Where is the Keyless entry module located?

Here is the information we have on the location and replacement instructions for the alarm control module.

The Alarm control module is part of the SJB (smart junction box) behind the left side of the dash.

Cycle a key in ignition to RUN. Enter Security Access on the PATS control function module. Select "Parameter Reset" and then Exit Security Access. Perform a PCM Keep Alive Memory (KAM).

PROCEDURE #8
Cycle a key in the ignition to RUN. Enter Security Access on the PATS control function module. Select "ICM/PCM Parameter Reset." Select "PCM/TCM Parameter Reset" and then Exit Security Access (type F)

ANTI-THEFT

The passive anti-theft system (PATS) consists of the following components:
- Anti-theft indicator
- Encoded ignition key(s) (the key contains a transponder)
- PATS transceiver
- Powertrain control module (PCM)

PATS uses radio frequency identification technology to deter a drive-away theft. Passive means that it does not require any activity by the user.

PATS Function
The PATS function is controlled by the PCM. PATS uses the PCM to carry out all of the PATS functions such as receiving the identification code from the PATS key, controlling the starter and fuel injectors enable, and initiates the key interrogation sequence when the ignition key is turned to the ON or START position. All elements of PATS must be functional before the vehicle will start. If any of the components are not working correctly, the vehicle will not start. If the PCM must be replaced for any reason (PATS concerns or drivability concerns), the PATS keys must be programmed into the new PCM.

PATS is active only for a few seconds when the vehicle is starting. It is not a PATS concern if the vehicle stalls after it has been running for a minimum of 3 seconds. PATS will not disable a running vehicle.

PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from the exterior of the vehicle. These systems may reduce the security of the vehicle, and also may be the cause of no-start concerns. Remote start systems must be removed from the vehicle before any PATS-related no-start concerns are investigated.

PATS will disable the vehicle from starting if there is:
- a damaged PATS key.
- an unprogrammed PATS key.
- a non-encoded key (a conventional key or one that does not have any electronics).
- damaged wiring.
- a damaged transceiver.
- a damaged PCM.

Unlimited Key Mode
PATS contains a feature called unlimited key mode. This feature allows a customer to program more than 8 vehicle keys, if requested. Each vehicle in unlimited key mode is set up with a special unlimited transponder security key code. This allows all the customer vehicles to share the same mechanically cut keys. For an individual customer, any randomly selected security key is acceptable.
