1. Power Sliding Door Malfunction 2. Power Sliding Door Open/Close Switch Inoperative |
The body control module (BCM) and the left and right power sliding door modules (PSDM) monitor the battery voltage through the B+ circuit. Damage to components and incorrect data may occur when the voltage is out of range.
Battery voltage must be less than 9 volts or greater than 15.9 volts.
While attempting the power sliding door OPEN or CLOSE command, the PSDM detects the power sliding door (PSD) system voltage is below 9 volts or above 15.9 volts for greater than 5 seconds.
The power sliding door(s) will be inoperative
• | The DTC will be current for as long as the fault is present. |
• | When the fault is no longer present, the DTC will be a history DTC. |
• | A history DTC will clear after 50 ignition cycles. |
DTC B1292, B1293, B1294, B1395, B1420, B3250, B3260 or any combination of these DTCs may be set due to an overcinch condition in which the sliding door motor may continue to run for up to 3 seconds after the door is fully closed. Reference any power sliding door overcinching bulletins first before performing any extensive power sliding door diagnostics.

Power Sliding Door (PSD) Description and Operation
Ignition ON, observe the scan tool Battery Voltage Signal parameter while commanding the power sliding door to OPEN and CLOSE by using the power sliding door switch. The parameter should be between 9.6-13.6 volts.
