Fault In Memory Position
Memory position fault
Checking function of the memory button
- Ignition OFF.
Select scrolling values and read off the value for memory button 3 and MEM.
Press in the programming button MEM and keep it pressed while pressing memory storage button 3.
MEM and memory button 3 status should change from NOT ACTIVE to ACTIVE when the respective button is pressed in.
OK - Checking memory function 3
Not OK - Connecting the break-out box
-------------------------------------------------
Checking memory function 3
Operate the seat so it moves to a new position using the control buttons.
Activate stored memory position 3 to see if the seat moves to that position.
Does the seat move to memory position 3?
Yes - Fault-tracing information
No - Replace component
-------------------------------------------------
Fault-tracing information
The diagnostic trouble code (DTC) was probably set because no position has been programmed into memory position 3.
Press "Continue".
Continue - FAULT FOUND
-------------------------------------------------
Replace component
The diagnostic trouble code (DTC) was probably set due to an internal fault in the control module.
Try a new control module according to Control module, replace Control Module.
Press "Continue" when the fault has been remedied.
