Remove the audio unit, then disconnect the A and B connectors (see page 23-189).
Inspect the connector and socket terminals to be sure they are all making good contact
. lf the terminals are bent, loose or corroded, repair them as necessary, and recheck the system
. lf the terminals look OK, make the following input tests at the connector.
- lf anv test indicates a problem, find and correct the cause, then recheck the system
lf all the inout tests prove OK, the control unit must be faulty; replace it.

Transmitter Test
NOTE:
. lf the doors unlock or lock with the transmitter, but

. The doors do not lock or unlock with the transmitter
if the ignition key is inserted in the ignition switch.
1. Using a keyless entry checker (07MAJ - SP003001:
. Place the transmitter on the keyless entry check-
er, and press the transmitter button.
- lf the indicator light does not come on, check
for:- a dead or low batterv- Faulty transmitter- lf the ray indicator light comes on, the trans-
mitter is OK.
