Diagnosis and Testing

Principle of Operation

For a detailed description of the engine cooling system and operation, refer to the relevant description and operation section of
the workshop manual. Engine Cooling, Section - 303-03

Inspection and Verification


WARNING: Moving parts can cause severe injury, keep clear of moving parts, never place your hands or any part of your
body near to moving parts


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle
NOTES:


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

1. Verify the customer concern

2. Visually inspect for obvious signs of mechanical or electrical damage

Visual Inspection
Mechanical Electrical
Coolant leaks
Coolant hoses
Coolant expansion tank
Radiator
Heater core
Accessory drive belt
Cooling fan
Fuses
Harnesses
Loose or corroded connector(s)
Engine coolant temperature sensor
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step

4. If the cause is not visually evident, verify the symptom and refer to the symptom chart, alternatively check for
diagnostic trouble codes (DTCs) and refer to the DTC Index
Symptom Chart

Symptom Possible Causes Action Coolant loss
Hoses
Hose connections
Radiator
Water pump
Heater core
Gaskets
Engine casting cracks
Engine block core
plugs Carry out a visual inspection. If there are no obvious leaks, carry out a
cooling system pressure test. Rectify any leaks as necessary Overheating
Low/contaminated
coolant
Thermostat
Cooling fan Check the coolant level and condition. Carry out a cooling system pressure
test. Rectify any leaks as necessary. Check the thermostat and rectify as
necessary. Check the cooling fan operation, make sure the cooling fan
rotates freely. Check for obstructions to the air flow over the radiator.
Rectify as necessary

Symptom Possible Causes Action Engine coolant

PINPOINT TEST A : TEST
CONDITIONS DETAILS/RESULTS/ACTIONS A1: CHECK FOR COOLING FAN RELATED DTCS

NOTE: For a complete list of all diagnostic trouble codes that could be logged on this vehicle, please refer
to section 100-00. Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the
5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits
give extra information read by the manufacturer-approved diagnostic system). 1 Using the manufacturer approved diagnostic system check the engine control module for DTCs 2 P0480-00 & P0480 with any other different last 2 digits in the DTC 3 P0481-00 & P0481 with any other different last 2 digits in the DTC 4 P0483-00 & P0483 with any other different last 2 digits in the DTC Are any of the cooling fan related DTCs listed, logged in the engine control module?
Yes
Please refer to section 100-00 and refer to the relevant DTC index and carry out repair procedure
Using the manufacturer approved diagnostic system clear all stored diagnostic trouble codes from the
diagnosis menu tab
Proceed to the test step A9 'Cooling fan validation procedure'
No
Proceed to the next step. A2 'Check for other DTCs' A2: CHECK FOR OTHER DTCS 1 Using the manufacturer approved diagnostic system check the engine control module for DTCs Are any other DTCs listed, logged in the engine control module?
Yes
Please refer to section 100-00 and refer to the relevant DTC index and carry out repair procedure
Using the manufacturer approved diagnostic system clear all stored diagnostic trouble codes from the

and Vacuum Filling
General Procedures

Draining

1. Refer to: Radiator Splash Shield (501-02 Front End Body Panels, Removal and Installation).


2. WARNING: Release the cooling system pressure by slowly
turning the coolant expansion tank cap a quarter of a turn.
Cover the expansion tank cap with a thick cloth to prevent
the possibility of scalding. Failure to follow this instruction
may result in personal injury.
CAUTIONS:


Since injury such as scalding could be caused by
escaping steam or coolant, make sure the vehicle cooling
system is cool prior to carrying out this procedure


Be prepared to collect escaping coolant.



3. WARNING: Do not work on or under a vehicle supported only by a jack.
Always support the vehicle on safety stands.
Raise and support the vehicle.


4. CAUTION: Be prepared to collect escaping coolant.

5. Torque: 2 Nm 6. CAUTION: Be prepared to collect escaping coolant.

NOTE: Only carry out the following step if the coolant
is to be drained from the engine.












7. NOTE: This step is only required if previously
removed.

Torque: 50 Nm












Filling

1. Refer to: Radiator Splash Shield (501-02 Front End Body Panels, Removal and Installation).

2. Lower the vehicle.
