Jeep Cherokee (XJ): General information

Introduction

Power locks are optional factory-installed equipment on this model. The power window system and the power mirror system are included on vehicles equipped with the power lock option. The Remote Keyless Entry (RKE) system is an additional option available on vehicles equipped with the power lock option. Refer to 8W-61 - Power Door Locks in Group 8W - Wiring Diagrams for complete circuit descriptions and diagrams.

NOTE: This group covers both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) versions of this model. Whenever required and feasible, the RHD versions of affected vehicle components have been constructed as mirror-image of the LHD versions.

While most of the illustrations used in this group represent only the LHD version, the diagnostic and service procedures outlined can generally be applied to either version. Exceptions to this rule have been clearly identified as LHD or RHD, if a special illustration or procedure is required.

Power lock system

The power lock system allows all of the doors and the liftgate to be locked or unlocked electrically by operating the switch on either front door trim panel.

This system operates with battery power supplied through a fuse in the junction block, independent of the ignition switch.

The power lock system includes a lock inhibit feature, which prevents the doors from being locked by the power lock system if the driver door is open with the key in the ignition switch or with the headlamp switch in the On position. However, the lock inhibit feature will not prevent manual locking of the vehicle using the manual lock buttons or the key cylinders.

The power lock system includes the front door power lock switches integral to the driver and passenger door modules, and the power lock motors mounted in each door and the liftgate. The power lock control circuitry and the power lock and unlock relays are integral to the Passenger Door Module (PDM).

Following are general descriptions of the major components in the power lock system. Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the power lock system.

Remote keyless entry system

The Remote Keyless Entry (RKE) system is a radio frequency system that allows the use of a remote battery- powered radio transmitter to control the power lock system. On vehicles with the RKE option, the power locks can be operated by depressing the Lock or Unlock buttons of the RKE transmitter. The RKE system includes an illuminated entry feature, which turns on the courtesy lamps for a timed interval (about thirty seconds), when the power locks are unlocked using the RKE transmitter.

The RKE system for this vehicle also features a customer programmable horn chirp feature. This feature allows the customer the option of enabling or disabling the horn chirp request that the RKE receiver issues as an audible indication that a valid Lock signal has been received from the RKE transmitter.

See Remote Keyless Entry Receiver Programming in this group for more information on this feature.

The RKE system can retain the vehicle access codes of up to four transmitters. The transmitter codes are retained in memory, even if the battery is disconnected. If a transmitter is faulty or lost, new transmitter vehicle access codes can be programmed into the system using a DRB scan tool and the proper Diagnostic Procedures manual.

The RKE system consists of the remote key fob transmitter and a radio receiver with program logic.

The RKE receiver is installed in an RKE housing on the headliner of the vehicle, or in the housing of the optional overhead console, depending upon how the vehicle is equipped.

Following are general descriptions of the major components in the RKE system. Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the RKE system.
