Diagnostic Test

  1. 1) INSPECT THE LOW COOLANT INDICATOR LAMP 

    Turn the ignition off.

    Remove the Low Coolant Indicator Lamp from the Instrument Cluster and inspect the lamp for an open filament.

    Is the lamp filament open? 

    Yes 

    1. Replace the Low Coolant Indicator Lamp. Refer to INSTRUMENT CLUSTER BULB REPLACEMENT PROCEDURE .
    2. Perform *BODY VERIFICATION TEST .

    No 

    1. Go to  2).
  2. 2) INSPECT THE LOW WASHER FLUID INDICATOR LAMP 

    With the ignition off.

    Remove the Low Washer Fluid Indicator Lamp from the Instrument Cluster and inspect the lamp for an open filament.

    Is the lamp filament open? 

    Yes 

    1. Replace the Low Washer Fluid Indicator Lamp. Refer to INSTRUMENT CLUSTER BULB REPLACEMENT PROCEDURE .
    2. Perform *BODY VERIFICATION TEST .

    No 

    1. Go to  3).
  3. 3) MEASURE COOLANT LEVEL SENSOR RESISTANCE

    With the ignition off.

    Disconnect the Washer Fluid Level Switch harness connector.

    NOTE: Check connectors - Clean/repair as necessary.

    Measure the resistance between cavity 1 and cavity 2 of the Washer Fluid Level Switch connector.

    Is the resistance between 145 and 185 ohms? 

    Yes 

    1. Go to  5).

    No 

    1. Replace the Washer Fluid Level Switch. Refer to REMOVAL .
    2. Perform *BODY VERIFICATION TEST .
  5. 5) MEASURE COOLANT LEVEL SENSOR/WASHER FLUID LEVEL SWITCH CIRCUIT RESISTANCE

    With the ignition off.

    Disconnect the Instrument Cluster C1 harness connector.

    NOTE: Check connectors - Clean/repair as necessary.

    Connect a jumper wire between cavity 1 and cavity 2 of the Coolant Level Sensor harness connector.

    Connect a jumper wire between cavity 1 and cavity 2 of the Washer Fluid Level Switch harness connector.

    Measure the resistance between cavity 4B and 12B of the Instrument Cluster C1 harness connector.

    Is the resistance below 5.0 ohms? 

    Yes 

    1. Replace the Instrument Cluster. Refer to REMOVAL .
    2. Perform *BODY VERIFICATION TEST .

    No 

    1. Repair the Coolant Level Sensor/Washer Fluid Level Switch circuit for an open.
    2. Perform *BODY VERIFICATION TEST .
