EPS (ELECTRIC POWER STEERING) SYSTEM (for EPS models)
9-75
EBS30287
EPS CONTROL UNIT’S SELF-DIAGNOSTIC FUNCTION
The EPS control unit is equipped with a self-diagnostic function. If this function detects a malfunction in
the EPS system, it lights the EPS warning light to alert the rider that a malfunction has occurred in the
system. Once a malfunction has been detected, it becomes stored in the EPS control unit memory in
the form of a fault code.
• The EPS warning light comes on when the main switch is turned to “
” (on), and then goes off once
the engine is started. If the warning light remains on or comes on after the engine is started, the EPS
system may be defective.
• The electrical circuit of the warning light can be checked by turning the main switch to “ ” (on). If the
warning light does not come on, the electrical circuit may be defective.
TIP
If the steering usage is too heavy (i.e., excessive steering use when the vehicle is traveling at a slow
speed), the power assist is reduced to protect the EPS motor from overheating.
