Pinpoint Test J: The Turn Signal Lamps Are Never On

J1 CHECK THE VOLTAGE TO THE ELECTRONIC FLASHER
- Disconnect: Electronic Flasher C2141.
- Key in ON position.
- Measure the voltage between the following electronic flasher C2141 circuits, harness side and ground.
  - Pin 2, Circuit 1039 (BK/YE).
  - Pin 3, Circuit 383 (RD/WH).

- Are the voltages greater than 10 volts?
1. Yes: GO to J2.
2. No: REPAIR the circuit in question. TEST the system for normal operation.
J2 CHECK CIRCUIT 44 (LB)
- Key in OFF position.
- Disconnect: Multifunction Switch C202b.
- Measure the resistance between multifunction switch C202b Pin 44, Circuit 44 (LB), harness side and the electronic flasher C2141 Pin 1, Circuit 44 (LB), harness side; and between multifunction switch C202b Pin 44, Circuit 44 (LB), harness side and ground.

- Is the resistance less than 5 ohms between the multifunction switch and the electronic flasher, and greater than 10,000 ohms between the multifunction switch and ground?
1. Yes: GO to J3.
2. No: REPAIR the circuit. TEST the system for normal operation.
J3 CHECK THE CONTINUITY OF THE MULTIFUNCTION SWITCH
- Carry out the multifunction switch component test.
  Refer to COMPONENT TESTING for schematic and connector information.
- Is the switch OK?
1. Yes: INSTALL a new electronic flasher. TEST the system for normal operation.
2. No : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES . TEST the system for normal operation.
