Maintenance Reminder Unit Input Test
1.With the ignition switch OFF, disconnect the 5-P
connector from the reminder unit,
Inspect the connector and socket terminals to be
sufe they are all making good contact.
a lJ the terminals are bent, loose orcorroded, repair
them as necessary, and recheck the svstem.
a It the terminals look OK, make the following in-
Put tests at the connecto..- lf a test indicates a problem, tind and correct
the cause, then recheck the system.- It allthe input tests prove OK, the reminder unit
must be taulty; replace it.

a The numbers in the table show the troubleshooting sequence.
a Before troubleshooting,- check the No.15 {10 A) and *No. 24 fuses in the under-dash fuse/relay box, and the No.41 (1OO A), No.39(50 A). and No.42 (20 Al fuses in the under-hood fuse/relav box.- check that the horn sounds.
check the tachometer to see if it wo.ks pfoperly.
*No. 24 {15 A): Bl8B1 engine
No. 24 {2O A}: 818C1 engine
