Controller Input Test
NOTE: 8e careful not to damage the controller and the
instrument panal.
1. Remove the instrument panel lrom the dsshboard
{see page 23-1181.
2. Remove the dash lights b.ightness controller {rom
the dashboard. then disconnect the 3-P connector.
Inspect the connector and socket terminals to be
sure they are all making good contact.
a lf the terminals are bent. loose o. corroded, repsir
them as necessary, and recheck the system.
a It the terminals look OK, make the tollowing in-
Dut tests at the connector.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.- lf all the input tests prove OK, the dash lights
brightness controller must be faulty; replace it.

Manual Transmigsion:
NOTE: Check the No. 1 5 { 1 O A) fuse in the under-dash
fuse/relay box befote testing.
'1. Test the back-up light switch by placing the shift
lever in reverse and turning the ignition switch to ON
(

).
2. It the back-up lights do not go on, check the back-
up light bulbs in the taillight assembly.
3. lf the tuse and bulbs are OK. disconnect the connec-
tor from the back-up light switch.

4. With the shift lever in reverse. check Jor continuity
between the A and B terminals with the switch in-

There should be continuity.
a lf there is no continuity, replace the switch {see
section 13).

Automatic Transmission:
NOTE: Check the No. l 5 ( 1 O A) fuse in the under-dash
fuse/relay box belore testing.
1. Test the back-up light switch by shitting the shift
lever to l3l and turning the ignition switch ON (ll).
2. lf the back-up lights do not go on, check the back-
up light bulbs in the taillight assembly.
3. lf the tuse and bulbs are OK, disconnect the 14-P
connector from the A/T gear position switch (back-
up light switch).
Move the lever back and torth at the LBI position
without touching the push button, and check tor
continuitv between th€ C and D terminals. There
should be continuitY within the range of free plsy of
the shift lever.
a lf there is no continuity within the range oJ J.ee
play, adjust the position ot the A/T gear position
