Disconnect the battery negative cable, then disconnect
the positive cable, and wait at least three minutes.
Disconnect the driver's airbag connector (see sec-

Driver's Switch:
The driver's switch is combined with the control unit so
you cannot isolate the switch to test it. Instead. run the
master switch input test procedures at terminals 41. A3,
44. A8 and Al2 on page 23-226. lf the tests are normal,
the driver's switch must be faulty.

NOTE: lt is important to maintain the time limits between steps
VALET SWITCH
NOTE: lf the tuner is turned ON, it willgo off and come on again when the reg-
istration procedure is completed-
l-l
NOTE: lf you want to register the codesof more than one transmitter, repeat step4 within 10 seconds with the next trans'mitter.
NOTE: After storing its code, make sure
the transmitter works properly bYrepeatedly pressing one ot its buttons.(The system starts to work when Youpress any transmitter button six times-)
