Inspection and Verification


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 tested and/or the donor vehicle.

1. Verify the customer complaint. As much information as possible should be gathered from the driver to assist in
diagnosing the cause(s). Confirm which of the following two warning types (A or B) exist for the Tire Pressure
Monitoring System when the ignition status is switched from 'OFF' to 'ON'
(A) Check Tire Pressure Warnings. A low tire pressure warning will continuously illuminate the low tire
pressure warning lamp. This warning may be accompanied by a text message such as CHECK TIRE PRESSURE
(refer to owner literature). The manufacturer approved diagnostic system does NOT need to be used. Diagnostic
Trouble Codes (DTCs) are not generated with this type of warning. To extinguish this warning it is essential that,
with the ignition 'ON', all vehicle tires (including the spare) are to be set to the correct pressure as stated in the
vehicle handbook or as indicated on the placard label in the passenger/driver door aperture. It is not necessary
to drive the vehicle to clear 'check tire pressure' warnings - just changing the tire pressure causes the tire
low pressure sensor to transmit new data.
NOTES:

The tire pressures should be set by:
Using a calibrated tire pressure gauge
With 'cold' tires (vehicle parked in the ambient temperature for at least one hour, not in a garage with an
artificial ambient temperature)

If the tire pressure warning does not clear within two minutes, it is likely that the gauge is not correctly
calibrated or the tires are 'warm'. Carry out the following steps until the warning has cleared:

Increase the tire pressures by 3psi
Wait a further two minutes
When the tires are at ambient temperature and a calibrated gauge is available, reset the tire pressures
to the correct pressure.

Tire pressure adjustments are part of routine owner maintenance. Tire pressure adjustments that are
required due to a lack of owner maintenance are not to be claimed under vehicle warranty.

(B) System Fault Warnings. When a system fault is detected, the low tire pressure warning lamp will flash for
approximately 75 seconds prior to being continuously illuminated. Visually inspect for obvious signs of damage
and system integrity. Check for the presence of tire low pressure sensors on all four wheels (note: a tire low
pressure sensor has a metal valve stem rather than a rubber one).
2. Check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

NOTE: If the tester fails to communicate with the Tire Pressure Monitoring System module, the following actions are
recommended:

Remove the Tire Pressure Monitoring System power supply fuse, inspect and re-install (if intact). Test to see if
communications have been re-established.

Remove the Tire Pressure Monitoring System ignition fuse (if applicable), inspect and re-install (if intact). Test to see if
communications have been re-established.
With ignition status set to 'ON', refer to the electrical circuit diagrams and check Tire Pressure Monitoring System
module for power, ignition and ground supplies .
Carry out CAN network integrity test using the manufacturer approved diagnostic system.

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 tested and/or the donor vehicle.
1. Verify the customer concern.
2. Confirm if the Anti-Lock Brake System (ABS) warning light was illuminated, or still is.

NOTE: An intermittent fault may allow the warning light to go off. This does not necessarily mean the fault is not
present. Some warnings will appear to clear when the ignition is cycled. This is often because the warning has flagged as a
result of one of the vehicle's on-board diagnostic routines having run to detect the fault. If the same routine is not run when
the ignition status is set to ON, the warning will not re-flag until the routine does run.

NOTES:


If an engine is suspect, and the vehicle remains under the Manufacturers warranty refer to the Warranty Policy and
Procedure manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a
new engine.


Due to the possibility of loose carbon, that has become trapped between the valve face and seat, effecting the pressure
readings, when carrying out a compression test and some cylinders are found to have low pressures, install the spark plugs,
road test the vehicle and re-test the suspect cylinders. If the correct pressures are restored, no further action is required. www.JagDocs.com

Component Tests
Engine Oil Leaks


NOTE: Before installing new gaskets or oil seals, make sure that the fault is clearly established.

If the oil leak cannot be identified clearly by a visual inspection, carry out an Ultraviolet test:

Fluorescent Oil Additive Method

1. Clean the engine with a suitable cleaning fluid (brake cleaner).

2. Drain the engine oil and refill with recommended oil, premixed with Diesel Engine Oil Dye or equivalent. Use a minimum
14.8 ml (0.5 ounce) to a maximum 29.6 ml (1 ounce) of fluorescent additive to all engines. If oil is not premixed,
fluorescent additive must first be added to the crankcase.

3. Run engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks using a 12 Volt Master UV
Diagnostic Inspection Kit or equivalent. A clear bright yellow or orange area will identify leak. For extremely small
leaks, several hours may be required for the leak to appear.

4. As necessary, pressurize the main oil gallery system to locate leaks due to incorrectly sealed, loose or cocked plugs. If
the flywheel bolts leak oil, look for sealer on the threads.
5. Repair all leaks as necessary.

Compression Test General Remarks
NOTES:

Removing fuses and disconnecting electrical components may cause the Engine Control Module (ECM) to log Diagnostic
Trouble Codes (DTCs). After the measurements have been carried out, DTCs should be cleared from memory by connecting to
the Manufacturer Approved Diagnostic System.


Only check the compression pressure with the valves set to the prescribed clearance (if this can be adjusted).
The compression pressure should be checked with the engine at normal operating temperature.

Check the Compression Pressure


WARNING: Move gear selector lever to 'P' position. Failure to follow this instruction may result in personal injury.
1. Remove the fuel pump relay.

2. Start the engine - the engine will start, run for a few seconds then stall.

3. Remove the spark plugs.
4. Install the compression tester.

5. Install an auxiliary starter switch in the starting circuit. With the ignition switch OFF, using the auxiliary starter switch,
crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number
of compression strokes required to obtain the highest reading.
6. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes.
7. Install the removed components in reverse order, observing the specified tightening torques.

8. Clear all DTCs from the ECM.
Interpretation of the Results


NOTE: Due to the possibility of loose carbon that has become trapped between the valve face and seat effecting the
pressure readings, when carrying out a compression test and cylinders are found to have low pressures, install the spark plugs,
road test the vehicle and re-test the suspect cylinders. If the correct pressures are restored, no further action is required.

The indicated compression pressures are considered within specification if the lowest reading cylinder is within 75% of the
highest reading.

If the cylinder pressures are found to be low, carry out a leakdown test to determine the location of the fault (if any leakback
can be heard through the engine breather system suspect the piston rings, if any leakback can be heard through the inlet
system suspect the inlet valve or seat, if any leakback can be heard through the exhaust manifold suspect the exhaust valve
or seat. If the measurements for two cylinders next to each other are both too low then it is very likely that the cylinder head
gasket between them is burnt through. This can also be recognized by traces of engine oil in the coolant and/or coolant in the

body near to moving parts


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not

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.
