Step 3. Check the wiring harness between C-141
engine-A/T-ECU connector terminal No.79 and
C-219 ETACS-ECU connector terminal No.63.

NOTE:

Prior to the wiring harness inspection, check joint
connector C-02 <L.H. driver vehicles>, combination
meter connector C-04 <R.H. drive vehicles> and
intermediate connector C-105, and repair if
necessary.

•

Check the input line for open circuit.

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Repair the wiring harness.

Step 4. Check the speedometer.

Check that the speedometer works normally.

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Replace the engine-A/T-ECU.

Step 5. Retest the system.

Check that the vehicle speed signal is received
normally.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the ETACS-ECU.

INSPECTION PROCEDURE N-14: Each switch signal of the keyless entry transmitter is not received.

CAUTION

Whenever the ECU is replaced, ensure that the
input signal circuit is normal.

COMMENTS ON TROUBLE SYMPTOM
Input signal from the keyless entry transmitter is
used to operate the keyless entry system. If the
signal is abnormal, the keyless entry system will not
work normally.

POSSIBLE CAUSES

•

Malfunction of the keyless entry transmitter

•

Defective battery of the keyless entry transmitter

•

Malfunction of the ETACS-ECU

DIAGNOSTIC PROCEDURE

Step 1. Pulse check

Check whether the ETACS-ECU receives signal from
a transmitter or not. For this check, you should use
the 2-button-type transmitter (integrated with a key),
which cover screw is silver and has already been
registered.
NOTE: For how to register the keyless entry
transmitter encrypted code, refer to GROUP 42

−

On-vehicle Service

P.42-54

.

OK: The MUT-II/III sounds or the voltmeter
needle fluctuates.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Go to Step 4.

Step 2. Check the transmitter battery.

Refer to GROUP 42

.

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Replace the keyless entry transmitter
battery.

Step 3. Register the encrypted code, and then
retest the system.
(1) Register the keyless entry transmitter again.
(2) Check that each signal is received from the

keyless entry transmitter.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the keyless entry transmitter.

Step 4. Retest the system.

Check that each signal is received from the keyless
entry transmitter.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the ETACS-ECU.

INSPECTION PROCEDURE N-15: The front fog lamp switch signal is not received.

CAUTION

Whenever the ECU is replaced, ensure that the
input signal circuit is normal.

COMMENTS ON TROUBLE SYMPTOM
Input signal from the front fog lamp switch is used to
operate the front fog lamps. If the signal is abnormal,
the front fog lamps will not illuminate and extinguish
normally.

POSSIBLE CAUSES

•

Malfunction of the fog lamp switch

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Connector check: C-03 fog lamp switch
connector

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Repair the defective connector.

Step 2. Check the front fog lamp switch.

Refer to GROUP 54A

−

.

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Replace the fog lamp switch.

Step 3. Measure the resistance at the C-03 fog
lamp switch connector.

(1) Remove the fog lamp switch, and measure at the

wiring harness side.

(2) Resistance between C-03 fog lamp switch

connector terminal No.2 <L.H. drive vehicles> or
terminal No.6 <R.H. drive vehicles> and body
earth

OK: 2

Ω

or less

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Go to Step 4.
