Inspection and Verification
WARNINGS:
Do not smoke or carry lighted tobacco of any type when working on or near any fuel
related components. Highly flammable mixtures are always present and may ignite.
Failure to follow these instructions may result in personal injury.
This procedure involves fuel handling. Be prepared for fuel spillage at all times.
Failure to follow this instruction may result in personal injury.
CAUTION: Diesel fuel injection equipment is manufactured to very precise tolerances
and fine clearances. The fuel injection pump is fully electronic and has no linkages or
cables. Do not grease any of the fuel injection pump terminals or connectors. 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 lamp 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 cause is repaired. Failure
to clear all DTCs may cause driveability concerns.
NOTE: If the fuel level in the fuel tank drops below approximately 4 liters, 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.

(if possible) before proceeding to the next step.
4. 4. If the cause is not visually evident, verify the symptom and refer to Symptom
