Q: Do all the voltages measure 4.7 volts or less?
YES (vehicles with KOS) : Go to Step 15.
YES (vehicles with WCM) : Go to Step 16.
NO (vehicles with KOS and WCM) : Go to Step 48.
STEP 15. Check the wiring harness between joint
connector (CAN1) C-105 and KOS-ECU connector C-05 for
a short to power supply. Measure the voltage at joint
connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the
voltage at the wiring harness side of joint connector
(CAN1).
(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN1)
terminal 9 and body ground.
OK: 4.7 volts or less
