DIAGNOSIS AND TESTING

Overview

The turbocharger system for this vehicle differs from previous models in that it uses twin turbochargers rather than a single unit serving both banks.

For information on the operation of the system: REFER to: Turbocharger (303-04F Fuel Charging and Controls - Turbocharger - TDV8 3.6L Diesel, Description and Operation).

Inspection and Verification

WARNINGS:

The following tests may involve working in close proximity to hot components. Make sure adequate protection is used. Failure to follow this instruction may result in personal injury.
The turbocharger can continue to rotate after the engine has stopped. Do not attempt to check the turbocharger until one minute has elapsed since the engine was switched off. Failure to follow this instruction may result in personal injury.

Verify the customer concern.

Visually inspect for obvious mechanical or electrical faults.

If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index.

Symptom chart

Symptom	Possible source	Action
Poor performance (off-boost)	Low/Contaminated fuel Restricted intake air system General engine condition Engine control module (ECM) failure	Check the fuel level and condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for restriction. Check the engine condition, compressions, etc if there are indications of a mechanical fault. Check for DTCs indicating a module fault. Refer to the warranty policy and procedures manual if an ECM is suspect.
No boost	Electrical connections and harnesses Restricted intake air system Charge air cooler restricted/leaking Turbocharger actuator failure(s) Turbocharger failure(s) Engine control module (ECM) failure	Check the electrical connections and harnesses. Check the intake air system for restriction/leakage. Check the turbocharger actuators and circuits. Refer to the electrical guides. Check the turbochargers for wear. Disconnect the turbocharger intake and outlet pipework and turn the turbochargers by hand. Any roughness indicates a fault. Check any up and down movement in the turbocharger shafts. Excessive movement indicates a fault. If in doubt, compare the suspect unit with a new turbocharger. Check for DTCs indicating an actuator or module fault. Refer to the warranty policy and procedures manual if an ECM is suspect.
No boost/excessive noise	Turbocharger failure(s)	Disconnect the turbocharger intake and outlet pipework and turn the turbochargers by hand. Any roughness indicates a fault. Check any up and down movement in the turbocharger shafts. Excessive movement indicates a fault. If in doubt, compare the suspect unit with a new turbocharger.

DTC index

NOTES:

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).
