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 

P.00E-2

. 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 

P.00E-2

.

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

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 

P.00E-2

. 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 

P.00E-2

. 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
