1994 HONDA INTEGRA brake

Control Unit Input Test
Oisconnect the 8-P connector from the interlock control
unit. Check for good contact between the connector and
socket terminals. lf the terminals 8re OK, make Iollow-
ing input tests at the connector. lf all input tests are OK,
but the problem remains, replace the cont.ol unit,
NOTE: lf the shilt lock solenoid clicks when the ignition
switch is ON and the brake pedal is pushed (shift tever
is in lfl position, accelerator is in rest position), the shiftlock system is electronically normal; test the A/T gear
positaon switch as described on page 23- 134.

Brake Switch Test
lf the brake lights do not go on, check the No. 42
{2O A) fuse in the under-hood fuse/relay box, and
the brake light bulbs in the taillighr assembly and high
mount brake light.
lf the fuse and bulbs are OK. disconnect the 2-P or
4-P connector {rom the brake switch.
3. Check fo. continuitv between the B and C terminals.
There should be continuity with the brake pedal
pushed.
a lJ there is no continuitv, replsce the switch or ad-
just pedal height {see section 19).
a lf there is continuity, but the brake lights do not
go on, inspect for:- Poor ground (G5O3)
