STEP 2. Using scan tool MB991958, check data list.
Use the ETACS-ECU service data to check the signal related to
the operation of luggage compartment light.
• Open the trunk lid.
Q: Does scan tool MB991958 display the item "Trunk/gate
trunk ajar switch" as normal condition?
YES : (Normal condition is displayed.) Go to Step 3.
NO : (Normal condition is not displayed.) Troubleshoot the
ETACS-ECU. Refer to ETACS, Diagnosis, Input
signal chart
.
STEP 3. Check luggage compartment light connector F-01
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is luggage compartment light connector F-01 in good
condition?
YES : Go to Step 4.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
STEP 4. Luggage compartment light bulb check
Check that the luggage compartment light bulb is normal.
Q: Is luggage compartment light bulb normal?
YES : Go to Step 5.
NO : Replace the luggage compartment light bulb.
STEP 5. Check ETACS-ECU connector C-311 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connectors C-311 in good condition?
YES : Go to Step 6.

STEP 6. Check the wiring harness between luggage
compartment light connector F-01 (terminal 1, 2) and
ETACS-ECU connector C-311 (terminal 17, 3).
NOTE: Also check intermediate connector D-17 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector D-17 is damaged, repair or
replace the connector as described in GROUP 00E, Harness
Connector Inspection
.
Q: Is wiring harness between luggage compartment light
connector F-01 (terminal 1, 2) and ETACS-ECU
connector C-311 (terminal 17, 3) in good condition?
YES : Go to Step 7.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary.
STEP 7. Retest the system
Check that the luggage compartment light illuminates and
extinguishes normally.
Q: Do the trunk room work 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
NO : Replace the ETACS-ECU.
Inspection Procedure 4: 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
• Trunk lid latch switch
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.
