Control Unit Input Test
WARNING: This page is about a different car, the 2006 Honda Odyssey and 2005 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Before troubleshooting the power tailgate system, troubleshoot the multiplex integrated control system using B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A
).
- Turn the ignition switch OFF.
- Remove the left rear pillar trim (see TRIM REMOVAL/INSTALLATION - PILLAR AREAS ).
- Disconnect the 20P, 14P, and 5P connectors (A) from the power tailgate control unit (B).
- Inspect all the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 5.
- With the connectors still disconnected, make the input tests shown in CONNECTOR INPUT TEST CHART , at the connectors.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If the input tests prove OK, Go to step 6.
CONNECTOR INPUT TEST CHARTCavity Wire Test condition Test: Desired result Possible cause if result is not obtained B3 BRN/WHT Under all conditions Connect B10 terminal to B3 terminal with a jumper wire: The beeper should sound. - Blown No. 7 (7.5 A) fuse in the driver's under-dash fuse/relay box
- Faulty beeper
- An open in the wire
- Reconnect all connectors to the power tailgate control unit, and do the input test shown in CONTROL UNIT INPUT TEST CHART , at the appropriate connector.
- If the test indicates a problem, find and correct the cause, then recheck the system.
- If the input test proves OK, replace the power tailgate control unit.
