INTRODUCTION

The ABS system hasanelectronic controlunittocontrol major
functions. Thecontrol unitaccepts inputsignals fromsensors
and instantly drivestheactuators. Itis essential thatboth kinds
of signals areproper andstable. Itis also important tocheck
for conventional problems:suchasair leaks inbooster lines,
lack ofbrake fluid,orother problems withthebrake system.

SEF233G
Itis much moredifficult todiagnose aproblem thatoccurs
intermittently ratherthancontinuously. Mostintermittent prob-
lems arecaused bypoor electric connections orfaulty wiring.
In this case, careful checking ofsuspicious circuitsmayhelp
prevent thereplacement ofgood parts.
A visual checkonlymaynotfind thecause ofthe problems, so
a road testshould beperformed.
Before undertaking actualchecks, takejustafew minutes to
talk with acustomer whoapproaches withaABS complaint. The
customer isavery good source ofinformation onsuch prob-
lems; especially intermittent ones.Through thetalks withthe
customer, findoutwhat symptoms arepresent andunder what

SEF234G
conditions theyoccur.
Start yourdiagnosis bylooking for"conventional" problems
first. Thisisone ofthe best ways totroubleshoot brakeprob-
lems onanABS controlled vehicle.

SYMPTOM: Longstopping distance

Disconnect ABSrelay box6-pin connec- No
tor and check whether stopping dis-
tance isstill long.
Perform Preliminary Checkandair
