MAINTENANCE OF THE ABS ECU
Checking the ABS ECU
1. Check:Terminals  “1” of the ABS ECU
Cracks/damage   Replace the hydraulic unit 
assembly and the brake pipes that are con-
nected to the assembly as a set.
 Terminals  “2” of the ABS ECU coupler
Defective connections/contamination/discon-
nections   Repair or clean.TIP
If the ABS ECU coupler is clogged with mud or 
dirt, clean with compressed air.

ABS TROUBLESHOOTING OUTLINE
This section describes the troubleshooting for the ABS in detail. Read this service manual carefully and 
make sure you fully understand the information provided before repairing any malfunctions or perform-
ing service.
The ABS ECU (electronic control unit) has a self-diagnosis function. When failures occur in the system, 
the ABS warning light on the meter assembly indicates a malfunction.
The following troubleshooting describes the problem identification and service method according to the 
fault codes indicated by the ABS warning light flash pattern. For troubleshooting items other th\
an the 
following items, follow the normal service method.
WARNING
EWA23P1017
When maintenance or checks have been performed on components related to the ABS, be sure 
to perform a final check before delivering the vehicle to the customer. (Refer to  “[D-3] FINAL 
CHECK ” on page 8-121.)
ABS operation when the ABS warning light comes on
1. ABS is canceled and the braking reverts to normal braking. Futhermore, the braking perf\
ormance of  the unified brake system could be reduced.
A malfunction was detected using the ABS self-diagnosis function.
2. The ABS warning light comes on, and then goes off when starting the engine   ABS and UBS op-
eration is normal.
 The ABS warning light comes on for 2 seconds, and then goes off every time the main switch is 
set to  “ON ”.
 The ABS warning light comes on while the start switch is being pushed.
3. The ABS warning light flashes   ABS and UBS operation is normal.
 Refer to “ BASIC INSTRUCTIONS FOR TROUBLESHOOTING ” on page 8-86.
Self-diagnosis and servicing
The ABS ECU has a self-diagnosis function. By utilizing this function, quick problem identification and 
service are possible. Previous malfunctions can be checked since the ABS ECU also stores the mal-
function history.
The ABS warning light flash pattern indicates all the fault codes recorded in the ABS ECU.
Note all of the indicated fault codes if more than two fault codes are stored in the memory. When the \
service is finished, check the normal operation of the vehicle, and then delete the fault code(s). (Refer 
to  “[D-3] FINAL CHECK ” on page 8-121.) By deleting the fault codes stored in the ABS ECU memory, 
it is possible to pursue the cause correctly if another malfunction occurs.

haha ABS (ANTI-LOCK BRAKE SYSTEM)8-86
TIP
The ABS performs a self-diagnosis test for a few seconds each time the vehicle first starts off after the 
main switch was set to “ ON”. During this test, a “ clicking” noise can be heard from under the rider seat, 
and if the brake lever or brake pedal are even slightly applied, a vibration can be felt at the lever and 
pedal, but these do not indicate a malfunction.
Special precautions for handling and servicing a vehicle equipped with A\
BS
NOTICE
ECA23P1050
Care should be taken not to damage components by subjecting them to shocks or pulling on 
them with too much force since the ABS components are precisely adjusted.
 The ABS ECU and hydraulic unit are a united assembly and cannot be disas\
sembled.
 The malfunction history is stored in the memory of the ABS ECU. Delete t\
he fault codes when the ser-
vice is finished. (This is because the past fault codes will be indicat\
ed again if another malfunction 
occurs.)

BASIC INSTRUCTIONS FOR TROUBLESHOOTING
WARNING
EWA23P1018
 Perform the troubleshooting [A]   [B]   [C]  [D] in order. Be sure to follow the order since 
a wrong diagnosis could result if the steps are followed in a different order or omitted.
 Use sufficiently charged regular batteries only.
[A] Malfunction check using the ABS warning light
[B] Detailed check of the malfunction
The results of the self-diagnosis by the ABS ECU can be indicated using \
the ABS warning light flash 
pattern.
[C] Determining the cause and location of the malfunction
Determine the cause of the malfunction from the condition and place where the malfunction occurred.
[D] Servicing the ABS
Execute the final check after disassembly and assembly. Self-diagnosis using the ABS ECU
The ABS ECU performs a static check of the entire system when the main switch is set to 
“ON”. It 
also checks for malfunctions while the vehicle is ridden. Since all malfunctions are recorded after 
they are detected, it is possible to check the recorded malfunction data using the ABS warning 
light flash pattern when the ABS ECU has entered the self-diagnosis mode.

2. The ABS warning light flashes every 0.5 second for more than 6 seconds. The ABS warning light flashes every 0.5 second if no fault code for a past malfunction is stored in 
the memory of the ABS ECU. If no fault code is indicated, make sure that the customer understands 
the possible conditions that may cause the ABS warning light to come on \
or flash even if the system 
is normal.
TIP
The test coupler adapter must be connected to the ABS test coupler to indicate the fault codes. If the 
adapter is not connected, the ABS warning light will come on or flash, but no fault codes will be indicat-
ed.
