Removal & Installation

WARNING: This page is about a different car, the 2002 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect and isolate the battery negative cable. Remove the driver side front bucket seat from the power seat track unit.
  2. Lift the heated seat module off of the power seat track and disconnect the power seat wire harness connectors. Remove the module from the bracket.
  3. Install the MHSM/HSM into the bracket. Position the heated seat module and mounting bracket onto the power seat track. Reconnect the power seat wiring harness connectors to the heated seat module.
  4. Install the driver side front bucket seat onto the power seat track unit. Reconnect the battery negative cable.
  5. If the vehicle is equipped with the optional memory system, following installation, it will be necessary to initialize the Memory Heated Seat Module (MHSM). In order to function properly, the MHSM must learn the sensor values of each of the power seat motor position transducers in each of the adjuster hard stop positions. This is done by performing the Reset Guard Band procedure. See RESET GUARD BAND  under PROGRAMMING.
