Checking the component
If the fault is intermittent, it has been registered previously but is no longer present. 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 (PSM)
Check the signal cable between control module terminal #A2 and seat motor 1. Check for an open-circuit. Check for contact resistance.
If a fault is found, replace the signal cable.
Try replacing the motor if no fault is found.
Remedy as necessary.
