Diagnostic Aids

* Test the ECT and the IAT sensor at various temperature levels in order to evaluate the possibility of a skewed sensor. A skewed sensor can

result in a DTC or a driveability condition. Refer to Temperature Versus Resistance - Engine Coolant Temperature Sensor (See: Powertrain

Management/Computers and Control Systems/Specifications/Temperature Versus Resistance - Engine Coolant Temperature Sensor) and

Action Taken When the DTC Sets

The ECM records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the ECM stores this information in the

Failure Records. If the diagnostic reports a failure on the second ignition cycle the ECM records the operating conditions at the time of the failure.

The ECM writes the operating conditions to the Freeze Frame and updates the Failure Records. The ECM illuminates the malfunction indicator

lamp (MIL) when one of the following occur:

* The ECM detects the same fuel trim failure during 2 consecutive trips.

* The ECM detects any fuel trim failure during any subsequent trip if the conditions at the time of failure meet the following criteria:

- The engine load is within 20 % of the previous test that failed.

- The engine speed is within 375 RPM of the previous test that failed.

- The engine coolant temperature is in the same range of the previous test that failed.

Conditions for Clearing the MIL/DTC

* The ECM turns OFF the malfunction indicator lamp (MIL) at the beginning of the fourth ignition cycle, after 3 ignition cycles that the

diagnostic runs and does not fail.

* A current DTC, Last Test Failed, clears when the diagnostic runs and passes.

* A history DTC and related Freeze Frame data clears after 40 warm-up cycles, if no failures are reported by this or any other emission related

diagnostic.

* Clear the MIL and the DTC with a scan tool.

trim faults are repaired. A fuel trim fault may cause default actions such as harsh shifts and illumination of the ABS/TCS indicators.

* E85 compatible engine only-Over estimation of the ethanol content will result in a rich shift of fuel trim values, and under-estimation will

result in a lean shift of fuel trim values. A fuel trim DTC may set if the learned alcohol content, Fuel Alcohol Content parameter on the scan

Warning

Under pressure, the temperature of the solution in the radiator can be considerably higher, without boiling. Removing the radiator cap while the

engine is hot (pressure is high), will cause the solution to boil instantaneously, with explosive force. The solution will spew out over the engine,

fenders, and the person removing the cap. Serious bodily injury may result. Flammable antifreeze, such as alcohol, is not recommended for use at

any time. Flammable antifreeze could cause a serious fire.

1. Turn OFF the ignition.

2. Inspect the cooling system surge tank for the proper engine coolant level. Refer to Cooling System Leak Testing (See: Engine, Cooling and

Exhaust/Cooling System/Testing and Inspection/Component Tests and General Diagnostics) and Cooling System Draining and Filling (Static

Diagnostic Aids

* This diagnostic uses a comprehensive approach to the diagnosis of the KR31 auxiliary coolant pump relay and its related circuits. The

auxiliary coolant pump relay is a printed circuit board (PCB) relay. The relay is an integral component to the underhood bussed electrical

center (UBEC). It cannot be removed and it is not visible.

* Much of the diagnosis is performed at the ECM connectors. Great care should be taken to ensure that the correct terminals are tested and the

proper test probes are utilized when performing this diagnostic.

* The test lamp is used to provide a visual aid to observe the integrity of the KR31 relay, the UBEC and the relay control circuit.

* Grounding terminal X2-58 activates the powertrain relay, which will supply power through KR31 relay coil and the relay control circuit.

Under normal circumstances the test lamp will illuminate with dim intensity due to the load created by the KR31 relay coil. If the test lamp

does not illuminate, or illuminates brightly a condition exists in the KR31 relay control circuit or the UBEC.

Conditions for Setting the DTC

* The average long term FT weighted average value is more or less than a calibrated value.

* The above condition is present for approximately 3 min after the Conditions for Running the DTC have been met.

Action Taken When the DTC Sets

The ECM records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the ECM stores this information in the

Failure Records. If the diagnostic reports a failure on the second ignition cycle the ECM records the operating conditions at the time of the failure.

The ECM writes the operating conditions to the Freeze Frame and updates the Failure Records. The ECM illuminates the malfunction indicator

lamp (MIL) when one of the following occur:

* The ECM detects the same fuel trim failure during 2 consecutive trips.

* The ECM detects any fuel trim failure during any subsequent trip if the conditions at the time of failure meet the following criteria:

- The engine load is within 20 % of the previous test that failed.

- The engine speed is within 375 RPM of the previous test that failed.

- The engine coolant temperature is in the same range of the previous test that failed.

Conditions for Clearing the MIL/DTC

* The ECM turns OFF the malfunction indicator lamp (MIL) at the beginning of the fourth ignition cycle, after 3 ignition cycles that the

diagnostic runs and does not fail.

* A current DTC, Last Test Failed, clears when the diagnostic runs and passes.

* A history DTC and related Freeze Frame data clears after 40 warm-up cycles, if no failures are reported by this or any other emission related

diagnostic.

* Clear the MIL and the DTC with a scan tool.

Circuit/System Verification

* Disregard any transmission symptoms, antilock brake system (ABS) indicators, and traction control system (TCS) indicators until any fuel

trim faults are repaired. A fuel trim fault may cause default actions such as harsh shifts and illumination of the ABS/TCS indicators.

* E85 compatible engine only-Over estimation of the ethanol content will result in a rich shift of fuel trim values, and under-estimation will

result in a lean shift of fuel trim values. A fuel trim DTC may set if the learned alcohol content, Fuel Alcohol Content parameter on the scan

tool, is different than the measured alcohol content in the vehicle such that fuel trim values exceed failure threshold values. Refer to Fuel

Composition Diagnosis (See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Component Tests and

General Diagnostics).

* Verify that other DTCs are not set.

Warning

Under pressure, the temperature of the solution in the radiator can be considerably higher, without boiling. Removing the radiator cap while the

engine is hot (pressure is high), will cause the solution to boil instantaneously, with explosive force. The solution will spew out over the engine,

fenders, and the person removing the cap. Serious bodily injury may result. Flammable antifreeze, such as alcohol, is not recommended for use at

any time. Flammable antifreeze could cause a serious fire.

1. Turn OFF the ignition.

2. Inspect the cooling system surge tank for the proper engine coolant level. Refer to Cooling System Leak Testing (See: Engine, Cooling and

Exhaust/Cooling System/Testing and Inspection/Component Tests and General Diagnostics) and Cooling System Draining and Filling (Static
