Modus Massage Seat Failure

Massage seat not working? That's a new one. It could be the wiring, but did you check the fuse box? Is there a fuse for the seats or massage setting? Maybe it's something simple before tearing into the seat.

Which specific fuse location should I inspect? Is it in the engine compartment or in the passenger compartment?

I'm not sure where your Modus has the fuse box. It should be in the owner's manual. If you've checked the fuses and it's not that, and you're getting an error code, maybe take it to a workshop. They can properly diagnose the electrical issue.

I took the car to a workshop. The cable connection to the massage unit was defective. Your input helped confirm the probable cause, thanks.
