Pinpoint Test N: The Hazard Lamps Are Inoperative/Always On

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: The battery ground cable must be disconnected for accurate test results when checking ground circuits for continuity to ground.
  1. N1 CHECK FOR CORRECT HIGH BEAM OPERATION 
    • Key in OFF position.
    • Place the headlamp switch in the HEADLAMPS ON position.
    • Place the multifunction switch in the HIGH BEAM position while observing the high beam headlamps.
    • Do the high beams illuminate? 
    1. YES  : Go to  N2.
    2. NO  : REFER to Headlamps  in this article to continue diagnosis of the high beam headlamps.
  2. N2 CHECK CIRCUIT CLS32 (BN/YE) FOR A SHORT TO GROUND 
    • PLACE the headlamp switch in the OFF position.
    • Disconnect: Multifunction Switch C202
    • Disconnect: SJB C2280b
    • Measure the resistance between the multifunction switch C202-1, circuit CLS32 (BN/YE), harness side and ground.

    • Is the resistance greater than 10,000 ohms? 
    1. YES  : Go to  N3.
    2. NO  : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
  3. N3 CHECK CIRCUIT CLS32 (BN/YE) FOR AN OPEN 
    • Measure the resistance between the SJB C2280b-48, circuit CLS32 (BN/YE), harness side and the multifunction switch C202-1, circuit CLS32 (BN/YE), harness side.
      • Fig 2: Measuring Resistance

    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  N4.
    2. NO  : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test..
  4. N4 CHECK THE MULTIFUNCTION SWITCH 
    • Connect: Multifunction Switch C202
    • While pressing and releasing the hazard lamp switch, measure the resistance between the SJB C2280b-48, circuit CLS32 (BN/YE), harness side and ground.
      • Fig 3: Checking Hazard Flasher Lamp Switch
      GF0023461Courtesy of FORD MOTOR CO.
    • Is the resistance less than 5 ohms with the switch pressed and greater than 10,000 ohms with the switch released? 
    1. YES  : Go to  N5.
    2. NO  : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES article. CLEAR the DTCs. REPEAT the self-test.
  5. N5 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all the SJB connectors.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect all the 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 MODULES article. TEST the system for normal operation.
    2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
