Ignition Key Switch Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Honda Odyssey, 2003 Honda Odyssey, 2002 Honda Odyssey, 2001 Honda Odyssey, and 2000 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For more key-in beeper information, refer to the circuit diagram (see CIRCUIT DIAGRAM ) and input test (see CONTROL UNIT INPUT TEST ).

When the ignition key is not removed, the key-in beeper in the driver's multiplex control unit senses ground through the closed ignition key switch. When you open the driver's door, the beeper circuit senses ground through the closed door switch.

Remove the steering column upper and lower covers (see STEERING COLUMN REMOVAL AND INSTALLATION ).
Disconnect the 7P connector.
NOTE: Lock tab (A) points down when installed.

Check for continuity between terminals No. 1 and No. 3.
- There should be continuity with the key in the ignition switch.
- There should be no continuity with the key removed.
If the continuity is not as specified, replace the ignition key switch.
