Circuit Description
Battery voltage is supplied directly to the cooling fan relay coils. The PCM controls the relay by grounding the control
circuit via an internal switch called a driver. The primary function of the driver is to supply the ground for the controlled
component. Each driver has a fault line which the PCM monitors. When the PCM commands a component ON, the
voltage of the control circuit should be low (near 0 volts). When the PCM commands the control circuit to a component
OFF, the voltage potential of the circuit should be high (near the battery voltage). If the fault detection circuit senses a
voltage other than what the PCM expected, the fault line status changes causing the DTC to set.
The relay controls the high current flow to the cooling fans. This allows the PCM driver to only have to control the
relatively low current used by the relay.
Conditions for Running the DTC
• The engine speed is greater than 600 RPM.
• The ignition voltage is between 6.0 and 16.0 volts.
Conditions for Setting the DTC
• The PCM detects that the commanded state of the driver and the actual state of the control circuit do not match.
• The conditions must be present for a minimum of 10 seconds.
Action Taken When the DTC Sets
• The PCM activates the Check Powertrain MIL when the diagnostic runs and fails.
• The PCM records the operating conditions at the time the diagnostic fails. The PCM stores this inform ation in the
Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC
• The PCM deactivates the Check Powertrain MIL after the first ignition cycle that the di agnostic runs and does not
fail.
• A last test failed (current DTC) clears when the diagnostic runs and does not fail.
• Use Tech 2 to clear the MIL/DTC.
Diagnostic Aid s
Using the Freeze Frame/Failure Records data may aid in locating an intermittent condition. If you cannot duplicate the
DTC, the information include d in the Freeze Fram e/Fa ilure Record s data can aid in determi ning the dis t an ce trav elle d
since the DTC reported a pass and/or fail. Operate the vehicle within the same freeze frame conditions (RPM, load,
vehicle speed, temperature, etc.) that you observed. This will isolate when the DTC failed.
NOTE
For an intermittent, refer to Section 6C3-2B
Symptoms, in the MY 2003 VY and V2 Series
Service Information.
Test Description
NOTE
The number(s) below refer to the step number(s)
on the diagnostic table.
2/3. Listen for an audible click when the relay operates. Command both ON and OFF states. Repeat the commands if
necessary.
4. This check can detect a partially shorted coil which would cause excessive current flow. Leaving the circuit
energised for 2 minutes allows the coil to warm up. When warm, the coil may open (Amps drop to 0), or short (goes
above 0.75 Amps).
17. If you do not fi nd any trouble in the control circuit or the connection at the PCM, the PCM may be faulty.

GEN III V8 PCM – Engine Cooling Fan Control
Figure 6C3-2C-3 – Cooling Fan Circuits
Powertrain Management – Gen III V8 Engine Page 6C3–10
Page 6C3–10
Circuit Description
The GEN III V8 engine has two, two speed electric engine cooling fan motors which provide the primary means of
moving air through the radiator. The cooling fans are used to cool engine coolant flowing through the radiator and the
refrigerant flowing through the A/C condenser (where fitted).
The engine cooling fan stage 2 relays (R5 & R6) are controlled by the PCM. The PCM controls the ground path for the
engine cooling fan stage 2 relays.
The stage 1 operation of the engine cooling fans is controlled by the PCM through serial data communication to the
BCM. The BCM controls the ground path for the engine cooling fan stage 1 relay (R7).
All three relays in the cooling fan control circuit are us ed to control the ground paths to the electric motors that drive both
fans.
Stage 1 Engine Cooling Fan Operation
The engine cooling fan stage 1 relay is energised by the BCM. The PCM determines when to enable the engine cooling
fan stage 1 operation based on inputs from the A/C request signal, vehicle speed and engine coolant temperature. The
engine cooling stage 1 relay will be turned ON when:
A/C request indicated (YES) and;
Vehicle speed less than 30 km/h
OR
Coolant temperature is greater than a specified value and will remain on until coolant temperature reduces to a
predetermined value.
Stage 2 Engine Cooling Fan Operation
The engine cooling fan stage 2 operation is controlled by the PCM based on input from the Engine Coolant Temperature
Sensor (ECT) and the A/C Pressure Sensor. The PCM will only turn ON the stage 2 engine cooling fan relays if the stage
1 engine cooling fan relay has been switched ON and the following conditions are satisfied.
• There is a BCM message response fault, which will cause a DTC to set.
• An engine coolant temperature sensor failure is detected, such as DTC P0117, P0118, P1114, P1115.
• Coolant temperature greater than a specified value.
• A/C pressure greater than a specified value.
If the stage 1 cooling fan relay was OFF when the criteria was met to turn the stage 2 cooling fan ON, the cooling fan
stage 2 relays will operate 5 seconds after the stage 1 cooling fan. The A/C Refrigerant Pressure Sensor can also enable
the engine cooling fan stage 2 relays. The A/C Refrigerant Pressure Sensor will provide a signal to the PCM when A/C
pressure becomes too high; approximately 2,600 kPa.
For replacement of the cooling fan motor, refer to Section 6B3, 2.15 Cooling Fans and Shroud Assembly in the MY 2003
VY and V2 Series Service Information.
Test Description
NOTE
The number(s) below refer to the step number(s)
on the diagnostic table.
2. This entire diagnostic procedure must begin with a cold engine - at ambient air temperature. If the coolant is hot
when diagnosis is performed, replacement of good parts will result. The fans should not be running if engine
coolant temperature is less than 99° C and air conditioning is not ON.
3. Listen for an audible click when the relay operates. Command both ON and OFF states. Repeat the commands if
necessary.
