Honda keyless issues

This TSB applies to 2013 Honda Accords and Crosstour models. Either one or both keyless remotes do not lock or unlock the doors, or the engine will not start unless the remote is placed very close to the engine start/stop button.

The probable cause is faulty keyless access control unit software. The corrective action involves replacing the keyless access control unit.

NOTE: Before replacing the keyless access control unit, you must have all of the customer’s keyless remotes. If not, all missing remotes will have to be registered during a subsequent repair.

Try to unlock the vehicle doors with the keyless remote (make sure that the battery in the remote is good by checking the LED operation), and try to start the engine with the keyless remote in your pocket. If the engine will not start, place the keyless remote close to the engine start/stop button and try to start again.

• If you can lock/unlock the vehicle doors with the keyless remote and start the engine with the keyless remote in your pocket, this bulletin does not apply. Continue with normal troubleshooting.

• If you cannot lock/unlock the doors or start the engine unless the keyless remote is very close to the start/stop button, go to the repair procedure.

REPAIR PROCEDURE

1. Remove the driver’s dashboard lower cover. Loosen the bottom clips first and slowly work your way up. Disconnect the ECON connector. Disconnect the VSA OFF switch connector. Disconnect the TPMS switch connectors (except Touring). Disconnect the LDW switch connector.

2. Remove the keyless access control unit.

• Remove the harness clip.

• Remove the junction box clip.

• Disconnect the keyless access control unit connectors.

• Remove the keyless access control unit from the steering hanger beam.

3. Remove the keyless access control unit from the bracket.

REGISTER THE NEW CONTROL UNIT

NOTE: Do not exit or interrupt the registration process once it has begun. Take your time and follow the screen prompts carefully.

Connect a battery booster to the vehicle’s battery. Be sure to have only one remote in the vehicle at a time during registration. All other remotes to be programmed must be kept at least six feet away from the vehicle.

1. Connect the HDS to the vehicle. Click on “Select a new vehicle” and follow the screen prompts. The ignition will not turn on until the HDS commands it to.

2. When prompted “Is the 3 or 5 pin DLC adapter fitted to the DLC cable?”, select NO.

3. When prompted “Does this vehicle have a KEYLESS ACCESS remote, One Push Start system?” select YES. Note: The first attempt at turning the ignition ON will fail. This is normal. Continue to follow the screen prompts.
