Incomplete Power Open - Excessive Hall Effect Signal

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. 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 from stop to stop if possible. With the DRBIII®, read ACTIVE DTCs. If the DRBIII®, displays INCOMPLETE POWER OPEN - EXCESSIVE HALL EFFECT SIGNAL, go to the next step. If the DRBIII®, does not display INCOMPLETE POWER OPEN - EXCESSIVE HALL EFFECT SIGNAL, inspect the wiring and connectors for an intermittent condition. Operate the door several times and check for any binding conditions.
  2. 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.
  3. Examine the Lower Drive Unit for alignment and gear condition. Manually operate the sliding door and observe the gear and track. If the Lower Drive Unit and Track is in good condition, go to the next step. If the Lower Drive Unit and Track is not in good condition, replace the Lower Drive Unit and Track as necessary. See POWER SLIDING DOORS & LIFTGATE article.
  4. Operate the door from the full closed position and put an obstacle in it's path to make it reverse. If the door reversed back to the closed position, go to the next step. If the door did not reverse back to the closed position, replace the Power Sliding Door Module. See POWER SLIDING DOOR MODULE  under REMOVAL & INSTALLATION.
  5. Disconnect the Sliding Door Motor connector. See Figure. Using a 12-volt test light connected to 12-volts, check the Ground circuit. If the test light illuminates brightly, go to the next step. If the test light does not illuminate brightly, repair the hall effect ground circuit for an open.
  6. Disconnect the Sliding Door Motor connector. See Figure. Disconnect the Sliding Door Control Module C2 connector. See Figure or Figure. Measure the resistance of the Door Motor Hall Effect Supply circuit between the Sliding Door Motor connector and the PSD Module C2 connector. If the resistance is below 5 ohms, go to the next step. If the resistance is above 5 ohms, repair the Door Motor Hall Effect Supply wire for an open.
  7. Disconnect the Sliding Door Motor connector. See Figure. Disconnect the Sliding Door Control Module C2 connector. See Figure or Figure. Measure the resistance between ground and the Door Motor Hall Effect Supply circuit. If the resistance is below 100 ohms, repair the Door Motor Hall Effect Supply wire for a short to ground. If the resistance is above 100 ohms, go to the next step.
  8. Disconnect the Sliding Door Motor connector. See Figure. Disconnect the Sliding Door Control Module C2 connector. See Figure or Figure. Measure the resistance of the Door Motor Hall Effect Signal circuit between the Sliding Door Motor connector and the PSD Module C2 connector. If the resistance is below 5 ohms, go to the next step. If the resistance is above 5 ohms, repair the Door Motor Hall Effect Signal wire for an open.
  9. Disconnect the Sliding Door Motor connector. See Figure. Disconnect the Sliding Door Control Module C2 connector. See Figure or Figure. Measure the resistance between ground and the Door Motor Hall Effect Signal circuit. If the resistance is below 100 ohms, repair the Door Motor Hall Effect Signal wire for a short to ground. If the resistance is above 100 ohms, go to the next step.
  10. If there are no possible causes remaining, replace the Power Sliding Door Motor Assembly (Hall Effect Switch). See POWER SLIDING DOORS & LIFTGATE article.
