TROUBLE JUDGMENT

If the foot light does not illuminate normally, the
power supply circuit(s), ground circuit, or under cover
rear may have a problem.

.

TROUBLESHOOTING HINTS

• Malfunction of under cover rear

• Damaged harness wires and connectors

DIAGNOSIS

STEP 1. Check electric foot light connector D-102 (RH),
D-120 (LH) for loose, corroded or damaged terminals, or
terminals pushed back in the connector.
Q: Is the check result normal?

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

STEP 2. Measure the voltage at foot light connector D-102
(RH), D-120 (LH).
(1) Disconnect the connector, and measure at the wiring

harness side.

(2) Measure the voltage between the D-102 (RH), D-120 (LH)

electric folding second seat connector (terminal No. 1) and
the ground.

The voltage should measure approximately 12
volts (battery positive voltage).

Q: Does the voltage measure battery voltage?

YES : Go to Step 4.
NO : Go to Step 3.

STEP 3. Check the wiring harness between foot light
connector D-102 (RH), D-120 (LH) (terminal No. 1) and the
fusible link (34).
Check the power supply line for open or short circuit.
NOTE: Before the wiring harness check, check the relay box
connector C-308, and the intermediate connector C-35, C-32
and then repair them if necessary.
Q: Is wiring harness between foot light connector D-102

(RH), D-120 (LH) (terminal No. 1) and the fusible link (34)
in good condition?
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 : Repair the wiring harness.

STEP 4. Measure the resistance at foot light connector
D-102 (RH), D-120 (LH).
(1) Disconnect the connector, and measure at the wiring

harness side.

(2) Measure the resistance between the resistance at foot light

connector D-102 (RH), D-120 (LH) (terminal No. 5) and
ground.

The measured value should be continuity exists (2
Ω or less).

Q: Does the measured resistance value correspond with

this range?
YES : Go to Step 6.
NO : Go to Step 5.

STEP 5. Check the wiring harness between foot light
connector D-102 (RH), D-120 (LH) (terminal No. 5) and
ground.
Check the ground line for open circuit.
Q: Is wiring harness between foot light connector D-102

(RH), D-120 (LH) (terminal No. 5) and ground in good
condition?
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 : Repair the wiring harness.

STEP 6. Retest the system.
Check that the foot light illuminates normally.
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.00-15

).

NO : Replace the under cover rear.

Inspection Procedure 5: The interior light auto-cut function does not operate correctly.

.

TECHNICAL DESCRIPTION (COMMENT)

The ETACS-ECU operates the interior light auto-cut
function in accordance with the input signals below.

• Ignition switch (ACC)

• Ignition switch (IG1)

• Door switches

If this function does not work normally, these input
signal circuit(s) or the ETACS-ECU may have a prob-
lem. Also, "Interior light auto cut timer" may be set to
"0min" through customization.

.

TROUBLESHOOTING HINTS

• Malfunction of door switch

• Malfunction of the dome light

• Malfunction of the ETACS-ECU

• The wiring harness or connectors may have

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

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A (Vehicles with

CAN communication system)

STEP 1. Using scan tool MB991958, Check the
configuration function.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect

scan tool (M.U.T.-III)

P.54A-280

."

(2) Turn the ignition switch to the "ON" position.
(3) Use the ETACS-ECU customize function to check to see

which of the followings other than "0min" the "Interior light
auto cut timer" is set.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the check result normal?

YES : Go to Step 2.
NO : Use the ETACS-ECU configuration function to set the

"Interior light auto cut timer" to other than "0min"
(Refer to

P.54A-820

).

STEP 2. Using scan tool MB991958, read the ETACS-ECU
diagnostic trouble code.
Check if DTC is set to the ETACS-ECU.
(1) Turn the ignition switch to the "ON" position.
(2) Check whether the ETACS-ECU DTC is set.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES : Diagnose the ETACS-ECU. Refer to ETACS,
