Front Wheel Turning Angle Sensor
1. Separate the arm (4) from angle sensor lever (5).
2. Disconnect the connector (1).
3. Remove the sensor with sensor cover (3), then remove the
sensor from sensor cover (3).
4. Measure the angle sensor resistance between the A terminal
(6) and ground C terminal (8).
5. Set the test lead of tester between B terminal (7) and ground
C terminal (8).
Turn the sensor lever (5) slowly and check the changing of
resistance value.
6. If measurement is not within the factory specifications, replace
it.
A If replaced a front wheel turning angle sensor, be sure to
operate the "Fine adjustment system".
Bi-speed Controller
A The controller used micro-computer, it is necessary a
special checking instrument to inspect it.
A If the connector voltage is in good condition and the
output voltage is not in good, the controller may faulty.
1) Connector Voltage
1. Disconnect the connector (1).
2. Turn the main switch to ON position. It is not necessary to run
the engine.
3. Measure the voltage with voltmeter across the 7 terminal (4)
and 11 terminal (3). If the voltage differs from the battery
voltage, check the fuse, wiring harness or ground condition.
