Signal missing

Checking the component
If the malfunction is intermittent, it means that the malfunction has been registered at an earlier time but the malfunction no longer remains. Intermittent faults can occur for a number of different reasons. The fault is evaluated depending on how it occurs.
Check the fuse for the power seat module, left (PSL).
Check the signal cable between control module terminal #A4 and seat motor 3. Check for an open-circuit. Check for contact resistance.
Replace the signal cable if a fault is found.
Try replacing the motor if no fault is found.
Remedy as necessary.
