Switch, Heated Seat: Operation: Operation

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

When either of the heated seat switches located in the U-Connect Touch ™ screen module are pressed with the engine running, a signal is sent to the Heated Seat Module (HSM) (also know as the comfort seat wheel module) over the Controller Area Network (CAN) data bus, signaling the module to energize the heating elements for the selected seat. Indicator lamps illuminate for each heated seat switch and indicate the level of heat in use (HI or LO). Pressing a heated seat switch once will select high-level heating and pressing the same switch a second time will select low-level heating. Pressing the switch a third time will shut the heating elements off.

The HSM energizes the integral solid-state relays that supply battery current to the heating elements. When high-temperature level heating is initially selected, the HSM provides a boosted high-heat level during the first four minutes of operation. After the first four minutes have passed, the HSM then drops the heat output to the normal high-temperature level for the next 26 minutes of operation. During high-temperature level operation, the HI indicator illuminates in the switch. After 30 minutes of high-temperature level heating, the HSM automatically lowers the heat level to low. At that time, the LO indicator illuminates. Operation on the low-temperature level setting will automatically turn off after 30 minutes.

The individual heated seat switches located in the U-Connect Touch ™ screen module cannot be adjusted or repaired. If a heated seat switch or indicator lamp is inoperative or damaged, the entire U-Connect Touch ™ screen module must be replaced. Refer to REMOVAL .
