operation.
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?
Yes
INSTALL a new indicator flasher relay. TEST the
system for normal operation.
No
REPAIR the circuit. TEST the system for normal
operation.
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?
Yes
INSTALL a new multifunction switch. REFER to
Section 211-05. TEST the system for normal
operation.
No
REPAIR the circuit in question. TEST the system
for normal operation.
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?
Yes
GO to I10.
No
VERIFY the SJB fuse 20 (10A) is OK. If OK, GO
to I9 .
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?
Yes
GO to I13.
No
REPAIR the circuit. TEST the system for normal
operation.
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?
Yes
GO to I11.
No
REPAIR the circuit. TEST the system for normal
operation.
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.
Yes
GO to I12.
