Control panel




There are two different types of control panel:
- for power seats without memory
- for power seats with memory.
Power seats without memory
In cars with power seats without memory, the control panel is directly connected to the motors and does not have a power seat module (PSM).
Power seats with memory
In vehicle with power seats with memory, the control panel is integrated in the power seat module (PSM).
An easy way of differentiating between power seats with memory and power seats without memory is to look at the control panel. Seats without memory do not have memory buttons (1-3) or a programming button (MEM).
This information refers to seats with memory (power seat module (PSM)) unless otherwise stated.
The controls are used to transmit input signals to the control module from the user:
- Runs each of the four motors in the direction required
- Memory buttons. Input signal indicating the position of the buttons (Memory 1, 2 and 3 and the programming button).
The control panel cannot be replaced separately. The entire control module must be replaced if there is a fault.
There are diagnostics for the control panel.
