Step 16. Check the wiring harness from B-132
ETACS-ECU connector terminal Nos.22 and 23 to
E-05 tailgate lock actuator connector terminal
Nos. 2 and 1.

NOTE:

Prior to the wiring harness inspection, check interme-
diate connector C-12, and repair if necessary.

• Check the input and output lines for open circuit.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

− How to

use Troubleshooting/inspection Service
Points

− How to Cope with Intermittent

Malfunction

P.00-13

).

NO :

Repair the wiring harness.

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-61

INSPECTION PROCEDURE C-3: Selector "P" position-linked door unlock function does not operate.
<CVT>

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENT ON TROUBLE SYMPTOM

If the doors are not unlocked when the selector lever
is shifted to the P position, the shift position signal
input circuit(s) or the ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Checking central door unlocking
operation
Check that the central door locking system works
normally.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Refer to Inspection Procedure C-1 "Central
door locking system does not work

P.54B-52

."

Step 2. M.U.T.-III other system diagnosis code
Check whether the engine-CVT-ECU-related diagno-
sis code is set.

Q: Is the diagnosis code set?

YES :

Diagnose the CVT (Refer to GROUP 23A

−

Troubleshooting

P.23A-14

).

NO :

Go to Step 3.

Step 3. Retest the system.
Check that shifting the selector lever to the P position
unlocks the doors.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

− How to

use Troubleshooting/inspection Service
Points

− How to Cope with Intermittent

Malfunction

P.00-13

).

NO :

Replace the ETACS-ECU.

COMMENTS ON TROUBLE SYMPTOM

If the power windows do not work at all, the power
window relay, the power window main switch or the
ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the power window relay

• Malfunction of the power window main switch

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Pulse check
Check the input signal from the ignition switch.

OK: The M.U.T.-III sounds or the voltmeter
needle fluctuates.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Refer to Inspection Procedure A-2 "When
the ignition switch is at the LOCK (OFF)
position, the functions do not work normally.
Check the battery power supply circuit to
the ETACS-ECU

P.54B-43

."

Step 2. Connector check: D-03 power window
main switch connector

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Repair the defective connector.

Step 3. Check the power window main switch.
Refer to GROUP 42

− Door

P.42-42

.

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Replace the power window main switch.

Step 4. Voltage measurement at the D-03 power
window main switch connector.

(1) Disconnect the connector, and measure at the

wiring harness side.

(2) Ignition switch: ON

(3) Voltage between D-03 power window main switch

connector terminal No.10 and body earth.

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 13.

NO :

Go to Step 5.

Step 5. Connector check: B-126 power window
relay connector

Q: Is the check result normal?

YES :

Go to Step 6.
