ANTI-LOCK BRAKE SYSTEM (ABS; SH300A/AII/AIII)
PROBLEM CODE INDICATION PATTERN
• The ABS indicator indicates the problem code by blinking a specified number of times.
The ABS indicator denotes the problem codes from 11 to 81. The indicator has two types of blinks, a
long blink and short blink. The long blink lasts for 1.3 seconds, the short blink lasts for 0.3 seconds.
When two long blinks occur, and three short blinks, that problem code is 23 (two long blinks = 20
blinks, three short blinks = 3 blinks). Then, go to the troubleshooting and see problem code 23.
• When the ABS control unit stores some problem codes, the ABS indicator shows the problem codes
in the order from the lowest number to highest number. For example, when the indicator indicates
code 12, then indicates code 23, two failures have occurred.
• ABS control unit (ECU) can record only the first problem data detected while the ignition switch is
turned "ON" until it is turned "OFF" even when there are multiple failures.
• If the problem code is not stored, the ABS indicator stays on.
When the problem code is not stored:
RETRIEVAL OF PROBLEM CODE
• The problem code is not erased by turning the ignition switch to "OFF" while the problem code is
being output. Note that turning the ignition switch to "ON" again does not indicate the problem code.
To show the problem code retrieval procedures from the beginning.
• After diagnostic troubleshooting, erase the problem code then test ride the scooter above 30 km/h
(18 mph) and check the other problem code by retrieving the self-diagnosis system.
• Do not apply the front or rear brake during retrieval.
1. Turn the ignition switch "OFF".
