(1) Combination Switch
Combination Switch
1. Remove the steering wheel and panel lower cover.
2. Disconnect the combination switch connector.
3. Remove the combination switch (1) and perform the following
checks 1) to 8).

1) Connector Voltage
1. Measure the voltage with a voltmeter across the connector B1
terminal and chassis when the main switch is "ON" position.
2. If the voltage differs from the battery voltage, the wiring harness
and main switch is faulty.

2) Head Light Switch Continuity when Setting Switch at OFF
Position
1. Set the light switch to the OFF position.
2. Measure the resistance with an ohmmeter across the B1
terminal to the T terminal, the B1 terminal to the terminal 1.
3. If infinity is not indicated, the head light switch is faulty.

3) Head Light Switch Continuity when Setting Switch at ON
Position
1. Set the light switch to the ON position.
2. Measure the resistance with an ohmmeter across the B1
terminal to the T terminal and the B1 terminal to the terminal 1.
3. If 0 Ω is not indicated, the head light switch is faulty.

4) Turn Signal Light Switch Continuity When Setting Switch
Knob OFF Position
1. Set the turn signal light switch to the OFF position.
2. Measure the resistance with an ohmmeter across the B2
terminal and L terminal, the B2 terminal and R terminal.
3. If infinity is not indicated, the combination switch is faulty.
