1. Remove the instrument panel and disconnect the 6P connector
(2) from hazard switch (1) after disconnect the battery negative
code.
2. Remove the hazard switch (1).
3. Perform the following checking.
(1) Hazard 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
(1) 6P Connector
2) Hazard 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 hazard switch or
the bulb are faulty.
