A/T Gear Position Indicator
Indicator Input Test
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (24) before performing repairs or ser-
vice.
Remove the dashboard lower cover, dashboard lower
pad and instrument panel. Disconnect the connector
“A” 130-P) from the gauge assembly (see page 23-127
(’93-’96) (’91-’92)).
Inspect the connector and socket terminals to be sure
they are all making good contact.
If the terminals are bent, loose, or corroded, repair
them as necessary, and recheck the system.
If the terminals look OK, make the following input
tests at the connector.
— If a test indicates a problem, find and correct the
cause, then recheck the system.
— If all the input tests prove OK, the control unit
must be faulty; replace it.
