Circuit Description
The rear side door actuator control module uses an optical sensor to monitor the sliding door position at all times. The optical sensor requires a 5 volt reference and reference return from the rear side door actuator control module. There are 2 signal circuits from the optical sensor to the rear side door actuator control module. The optical sensor sends pulses through both signal circuits to the power sliding door module whenever the sliding door is in motion. The optical sensor pulses allow the rear side door actuator control module to calculate the position of the sliding door at all times. The optical sensor signal circuits switch from 0.01 to 4.5 volts as the sliding door is moving.
Conditions for Running the DTC
A DTC 13 may be set whenever the sliding door is in motion.
Conditions for Setting the DTC
The optical sensor input to the rear side door actuator control module indicates that the sliding door is out of its normal operating range.
Action Taken When the DTC Sets
The rear side door actuator control module sets DTC 13.
Conditions for Clearing the DTC
All stored DTCs are cleared whenever the on-board diagnostic modes are exited.
Diagnostic Aids
| • | Inspect the optical sensor connector and terminals for damage. |
| • | Inspect the optical sensor pigtail harness for damage. |
| • | Inspect the optical sensor for proper installation and a secure mount to the actuator motor housing. |
Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
-
Tests the rear side door actuator control module for the optical sensor 5 volt reference and ground.
-
Tests the optical sensor signal circuit. While the door is moving at the approximate power operating speed the average voltage measured should be 2 to 3 volts.
-
Tests the optical sensor signal circuit. While the door is moving at the approximate power operating speed the average voltage measured should be 2 to 3 volts.
