How to Perform Trouble Diagnoses for Quick
and Accurate Repair
NLBR0094INTRODUCTIONNLBR0094S01The ABS system has an electronic control unit to control major
functions. The control unit accepts input signals from sensors and
instantly drives actuator. It is essential that both kinds of signals are
proper and stable. It is also important to check for conventional
problems: such as air leaks in the booster or lines, lack of brake
fluid, or other problems with the brake system.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or faulty wiring. In this case,
careful checking of suspicious circuits may help prevent the
replacement of good parts.
A visual check only may not find the cause of the problems, so a
road test should be performed.
Before undertaking actual checks, take just a few minutes to talk
with a customer who approaches with a ABS complaint. The cus-
tomer is a very good source of information on such problems;
especially intermittent ones. Through the talks with the customer,
find out what symptoms are present and under what conditions
they occur.
Start your diagnosis by looking for“conventional”problems first.
This is one of the best ways to troubleshoot brake problems on an
ABS controlled vehicle. Also check related Service Bulletins for
information.

Preliminary CheckNLBR0095
1 CHECK BRAKE FLUID LEVEL
Check brake fluid level in reservoir tank.
Low fluid level may indicate brake pad wear or leakage from brake line.
NBR376
Is brake fluid filled between MAX and MIN lines on reservoir tank and/or has brake fluid been contaminated?
Ye s©GO TO 2.
No©Repair. GO TO 2.
2 CHECK BRAKE LINE
Check brake line for leakage.
SBR389C
Is leakage present at or around brake lines, tubes or hoses or are any of these parts cracked or damaged?
Ye s©GO TO 3.
No©Repair. GO TO 3.
