Failure to follow this instruction may result in personal injury.
CAUTION: Diesel fuel injection equipment is manufactured to very precise tolerances
and fine clearances. It is therefore essential that absolute cleanliness is observed when
working with these components. Always fit blanking plugs to any open orifices or lines.
NOTE: As well as carrying out its normal function the glow plug indicator also acts as an
engine check lamp which will flash continuously when a hard diagnostic trouble code
(DTC) is detected by the powertrain control module (PCM). Soft DTCs are also stored by
the PCM but will only be known if the system is checked for DTCs using WDS.
NOTE: If a DTC is detected, all DTCs must be cleared after the concern is repaired. Failure
to clear all DTCs may cause driveability concerns.
NOTE: If the fuel level in the fuel tank drops below approximately four litres, rough
running will occur. This is to signal to the driver that the vehicle requires refuelling in
order to prevent the fuel system from running dry.
1. 1. Verify the customer concern.
2. 2. Visually inspect for obvious signs of mechanical or electrical damage.

3. 3. If an obvious cause for an observed or reported concern is found, correct the cause
(if possible) before proceeding to the next step.
NOTE: A PCM calibration update should only be carried out if it is applicable to the
4.
symptoms exhibited by the vehicle.
4. If the cause is not visually evident, verify the symptom and refer to WDS. Check
for the availability of an applicable PCM calibration update. Continue with WDS and
retrieve the DTCs.
5. 5. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart
below to continue diagnostics.
