Pinpoint Test I: The Turn Signal Lamps Are Inoperative

WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
  1. I1 CHECK THE TURN SIGNALS 
    • Key in ON position.
    • Place the multifunction switch in the LH or RH turn position.
    • Are the turn signal lamps illuminated but not flashing? 
    1. Yes  : GO to  I9.
    2. No  : GO to I2.
  2. I2 CHECK THE STOPLAMPS 
    • Observe the rear lamps while pressing and releasing the brake pedal.
    • Do the stoplamps operate correctly? 
    1. Yes  : GO to I3.
    2. No  : REFER to STOPLAMPS .
  3. I3 CHECK CIRCUIT 44 (LB) FOR A SHORT TO GROUND 
    • Listen to the indicator flasher while placing the multifunction switch in the LH and RH turn positions.
    • Is there a rapid clicking sound coming continuously from the indicator flasher? 
    1. Yes  : REPAIR the circuit. TEST the system for normal operation.
    2. No  : GO to I4.
  4. I4 CHECK THE VOLTAGE TO THE INDICATOR FLASHER 
    • Key in OFF position.
    • Disconnect: Indicator Flasher C2047.
    • Key in ON position.
    • Measure the voltage between the indicator flasher C2047 pin 30, circuit 8 (OG/YE), harness side and ground.

    • Is the voltage greater than 10 volts? 
    1. Yes  : GO to  I6.
    2. No  : GO to I5.
  5. I5 CHECK CIRCUIT 8 (OG/YE) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: SJB C2280b.
    • Measure the resistance between the indicator flasher C2047 pin 30, circuit 8 (OG/YE), harness side and the SJB C2280b pin 19, circuit 8 (OG/YE), harness side.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to  I8.
    2. No  : REPAIR the circuit. TEST the system for normal operation.
  6. I6 CHECK CIRCUIT 44 (LB) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: Multifunction Switch C202a.
    • Measure the resistance between the multifunction switch C202b pin 2, circuit 44 (LB), harness side and the indicator flasher C2047 pin 87, circuit 44 (LB), harness side.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to I7.
    2. No  : REPAIR the circuit. TEST the system for normal operation.
  7. I7 CHECK THE MULTIFUNCTION SWITCH 
    • Carry out the multifunction switch component test.

      Refer to the appropriate SYSTEM WIRING DIAGRAMS for schematic and connector information.

    • Is the multifunction switch OK? 
    1. Yes  : GO to  I11.
    2. No  : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES . TEST the system for normal operation.
  8. I8 CHECK FOR CORRECT SMART JUNCTION BOX (SJB) OPERATION 
    • Key in OFF position.
    • Disconnect all SJB connectors.
    • Check for:
      • Corrosion
      • Pushed-out pins
    • Connect all SJB connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. Yes  : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC CONTROL MODULES . TEST the system for normal operation.
    2. No  : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
  9. I9 CHECK THE MULTIFUNCTION SWITCH FOR A SHORT TO POWER 
    • Carry out the multifunction switch component test.

      Refer to the appropriate SYSTEM WIRING DIAGRAMS for schematic and connector information.

    • Is the multifunction switch OK? 
    1. Yes  : GO to I10.
    2. No  : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES . TEST the system for normal operation.
  10. I10 CHECK CIRCUIT 44 (LB) FOR A SHORT TO POWER 
    • Disconnect: Indicator Flasher C2047.
    • Measure the voltage between the indicator flasher C2047 pin 87, circuit 44 (LB), harness side and ground.
