I6 CHECK CIRCUIT CLS42 (VT/BN) FOR A SHORT TO GROUND
Ignition OFF.
Disconnect: Indicator Flasher Relay C2047.
Measure the resistance between the electronic flasher relay C2047-1, circuit CLS42 (VT/BN), harness side and ground.
Is the resistance greater than 10,000 ohms?
I7 CHECK THE TURN SIGNAL LAMP CIRCUITS FOR A SHORT TO GROUND
Ignition OFF.
Disconnect: Multifunction Switch C202a.
Disconnect: LH or RH Front Turn Lamp.
Measure the resistance between the multifunction switch C202a-10 (LH turn signal), circuit CLS39 (VT/WH), harness side
and ground; or between the multifunction switch C202a-7 (RH turn signal), circuit CLS41 (GY/YE), harness side and
ground.
Is the resistance greater than 10,000 ohms?
I8 CHECK THE VOLTAGE TO THE INDICATOR FLASHER RELAY
Ignition OFF.
Disconnect: Indicator Flasher Relay C2047.
Ignition ON.
Measure the voltage between the indicator flasher relay C2047-5, circuit CBP20 (YE/VT), harness side and ground.
Is the voltage greater than 10 volts?
I9 CHECK CIRCUIT CBP20 (YE/VT) FOR AN OPEN
Ignition OFF.
Disconnect: SJB C2280b.
Measure the resistance between the SJB C2280b-19, circuit CBP20 (YE/VT), harness side and the indicator flasher relay
C2047-5, circuit CBP20 (YE/VT), harness side.
Is the resistance less than 5 ohms?
I10 CHECK CIRCUIT GD161 (BK/YE) FOR AN OPEN
Ignition OFF.
Measure the resistance between the indicator flasher C2047-2, circuit GD161 (BK/YE), harness side and ground.
Is the resistance less than 5 ohms?
I11 CHECK CIRCUIT CLS42 (VT/BN) FOR AN OPEN
Disconnect: Multifunction Switch C202b.
Measure the resistance between the multifunction switch C202b-2, circuit CLS42 (VT/BN), harness side and the indicator
flasher relay C2047-1, circuit CLS42 (VT/BN), harness side.
