Beacon Switch
1. Disconnect the 6P connector (2) from beacon switch (1) after
disconnect the battery negative code.
2. Remove the beacon switch (1).
3. Perform the following checking.
(1) Beacon Switch
1) Connector Voltage
1. Connect the battery negative code, and turn on the light switch,
then measure the voltage with a voltmeter across the d terminal
and chassis.
2. If the voltage differ from the battery voltage, the wiring harness
is faulty.
Voltage d terminal – Chassis

2) Beacon Switch Continuity
1. Measure the resistance with ohmmeter across the a terminal
and c terminal, and across the d terminal and e terminal.
2. If the measurement is not following below, the beacon switch or
the bulb are faulty.
