Power Locks - Description

DESCRIPTION

POWER LOCKS

The power lock system allows all of the doors to be locked or unlocked electrically by operating a switch on either front door trim panel. When an actuation input signal from the door lock switch, WIN or FOBIK signal is received, the door modules turns on the output drivers a provides a voltage level to the door lock motor for a specified time to lock/unlock the door. Their are two door modules, the Driver Door Module (DDM) and Passenger Door Module (PDM). The door modules have an unswitched battery feed from the TIPM, so the locks can be actuated in any ignition switch position.

The door modules locks the doors automatically when the vehicle is driven beyond the speed of 25.7 km/h (15 mph), all doors are closed and the accelerator pedal is depressed. The rolling door lock feature can be disabled if desired.

This vehicle also offers several customer programmable features, which allows the selection of several optional electronic features to suit individual preferences.

The power lock system for this vehicle can also be operated remotely using the FOBIK.

Certain functions and features of the power lock system rely upon resources shared with other electronic modules in the vehicle over the CAN data bus network. For proper diagnosis of these electronic modules or of the CAN data bus network, the use of a scan tool and the appropriate diagnostic information are required.

AUTOMATIC DOOR LOCKS

When enabled, this feature will lock all of the door locks if all of the doors are closed and the vehicle speed goes above 25.7 km/h (15 mph). If a door unlock has occurred, then the door modules will perform another auto lock, if the doors did not electrically unlock, another auto lock will not occur.

DOOR LOCK INHIBIT

When the FOBIK is in the ignition (in any switch position) and either front door is opened, the door lock switches LOCK functions are disabled. The UN-LOCK functions are still functional. This protects against locking the vehicle with the FOBIK still in the ignition. The FOBIK will still lock the doors. After the FOBIK is removed from the ignition or the doors are closed, the power door locks will operate normally.

REMOTE KEYLESS ENTRY

A Radio Frequency (RF) type Remote Keyless Entry (RKE) system is an available factory-installed option on this model. The RKE system allows the use of a remote battery-powered radio transmitter to signal the Wireless Ignition Node (WIN) to actuate the power lock system. The WIN operates on non-switched battery current through a fuse in the Totally Integrated Power Module (TIPM), so that the system remains operational, regardless of the ignition switch position.

The FOBIK transmitters are also equipped with a Panic button. If the Panic button on the FOBIK transmitter is depressed, the horn will sound and the exterior lights will flash on the vehicle for about three minutes, or until the Panic button is depressed a second time. A vehicle speed of about 25.7 km/h (15 mph) will also cancel the panic event.

The RKE system can also perform other functions on this vehicle. If the vehicle is equipped with the optional Vehicle Theft Security System (VTSS), the FOBIK transmitter will arm the VTSS when the Lock button is depressed, and disarm the VTSS when the Unlock button is depressed.

The RKE system includes two transmitters when the vehicle is shipped from the factory, but the system can retain the vehicle access codes of up to a total of eight transmitters. The transmitter codes are retained in the WIN memory, even if the battery is disconnected. If an FOBIK transmitter is faulty or lost, new transmitter vehicle access codes can be programmed into the system using a scan tool, Programming and Relearning.

This vehicle also offers several customer programmable features, which allows the selection of several optional electronic features to suit individual preferences. Customer programmable feature options affecting the RKE system include:

- Automatic Door Lock - Customer programmable feature that allows the TIPM to perform an automatic door lock if the vehicle speed is above 25.7 km/h (15 miles-per-hour).
- Automatic Door Unlock On Exit - Customer programmable feature that allows the TIPM to perform an automatic door unlock if the vehicle speed is 0, vehicle in park and driver door is opened.
- Flash Lights with Lock and Unlock - Allows the option of having the park lamps flash as an optical verification that the RKE system received a valid Lock request or Unlock request from the FOBIK transmitter, or having no optical verification.
- Programming Additional Transmitters - Allows up to a total of eight transmitter vehicle access codes to be stored.
- Remote Unlock Sequence - Allows the option of having only the driver side front door unlock when the FOBIK transmitter Unlock button is depressed the first time. The remaining doors unlock when the button is depressed a second time within 5 seconds of the first unlock press. Another option is having all doors unlock upon the first depression of the FOBIK transmitter Unlock button.
- Sound Horn on Lock - Allows the option of having the horn sound a short chirp as an audible verification that the RKE system received a valid Lock request from the FOBIK transmitter, or having no audible verification.

Certain functions and features of the RKE system rely upon resources shared with other electronic modules in the vehicle over CAN data bus network. For diagnosis of these electronic modules or of the CAN data bus network, the use of a scan tool and the appropriate diagnostic information are required.
