YES 

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

NO 

Repair an open or high resistance in the wire.

-1. Remove the jumper wires from the door outer handle connectors.

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

Is there continuity?

YES 

Repair a short to ground in the wire.

NO 

The TS FRDR and TS FRAS wires are OK. Go to step 6.

Is the system OK?

YES 

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

NO 

Replace the keyless access/TPMS control unit .

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

Is there battery voltage?

YES 

Repair an open or high resistance in the wire.

NO 

The VOUT FRDR and VOUT FRAS wires are OK. Replace the keyless access/TPMS control unit .
