Abs Troubleshooting - Suzuki SV650 Supplementary Service Manual

ABS TROUBLESHOOTING

ABS TROUBLESHOOTING DESCRIPTION
Many of the ABS malfunction diagnosing operations are performed by checking the wiring continuity. Quick
and accurate detection of malfunctions within the complex circuitry assures the proper operation of the ABS.
Before beginning any repairs, thoroughly read and understand this Supplementary Service Manual.
The ABS is equipped with a self-diagnosis function. The detected malfunction is stored as a diagnostic trou-
ble code which causes the ABS indicator light to light up or flash in set patterns to indicate the malfunction.
Diagnostic trouble codes are stored even when the ignition switch is turned to OFF and they can only be
erased manually. In order to repair the ABS correctly, ask the customer for the exact circumstances under
which the malfunction occurred, then check the ABS indicator light and the output diagnostic trouble codes.
Explain to the customer that depending on how the motorcycle is operated (e.g., if the front wheel is off the
ground), the ABS indicator light may light up even though the ABS is operating correctly.
ABS OPERATION AND ABS INDICATOR LIGHT
The ABS indicator light shows the ABS operating condition. Dur-
ing normal operation, the ABS indicator light lights up when the
ignition switch is turned to ON and goes off after the motorcycle
is ridden at more than 5 km/h (3.1 mile/h). If a malfunction has
occurred, the ABS indicator light keeps lighting up.
The ABS indicator light goes off when the motorcy-
cle is ridden at more than 5 km/h (3.1 mile/h).
The ABS indicator light keeps lighting up even
though the motorcycle is ridden at more than 5 km/h
(3.1 mile/h).
The ABS indicator light does not light up when turn-
ing the ignition switch to ON.
STORED DTCs (Diagnostic Trouble Codes)
The maximum of six DTCs can be recorded. In these records, duplication of the same DTC will not occur. If
the system detects the 7th DTC, it overwrites the record of the oldest DTC.
Check and see if any diagnostic trouble code remains, by actually running the machine to activate ABS and
by carrying out the self-diagnosis after deleting the diagnostic trouble code once the malfunctioned part is
repaired.
