Pin21 should only be available on the passenger seat, but my driver’s seat also has pin21, which caused the module to be confused.
Thank you for your help
It is not possible to fit the passenger seat to driver side! (seat belt and the controller button are on the opposite sides)
Second, according to wiring diagrams, there is no PIN21 on either side. The passenger side has 4/240 OCCUPANT WEIGHT SENSOR OWS which is connected to 94/506:31 (LIN) and 94/506:17 (IGN_KL15) . The driver side seat does not have this module! The connector (94/506) is the big black connector under the seat that is connected to the car's harness. :31 and :17 are the PIN numbers on that connector.
So, most likely as mentioned before, someone install a PSMP (passenger side seat control module) to the driver seat.
Or, if your seats came from right hand drive car, you might be able to switch the controllers. It's easy to find out.
Disconnect the passenger side seat's connector.
Connect the Orbit and try to get ECU parts numbers from the PSMD (driver side module) under ECU tools. If it does not respond to PSMD, then try with PSMP. Then you know.
