Pinpoint Test E: The Washer Fluid Level Low Warning Is Inoperative/Always On

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. 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.
  1. E1 DETERMINE THE CONDITION 
    NOTE: Verify that the washer fluid reservoir is full and that the key has been cycled at least once prior to carrying out the pinpoint test.
    • Key in ON position.
    • Does the LOW WASHER FLUID LEVEL warning illuminate? 
    1. YES  : Go to  E5.
    2. NO  : Go to  E2.
  2. E2 CHECK THE LOW WASHER FLUID INDICATOR OPERATION 
    • Key in OFF position.
    • Disconnect: Washer Fluid Level Switch C138
      • Fig 1: Connecting Fused (5A) Jumper Wire Between Washer Fluid Level Switch C138-1, Circuit CMC20 (GY/BK)

    • Connect a fused (5A) jumper wire between the washer fluid level switch C138-1, circuit CMC20 (GY/BK), harness side and ground.
    • Key in ON position.
    • Wait one minute.
    • Observe the low washer fluid indicator.
    • Is the low washer fluid indicator on? 
    1. YES  : REMOVE the jumper wire. Go to  E3.
    2. NO  : REMOVE the jumper wire. Go to  E4.
  3. E3 CHECK CIRCUIT GD123 (BK/GY) FOR AN OPEN 
    • Key in OFF position.
      • Fig 2: Measuring Resistance Between Washer Fluid Level Switch C138-2, Circuit GD123 (BK/GY)
      GF0023350Courtesy of FORD MOTOR CO.
    • Measure the resistance between the washer fluid level switch C138-2, circuit GD123 (BK/GY), harness side and ground.
    • Is the resistance less than 5 ohms? 
    1. YES  : INSTALL a new washer reservoir. REFER to WIPERS AND WASHERS . TEST the system for normal operation.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  4. E4 CHECK CIRCUIT CMC20 (GY/BK) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: Instrument Cluster C220
      • Fig 3: Measuring Resistance Between Instrument Cluster C220-5, CMC20 (GY/BK) & Washer Fluid Level Switch C138-1
      GF0032219Courtesy of FORD MOTOR CO.
    • Measure the resistance between the instrument cluster C220-5, circuit CMC20 (GY/BK), harness side and the washer fluid level switch C138-1, circuit CMC20 (GY/BK), harness side.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  E7.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  5. E5 CHECK THE WASHER FLUID SWITCH 
    • Key in OFF position.
    • Disconnect: Washer Fluid Level Switch C138
    • Key in ON position.
    • Wait one minute.
    • Observe the low washer fluid indicator.
    • Did the low washer fluid indicator turn off? 
    1. YES  : INSTALL a new washer fluid reservoir. REFER to WIPERS AND WASHERS . TEST the system for normal operation.
    2. NO  : Go to  E6.
  6. E6 CHECK CIRCUIT CMC20 (GY/BK) FOR A SHORT TO GROUND 
    • Key in OFF position.
    • Disconnect: Instrument Cluster C220
      • Fig 4: Measuring Resistance Between Instrument Cluster C220-5, Circuit CMC20 (GY/BK) & Ground
      GF0032220Courtesy of FORD MOTOR CO.
    • Measure the resistance between the instrument cluster C220-5, circuit CMC20 (GY/BK), harness side and ground.
    • Is the resistance greater than 10,000 ohms? 
    1. YES  : Go to  E7.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  7. E7 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION 
    • Disconnect the instrument cluster connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the instrument cluster connector and make sure it seats correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. YES  : INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER . 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.
