1996 HONDA CIVIC Connector a

Interlock System
Control Unit Input Test
1. Disconnect the 8P connector from the interlock con-trol unit.
2. Inspect the connector and socket terminals to besure they are all making good contact.. lf the terminals are bent, loose or corroded, repairthem as necessary, and recheck the system.. lf the terminals look OK, make the followinginput tests at the connector.- lf a test indicates a problem, find and correctthe cause, then recheck the system.- lf all the input tests prove OK, substitute aknown-good control unit, and recheck the sys-tem. lf the check is OK, the control unit mustbe faulty; replace it.
NOTE: lf the shift lock solenoid clicks when theignition switch is turned ON {ll) and you step on thebrake pedal (with the shift lever in E), the shift locksystem is electronically normal; if the shift leve.cannot be shifted from E], test the Aff gear position
switch, park pin switch, and see section 14.

Key Interlock Solenoid Test
Remove the driver's dashboard lower cover and
knee bolster (see section 20)
Disconnect the 7P connector from the main w're
harness.
3. Check Ior continuity between the terminals in each
kev oosition according to the table'
4. Check that the key cannot be removed with power
and ground connected to the No. 7 and No 6 termi-
nals
. lf the key cannot be removed. the key interlock
solenoid is OK.
. lf the key can be removed, replace the steering
lock assembly (the interlock solenoid is not avail-
able seParatelY).

1, Remove the front console (see section 2Ol.
Disconnect the 4P connector from the park pinswitch.
Check for continuity between the No. 3 and No. 4terminals with:- the shift lever any position other than E, or- the push button pushed in E.There should be continuity.
Check for continuity between the No. 3 and No. 4terminals with the shift lever in E and the push but-ton released. There should be no continuiw. lf nec-essary, replace the park pin switch.
