2. INSPECT SHIFT LOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal 1 and 2.
Standard resistance: 21 - 27 W
If the resistance value is not as specified, replace the solenoid.
(c) Apply the battery positive voltage between terminals.
Check that the operation noise can be heard from the so-
lenoid.
If the solenoid does not operate, replace the solenoid.
3. INSPECT SHIFT LOCK CONTROL SWITCH
Inspect that continuity exists between each terminal.

TROUBLESHOOTING
1. DIAGNOSIS FUNCTION (Main AVC-LAN)
(a) Diagnosis start-up
For shifting to diagnosis mode, turn the ignition switch ON and push the ºDISCº switch 3 times while
pressing ºch1º and ºch6º switches.
HINT:
To exit the diagnosis mode, push the ºDISCº switch for 1.7 sec. or turn the ignition switch to ACC or OFF.
(b) Element check mode
After the diagnosis start-up, the system enters the element check mode. Check that the all elements
light up.
HINT:
By pressing the ºTUNE UPº switch, the system enters the ºService Check Modeº.
(c) Switch check mode
(1) Element check mode is started at the same time with the switch check mode.
(2) Check that there is a beep sound when any switch is pressed.
HINT:
By pressing ºTUNE UPº switch, the system enters the ºService Check Modeº.
