Wear safety glasses before servicing heated seat switch operations to protect from possible air bag incident injuries. Live side air bag modules should be handled by keeping the air bag and tear seam pointed in a direction that is away from your body at all times. It is prohibited to place a live module down on the cover tear seam during handling. Sodium hydroxide residue requires hand washing with soap and water after experiencing an air bag deployment. Probing the connectors through the air bag module leads to unwanted deployment of the system. Proper vehicle sensor alignment must be checked and the sensor mounting bracket along with wiring pigtail requires inspection for any signs of damage after a collision. All damaged SRS components need replacement regardless of air bag deployment. The technician must disconnect the ground cable from the battery while waiting at least one minute to drain back up power along with disconnecting any extra batteries when present. The restraint system diagnostic tool functions solely for service operations so it needs removal prior to vehicle driving. The diagnostic tool must be connected into the side air bag connector located at the floor connector to conduct side air bag system and safety belt pretensioner diagnostics. The diagnostic process needs to be restarted after reinstalling the original part if the problem remains unresolved. When side air bags activate the seatback pad along with trim cover and side air bag module should get replaced and seatback frame installation might become necessary. Start the removal procedure by disconnecting the ground cable of the battery before moving on to remove the seat control switch knob followed by the front seat cushion side shield and seat backrest handle and their associated screws and shield and electrical connector disconnections. First free the locking tab before extracting the heated seat switch then reinstall by following the previous steps backward.

The first step when servicing the heated seat switch requires power drain safety procedures with the pending of battery discharge through negative cable separation followed by a one-minute waiting period and optional power supply detachment from auxiliary batteries and power systems. It is essential to wear safety glasses when servicing air bag systems because they protect from potential injuries. Start by taking out the recliner handle cover along with the outboard front seat side cushion shield laterally before you remove screws from each side of the passenger seat and sliding the shield as needed. To begin the procedure disconnect the heated seat switch electrical connector together with the seat control switch electrical connector (if present). The heated seat switch needs to be extracted from its position. The process ends with a return of all removal steps followed by powering up the supplemental restraint system keeping in mind all safety instructions to prevent personal injury.

Reverse the removal steps and repower the system.

Always wear safety glasses to protect against injury from accidental air bag deployment.

Avoid probing the connectors on the air bag module.

Disconnect the battery ground cable and wait at least one minute to deplete the backup power supply, ensuring that any auxiliary batteries are also disconnected.

Replace the seatback pad, trim cover, and side air bag module, and install a new seatback frame if necessary.

Reverse the removal procedure.
