STEP 3. Measure at the lower metal part of the liftgate
switch in order to check the ground circuit to the liftgate
switch.
NOTE: Check that the liftgate switch is grounded to the vehicle
body by means of its mounting screw.
Remove the cap, and measure the resistance value between
the lower metal part and ground.
• The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 4.
NO : Check the fit of the switch, and repair if necessary.
Check that the input signal of liftgate switch is normal.
STEP 4. Check ETACS-ECU connector C-313 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-313 in good condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. Check that the input signal of liftgate switch
is normal.
STEP 5. Check the wiring harness between liftgate switch
connector F-12 (terminal 1) and ETACS-ECU connector
C-313 (terminal 5).
Check the input lines for open circuit and short circuit.
NOTE: Also check intermediate connector D-12 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector D-12 is damaged, repair or
replace the connector as described in GROUP 00E, Harness
Connector Inspection
.
Q: Is the wiring harness between liftgate switch connector
F-12 (terminal 1) and ETACS-ECU connector C-313
(terminal 5) in good condition?
YES : Replace the ETACS-ECU. Check that the input signal
of liftgate switch is normal.
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. Check that
the input signal of liftgate switch is normal.

Inspection Procedure 10: ETACS-ECU does not receive any signal from the hood switch.
.
TECHNICAL DESCRIPTION (COMMENT)
If there is an error to the hood switch input signal, the
hood switch signal is no longer output to the commu-
nication line.
.
TROUBLESHOOTING HINTS
• The hood switch 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:
• MB991223: Harness Set
• MB992006: Extra Fine Probe

STEP 1. Check hood switch connector A-06 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is hood switch connector A-06 in good condition?
YES : Go to Step 2.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. Check that the input signal of hood switch is
normal.
STEP 2. Check the hood switch.
Remove the hood switch. Then check continuity between the
switch terminals.
Q: Is the hood switch in good condition?
YES : Go to Step 3.
NO : Replace the hood switch. Check that the input signal
of hood switch is normal.
STEP 3. Check the ground circuit to the hood switch. Test
at hood switch connector A-06.
(1) Disconnect hood switch connector A-06 and measure the
resistance available at the wiring harness side of the
connector.
(2) Measure the resistance value between terminal 2 and
ground.
• The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 5.
NO : Go to Step 4.

STEP 4. Check the wiring harness between hood switch
connector A-06 (terminal 1) and ground.
Check the ground wires for open circuit.
Q: Is the wiring harness between hood switch connector
A-06 (terminal 1) and the ground in good condition?
YES : No action is necessary and testing is complete.
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. Check that
the input signal of hood switch is normal.
STEP 5. Check ETACS-ECU connector C-312 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-312 in good condition?
YES : Go to Step 6.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. Check that the input signal of hood switch is
normal.
STEP 6. Check the wiring harness between driver's door
switch connector A-06 (terminal 2) and ETACS-ECU
connector C-312 (terminal 12).
Check the input lines for open circuit and short circuit.
Q: Is the wiring harness between driver's door switch
connector A-06 (terminal 2) and ETACS-ECU connector
C-312 (terminal 12) in good condition?
YES : Replace the ETACS-ECU. Check that the input signal
of hood switch is normal.
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. Check that
the input signal of hood switch is normal.
