(1) Checking
(A) Combination Switch
Combination Switch
1. Remove the switch board, and disconnect the combination
switch connector after turning the main switch off.
2. Perform the following checkings.
W1041514
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.
W1041711
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.
W1042584
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.
