Incomplete Power Open - Overcurrent
NOTE:
After making any repairs, perform BODY VERIFICATION TEST under VERIFICATION TESTS.
- With the DRBIII®, record and erase DTC's. Turn the ignition off, wait 10 seconds, then turn the ignition on. Operate the power sliding door several times if possible. With the DRBIII®, read DTCs. If the DRBIII® displays INCOMPLETE POWER OPEN - OVERCURRENT, go to the next step. If the DRBIII® does not display INCOMPLETE POWER OPEN - OVERCURRENT, inspect the wiring and connectors for an intermittent condition. Operate the door several times and check for any binding conditions.
- Examine the door for proper fit and alignment, loose/hard or torn seals, worn teeth on the track and gear (lower drive unit) or anything that would cause an obstruction to proper operation. Manually operate the sliding door on the other side or of a known good vehicle and notice the effort needed to open and close. Compare the effort needed on the disabled door. If it takes more effort to operate the door than it should, see POWER SLIDING DOORS & LIFTGATE article. If sliding door effort is not excessive, go to the next step.
- Turn the ignition off. Disconnect the Sliding Door Control Module C1 connector. See Figure or Figure. Using a 12 volt test light connected to 12-volts, check the Ground circuit. Wiggle the harness and check for an intermittent open condition. If the test light illuminates brightly, go to the next step. If the test light does not illuminate brightly, repair the Ground circuit for an open.
- Turn the ignition off. Disconnect the Sliding Door Control Module C1 connector. See Figure or Figure. Measure the resistance between ground and the Sliding Door Open Driver circuit. Wiggle the harness and check for an intermittent short circuit condition. If the resistance is below 1000 ohms, repair the Sliding Door Open Driver circuit for a short to ground. If the resistance is above 1000 ohms, go to the next step.
- Turn the ignition off. Disconnect the Sliding Door Control Module C2 connector. See Figure or Figure. Measure the resistance between the Cinch/Release Motor Latch Driver circuit and the Cinch/Release Motor Unlatch Driver circuit. Wiggle the harness and check for an intermittent open condition. If the resistance is below 2 ohms, go to the next step. If the resistance is above 2 ohms, repair the Cinch/Release Motor Latch Driver circuit for an open.
- Turn the ignition off. Disconnect the Sliding Door Control Module C2 connector. See Figure or Figure. Measure the resistance between ground and the Cinch/Release Motor Latch Driver circuit. Wiggle the harness and check for an intermittent short condition. If the resistance is below 100 ohms, repair the Cinch/Release Motor Latch Driver circuit for a short to ground. If the resistance is above 100 ohms, go to the next step.
- Turn the ignition off. Disconnect the Sliding Door Control Module C2 connector. See Figure or Figure. Measure the resistance between ground and the Door Motor Clutch Driver circuit. Wiggle the harness and check for an intermittent short condition. If the resistance is below 100 ohms, repair the Door Motor Clutch Driver circuit for a short to ground. If the resistance is above 100 ohms, go to the next step.
- If there am no possible causes remaining, replace the Power Sliding Door Motor/Clutch assembly. See POWER SLIDING DOORS & LIFTGATE article.
