ABS

9.1.7 TROUBLESHOOTING

- When the key is turned to ON, the panel light comes on during the initial test routine and then √ if the ABS is on √ goes
out.
- When the controller ground pins are not connected, the light stays on steady (fault not detected by control unit), meaning
that the ABS is off.
- With the Axone tester connected, the ABS will be off and the light comes on because the controller goes into diagnostic
mode.
- An interrupted or missing brake light or an interrupted diode are indicated by a front or rear brake lever fault.
- If the 10-A fuse is interrupted, the ABS light on the panel comes on and communication with Axone cannot be estab-
lished.
- If the 30-A fuse is interrupted, the ABS light on the panel comes on and communication with Axone is established any-
way.
