STEP 5. Check the wiring harness between driver's door 
switch connector F-14 (terminal 1) and ETACS-ECU 
connector D-222 (terminal 9).

NOTE: Also check intermediate connector D-125 and junction 
block connector D-217 for loose, corroded, or damaged termi-
nals, or terminals pushed back in the connector. If junction 
block connector D-217 or intermediate connector D-125 is 
damaged, Repair or replace the damaged component(s) as 
described in GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between driver's door switch 

connector F-14 and ETACS-ECU connector D-222 in 
good condition?
YES : Replace the ETACS-ECU. If the functions, which are 

described in "CIRCUIT OPERATION", work normally, 
the input signal from the driver's door switch should 
be 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. If the 
functions, which are described in "CIRCUIT 
OPERATION", work normally, the input signal from 
the driver's door switch should be normal.

STEP 6. Check the passenger's door switch.
Remove the passenger's door switch. Then check the continu-
ity between the switch terminals and the switch body.

Q: Is the passenger's door switch in good condition?

YES : Go to Step 7.
NO :  Replace the passenger's door switch. If the functions, 

which are described in "CIRCUIT OPERATION", work 
normally, the input signal from the passenger's door 
switch should be normal.

STEP 7. Measure at the lower metal part of the passenger's 
door switch in order to check the ground circuit to the 
passenger's door switch.
NOTE: Check that the passenger's door 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 the ground. 

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 8.
NO :  Check the fit of the switch, and repair if necessary. If 

the functions, which are described in "CIRCUIT 
OPERATION", work normally, the input signal from 
the passenger's door switch should be normal.

STEP 8. Check passenger's door switch connector F-22 
and ETACS-ECU connector D-224 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector. 
Q: Are passenger's door switch connector F-22 or ETACS-

ECU connector D-224 in good condition?
YES : Go to Step 9.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. If the functions, which are described in 

"CIRCUIT OPERATION", work normally, the input 
signal from the passenger's door switch should be 
normal.

STEP 9. Check the wiring harness between passenger's 
door switch connector F-22 (terminal 1) and ETACS-ECU 
connector D-224 (terminal 29).

NOTE: Also check joint connector D-01 and intermediate con-
nector D-111 for loose, corroded, or damaged terminals, or ter-
minals pushed back in the connector. If joint connector D-01 or 
intermediate connector D-111 is damaged, Repair or replace 
the damaged component(s) as described in GROUP 00E, Har-
ness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between passenger's door switch 

connector F-22 (terminal 1) and ETACS-ECU connector 
D-224 (terminal 2) in good condition?
YES : Replace the ETACS-ECU. If the functions, which are 

described in "CIRCUIT OPERATION", work normally, 
the input signal from the passenger's door switch 
should be 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. If the 
functions, which are described in "CIRCUIT 
OPERATION", work normally, the input signal from 
the passenger's door switch should be normal.
