Keyless Access System Touch Sensor Circuit Troubleshooting (2014 - 2015)

WARNING: This page is about a different variant/trim than selected.

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. Press the engine start/stop button to select the OFF mode.

- 4. Get out of the vehicle with the keyless remote, and touch the driver's or front passenger's door outer handle touch sensor and push the lock button.

- 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.

Open wire check (GND lines):

- 1. Disconnect the following connectors.

Each door outer handle 8P connector

- 2. Check for continuity between test points 1 and 2 individually.

Driver's door

Test condition	OFF mode Driver's door outer handle 8P connector: disconnected
Test circuit	GND
Test point 1	Driver's door outer handle 8P connector No. 8 (BLK)
Test point 2	Body ground

Front passenger's door

Test condition	OFF mode Front passenger's door outer handle 8P connector: disconnected
Test circuit	GND
Test point 1	Front passenger's door outer handle 8P connector No. 8 (BLK)
Test point 2	Body ground

Is there continuity?

YES

The GND wires are OK. Go to step 3.

Repair an open or high resistance in the ground wire or poor ground (G502, G504).

Determine possible failure area (TS_FR line, VOUT_FR lines):

- 1. Measure the voltage between test points 1 and 2 individually.

Is there battery voltage?

YES

Go to step4.

Go to step 7.

Open wire check (TS_FR_DR, TS_FR_AS lines):

- 1. Disconnect the following connector.

Keyless access control unit connector A (32P)

- 2. Connect terminals A and B with jumper wires.

Is there continuity?

YES

The TS_FR_DR and TS_FR_AS wires are not open. Go to step 5.

Repair an open or high resistance in the wire.

Shorted wire check (TS_FR_DR, TS_FR_AS lines):

- 1. Remove the jumper wire from the touch sensor.

- 2. Check for continuity between test points 1 and 2 individually.

Test condition	OFF mode Each door outer handle 8P connector: disconnected Keyless access control unit connector A (32P): disconnected

Is there continuity?

YES

Repair a short to ground in the wire.

The TS_FR_DR and TS_FR_AS wires are OK. Go to step 6.

Door outer handle check (substitution):
- 1. Substitute a known-good door outer handle touch sensor, and recheck.

Is the system OK?

YES

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

NO

Replace the keyless access control unit .

Open wire check (VOUT_FR_DR, VOUT_FR_AS lines):

- 1. Measure the voltage between test points 1 and 2 individually.

Test condition	OFF mode Each door outer handle 8P connector: disconnected
Test circuit	VOUT_FR_DR
Test point 1	Keyless access control unit connector A (32P) No. 12 (RED)
Test point 2	Body ground
Test circuit	VOUT_FR_AS
Test point 1	Keyless access control unit connector A (32P) No. 21 (RED)
Test point 2	Body ground

Is there battery voltage?

YES

Repair an open or high resistance in the wire.

The VOUT_FR_DR and VOUT_FR_AS wires are OK. Replace the keyless access control unit .
