(20) Combination Switch

Remove the Combination Switch
1. Remove the instrument panel, and disconnect the combination
switch 8P connector (1) after turning the main switch OFF
position.
2. Perform the following checkings.
(1) 8P Connector
1) Connector Voltage
1. Disconnect the 8P connector from the combination switch.
2. Measure the voltage with a voltmeter across the connector B1
terminal to chassis and the B2 terminal to chassis when the
main switch is "OFF" position.
3. If the voltage differs from the battery voltage, the wiring harness
is faulty.

"OFF" position
2) Light Switch Continuity when Setting Switch at OFF Position
1. Disconnect the combination switch connector.
2. Set the light switch to the OFF position.
3. Measure the resistance with an ohmmeter across the B1
terminal to the T terminal, the B1 terminal to the 1 terminal and
the B1 terminal to the 2 terminal.
4. If infinity is not indicated, the head light switch is faulty.
B1 terminal – T terminal
Resistance (Switch
B1 terminal – 1 terminal
at OFF position)
B1 terminal – 2 terminal
3) Light Switch Continuity when Setting Switch at HIGH-BEAM
1. Measure the resistance with an ohmmeter across the B1
terminal to the T terminal and the B1 terminal to the 1 terminal.
2. If 0 ohm is not indicated, the head light switch is faulty.
Resistance (Switch B1 terminal – T terminal
at HIGH-BEAM
B1 terminal – 1 terminal
position)
4) Light Switch Continuity when Setting Switch at LOW-BEAM
Position
1. Measure the resistance with an ohmmeter across the B1
terminal to the T terminal and the B1 terminal to the 2 terminal.
2. If 0 ohm is not indicated, the head light switch is faulty.
Resistance (Switch B1 terminal – T terminal
at LOW-BEAM
B1 terminal – 2 terminal
position)
