The driver door module (DDM) and passenger door module (PDM) check for hall sensor pulses of their respective window motors at least once every 50 milliseconds. When the DDM or PDM detects no hall sensor pulses in the window motor, a DTC is set.
Battery voltage must be between 9-16 volts.
• | The DDM or PDM detects no hall sensor pulses from the power window motor. |
• | A RAM memory check error has been detected. |
• | A window lifter motor error has been detected. |
• | Under/overrun of position counter detected. |
No window express modes are possible.
• | The condition responsible for setting the DTC no longer exists. |
• | You issue a scan tool CLEAR DTCs command. |
The following conditions may cause an intermittent malfunction:
• | An intermittent sticking or binding window causing excessive current draw resulting in a critical temperature fault. |
• | A window motor is shorted internally. |
