B0501 Passenger Power Window Circuit Malfunction

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

For B0501 neither the reachable J2012 lists nor any manufacturer offer a definition, so the code is unverified. The title points to the front passenger window circuit. Saab's 9-3 passenger door module uses B3205/B3210 for its own motor paths and B3932 when it measures current while the motor should be idle; one-touch travel then stops. GM's 2011 9-4X sets B3210 for the passenger motor if its compatibility code does not match the BCM. Honda's US7145299B2 shows the classic layout in which the driver's master switch commands the passenger door over a single line, so the fault may sit in the master switch, the line or the local switch. Without working reversal, FMVSS 118's 100 N limit rules out automatic closing. The passenger switch circuit is B0247.

Likely causes

Passenger window motor worn or internally faulty
Passenger button in the driver's master switch faulty
Wiring broken in the passenger door hinge passage
Replacement motor not coded or not matched to the body module

Symptoms

  • Passenger window dead from both the local and the master switch
  • Window works only while the button is held
  • Window moves slowly or stops partway
