Keyless Access System Touch Sensor Circuit Troubleshooting

1.

Keyless access system check:

Keyless access system check

?1.	Select KEYLESS ACCESS CONTROL UNIT from the ONE-PUSH START system select menu with the HDS, and enter HISTORY DATA.

?2.

Select HISTORY CLEAR, and back to TEST MODE menu:

NOTE: When the freeze data is cleared, the information indicates "NOT CONFIRMED".

	DRIVER DOOR UNLOCK SWITCH
	DRIVER DOOR LOCK SWITCH
	FRONT PASSENGER DOOR UNLOCK SWITCH
	FRONT PASSENGER DOOR LOCK SWITCH

?3.	Turn the vehicle to the OFF (LOCK) mode.

?4.	Get out of the vehicle with the keyless remote, and touch the each door outer handle touch sensors.

?5.	Select KEYLESS ACCESS CONTROL UNIT from the ONE-PUSH START system select menu with the HDS, and enter HISTORY DATA.

?6.

Recheck HISTORY DATA.

	DRIVER DOOR UNLOCK SWITCH
	DRIVER DOOR LOCK SWITCH
	FRONT PASSENGER DOOR UNLOCK SWITCH
	FRONT PASSENGER DOOR LOCK SWITCH

Is all the information OK?


	YES

Intermittent failure, the system is OK at this time.?


	NO

Go to step 2.

2.

Open wire check (GND line):

Open wire check (GND line)

?1.

Disconnect the following connectors.

Each door outer handle 8P connectors

?2.

Check for continuity between test points 1 and 2 individually.

Driver's door

Test condition	Vehicle OFF (LOCK) mode Driver's door outer handle 8P connector: disconnected
Test point 1	Driver's door outer handle 8P connector (female terminals) No. 8:
Test point 2	Body ground

Front passenger's door

Test condition	Vehicle OFF (LOCK) mode Front passenger's door outer handle 8P connector: disconnected
Test point 1	Front passenger's door outer handle 8P connector (female terminals) No. 8:
Test point 2	Body ground

Is there continuity?


	YES

The GND wires are OK. Go to step 3.


	NO

Repair an open or high resistance in the ground wire or poor ground (G401, G402).?

3.

Determine possible failure area (TS lines, DL lines, VOUT lines):

Determine possible failure area (TS lines, DL lines, VOUT lines)

?1.

Measure the voltage between test points 1 and 2 individually.

Driver's door

Test condition	Vehicle OFF (LOCK) mode Driver's door outer handle 8P connector: disconnected
Test point 1	Driver's door outer handle 8P connector (female terminals) No. 4:
Test point 2	Body ground

Front passenger's door

Test condition	Vehicle OFF (LOCK) mode Front passenger's door outer handle 8P connector: disconnected
Test point 1	Front passenger's door outer handle 8P connector (female terminals) No. 4:
Test point 2	Body ground

Is there battery voltage?


	YES

Go to step 4.


	NO

Go to step 7.

4.

Open wire check (TS lines, DL lines):

Open wire check (TS lines, DL lines)

?1.

Disconnect the following connector.

Body control module connector G (32P)

?2.

Check for continuity between test points 1 and 2 individually.

Driver's door

Test condition	Vehicle OFF (LOCK) mode Driver's door outer handle 8P connector: disconnected
Test point 1	Driver's door outer handle 8P connector (female terminals) No. 3:
Test point 2	Body control module connector G (32P) No. 22

Test point 1	Driver's door outer handle 8P connector (female terminals) No. 7:
Test point 2	Body control module connector G (32P) No. 19

Front passenger's door

Test condition	Vehicle OFF (LOCK) mode Front passenger's door outer handle 8P connector: disconnected
Test point 1	Front passenger's door outer handle 8P connector (female terminals) No. 3:
Test point 2	Body control module connector G (32P) No. 25

Test point 1	Front passenger's door outer handle 8P connector (female terminals) No. 7:
Test point 2	Body control module connector G (32P) No. 1

Is there continuity?


	YES

The TS and DL wires are not open. Go to step 5.


	NO

Repair an open or high resistance in the wire.?

5.

Shorted wire check (TS lines, DL lines):

Shorted wire check (TS lines, DL lines)

?1.

Check for continuity between test points 1 and 2 individually.

Test condition	Vehicle OFF (LOCK) mode Each door outer handle 8P connectors: disconnected Body control module connector G (32P): disconnected
Test point 1	Body control module connector G (32P) No. 22
Test point 2	Body ground

Test point 1	Body control module connector G (32P) No. 19
Test point 2	Body ground

Test point 1	Body control module connector G (32P) No. 25
Test point 2	Body ground

Test point 1	Body control module connector G (32P) No. 1
Test point 2	Body ground

Is there continuity?


	YES

Repair a short to ground in the wire.?


	NO

The TS and DL wires are OK. Go to step 6.

6.

Door outer handle touch sensor check (substitution):

Door outer handle touch sensor check (substitution)

?1.	Substitute a known-good door outer handle touch sensors, and recheck.

Is the system OK?


	YES

Faulty the original door outer handle touch sensor; replace the door outer handle.?


	NO

Replace the body control module.?

7.

Open wire check (VOUT lines):

Open wire check (VOUT lines)

?1.

Measure the voltage between test points 1 and 2 individually.

Test condition	Vehicle OFF (LOCK) mode Each door outer handle 8P connectors: disconnected
Test point 1	Body control module connector G (32P) No. 31
Test point 2	Body ground

Test point 1	Body control module connector G (32P) No. 30
