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.

ZC5015300000

Harness side: D-102, D-120

(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).

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.

ZC5015310006

Harness side: D-102, D-120

(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.

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.

M15410900128USA0000010000

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
problem. 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  terminals
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)

To prevent damage to scan tool MB991958, always turn the
ignition  switch  to  the  "LOCK"  (OFF)  position  before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958. Refer to "How to connect scan
tool (M.U.T.-III) P.54Ac-139."

(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.54Ac-190).

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 GROUP 54Ad -

Diagnosis P.54Ad-8).

NO:

 Go to Step 3.

STEP 3. Using scan tool MB991958, check data list.
Use the ETACS-ECU data list to check the signals related to the
interior light auto-cut function.

Turn the ignition switch to the "ACC" position.

Turn the ignition switch to the "LOCK" (OFF) position.
