\lgnition Key Switch Test
NOTE: For more key-in beeper information, refer to the
circuit diagram (see page 22-90) and input test (see
page 22-921.
When the ignition key is in the ignition switch the
multiplex control unit senses ground through the
closed ignition key switch. When you open the driver's
door, the multiplex control unit senses ground through
the closed door switch and sounds the beeper.
1. Remove the steering column upper and lower
covers (see page'17-9).
2. Disconnect the 6P connector.
3.Check for continuity between the No. 1 and No. 2
termrnars.
. There should be continuity with the key in the
ignition switch.. There should be no continuity with the key
removed from the ignition switch.
lf the continuity is not as specfied, replace the
ignition switch.
