Inspection Procedure 2: Defective power supply system of the ignition switch

.

TECHNICAL DESCRIPTION (COMMENT)

When the power supply system of ignition switch has
a problem, none of the equipment and system con-
nected to the ignition switch works even if the ignition
switch is operated.

.

TROUBLESHOOTING HINTS

• The ignition switch may be defective

• The fuse No.14 may be defective

• The ETACS-ECU may be defective

• The wiring harness or connectors may have

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

DIAGNOSIS

Required Special Tools:

• MB992006: Extra fine probe

• MB991223: Harness set

STEP 1. Check ignition switch connector C-210 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ignition switch connector C-210 in good condition?

YES : Go to Step 2.
NO : Repair the defective connector.

STEP 2. Check the battery power supply circuit to the
ignition switch. Measure the voltage at ignition switch
connector C-210.
(1) Disconnect the connector, and measure at the wiring

harness side.

(2) Measure the voltage between terminal 1 and ground.

• The voltage should measure approximately 12 volts

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 6.
NO : Go to Step 3.

STEP 3. Check the fuse No.14.
Q: Is the check result normal?

YES : Go to Step 4.
NO : Replace the fuse No.14. (Check that there is not a

short to ground in the circuit of lower reaches before
replacing. If there are any problems, replace the fuse
after the circuit of lower reaches is repaired.)

STEP 4. Check ETACS-ECU connector C-317 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-317 in good condition?

YES : Go to Step 5.
NO : Repair the damaged parts.

STEP 5. Check the Wiring harness between ignition switch
connector C-210 (terminal No.1) and ETACS-ECU
connector C-317 (terminal No.3).

• Check the battery power supply line for open circuit.

Q: Is the check result normal?

YES : Go to Step 7.
NO : Repair the wiring harness.

STEP 6. Check the ignition switch.
Remove the ignition switch. Then check continuity between the
switch terminal.

Q: Is the ignition switch in good condition?

YES : Go to Step 7.
NO : Replace the ignition switch.

STEP 7. Retest the system.
Q: When the ignition switch is operated, do the equipment

and system work normally?
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.00-15

).

NO : Replace the ETACS-ECU.

ON-VEHICLE SERVICE

CHECK OF IGNITION KEY REMINDER WARNING
FUNCTION (STEERING LOCK REMINDER TONE
ALARM BY KOS)

M1541200700148

1. Close the driver's door, unlock the steering lock, and turn

the key (for the vehicle with KOS, the emergency key is
inversely inserted into the keyless operation key) to the
LOCK (OFF) position (the key is being inserted). <Vehicles
with WCM and vehicles with KOS (When using the emer-
gency key)>

2. Release the steering wheel lock with the driver's door

closed, and turn the IG knob to the position other than the
LOCK (OFF) position. <Vehicles with KOS (When not using
the emergency key)>

3. Change the driver's door state from closed to open.
4. Check that the tone alarm sounds normally.
5. If a malfunction is found, carry out the troubleshooting

(Refer to

P.54A-69

).

REMOVAL AND INSTALLATION

M1541200300560

CAUTION

Before removing the steering wheel assembly, refer to GROUP 52B

− Service Precautions

P.52B-25

and Air Bag Module and Clock Spring

P.52B-439

<Vehicles with WCM>.

CAUTION

After the installation, perform a calibration for the ASC-ECU to learn the steering wheel sensor neutral
point (Refer to GROUP 35C, On-vehicle Service

− Steering Wheel Sensor Calibration

P.35C-283

).

<Vehicles with WCM and ASC>

Pre-removal Operation
• Steering wheel straight-ahead position check. <Vehicles

with WCM>

• Removal of steering wheel assembly (Refer to GROUP

37

− Steering Wheel

P.37-31

). <Vehicles with WCM>

Post-installation Operation
• Installation of steering wheel assembly (Refer to GROUP

37

− Steering Wheel

P.37-31

). <Vehicles with WCM>

• Steering wheel straight-ahead position check. <Vehicles

with WCM>
