEDURES

Inspection Procedure A-1: Power supply circuit system abnormality of electric tailgate control unit.

CAUTION

Before replacing the ECU, ensure that the input 
and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM

If the electric tailgate control unit functions do not 
work at all, the electric tailgate control unit power 
supply system, earth system, or electric tailgate con-
trol unit may have a problem.

PROBABLE CAUSES

• Damaged wiring harness and connectors

• Malfunction of the electric tailgate control unit

DIAGNOSIS PROCEDURE

STEP 1. Resistance measurement at electric 
tailgate control unit connector.
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Measure the resistance between electric tailgate 

control unit connecter and body earth.

OK: Continuity exists (2 

Ω or less)

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Go to Step 2.

STEP 2. Check of open circuit in GND1 line 
between electric tailgate control unit connector 
and body earth.

Q: Is the check result normal?

YES : 

Intermittent malfunction (Refer to GROUP 

00 

− How to Use 

Troubleshooting/Inspection Service Points - 
How to Cope with Intermittent Malfunction .)

NO : 

Repair the connector(s) or wiring harness.

STEP 3. Voltage measurement at electric tailgate 
control unit connector (BAT2 and IG12 terminal).
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Measure the voltage between electric tailgate 

control unit connecter (BAT2 terminal) and body 
earth.

OK: System voltage

(3) Measure the voltage between electric tailgate 

control unit connecter (IG12 terminal) and body 
earth.

OK: System voltage (when ignition switch 
is ON)

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Go to Step 4.

STEP 4. Check of open circuit in BAT2 and IG12 
line between electric tailgate control unit 
connector and fusible link and OSS-ECU (IG1). 

Q: Is the check result normal?

YES : 

Intermittent malfunction (Refer to GROUP 

00 

− How to Use 

Troubleshooting/Inspection Service Points - 
How to Cope with Intermittent Malfunction .)

NO : 

Repair the connector(s) or wiring harness.

STEP 5. Voltage measurement at electric tailgate 
control unit connector (BAT1 terminal). 
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Measure the voltage between electric tailgate 

control unit connecter (BAT1 terminal) and body 
earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Go to Step 6.

STEP 6. Check of open circuit in BAT1 line 
between electric tailgate control unit connector 
and fusible link.

Q: Is the check result normal?

YES : 

Intermittent malfunction (Refer to GROUP 

00 

− How to Use 

Troubleshooting/Inspection Service Points - 
How to Cope with Intermittent Malfunction .)

NO : 

Repair the connector(s) or wiring harness.

STEP 7. System retest
Check that the electric tailgate control unit function 
works normally.

Q: Is the check result normal?

ETACS-ECU and the electric tailgate control unit, the 
ETACS-ECU itself or the electric tailgate control unit 
itself may be defective.

PROBABLE CAUSES

• Malfunction of ETACS-ECU

• Damaged electric tailgate control unit

• Damaged wiring harness and connectors

DIAGNOSIS PROCEDURE

STEP 1. Keyless entry system operation check.
Check that the door lock/unlock is performed when 
the keyless operation key is operated.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to GROUP 42B 

− Trouble Symptom 

Chart .

STEP 2. M.U.T.-III CAN bus diagnostics
Use M.U.T.-III to diagnose the CAN bus lines.

Q: Is the CAN bus normal?

YES : 

Go to Step 3.

NO : 

Repair the CAN bus line. (Refer to GROUP 
54C 

− CAN Bus Line Trouble Symptom 

Chart .)

STEP 3. M.U.T.-III diagnosis code
Check that ETACS-ECU sets a diagnosis code.

Q: Is the diagnosis code set?

YES : 

 Refer to GROUP 54A 

− Diagnosis Code 

Chart .

NO : 

Go to Step 4.

STEP 4. M.U.T.-III diagnosis code

electric tailgate control unit.

Q: Is the diagnosis code set?

YES : 

Refer to diagnosis code chart 

P.42A-77

.

NO : 

Go to Step 5.

STEP 5. M.U.T.-III data list
Check the signals related to the electric tailgate oper-
ation.
