Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Power reduction of seat heating
The energy management system in the vehicle can activate the seat heating at a reduced power level corresponding to the vehicle's energy balance. The energy management is located in the digital engine-control system.
The digital engine control sends the request to reduce power via the PT-CAN. The central gateway transfers the information to the KCAN. This allows the seat module to receive the request to reduce power.
The reduction stages are:
- Operation of seat heating in Stage 2
- Operation of seat heating in Stage 2 at only 50%
- Seat heating OFF.
During a starting cycle (terminal 50 ON) or when the seat adjustment switch is operated, the seat module prevents the seat heating from functioning. The LED indicator for the activated seat heating remains lit.
