meter assembly sub-wire harness coupler
(meter assembly side) as shown.
Positive tester probe
→ red/white 1
Negative tester probe
→ ground
• Set the main switch to “ON”.
• Measure the voltage (DC 12 V) of red/
white 1 and ground at the meter assem-
bly sub-wire harness coupler.
• Is the voltage within specification?
