REPAIR PROCEDURE

CHECK FOR DIAGNOSTIC TROUBLE CODES

NOTE:

Before continuing, check for any previous repair history relating to fault codes P003C or P003E and ensure that there are no electrical issues

with the wiring and connectors between the Engine Control Module (ECM) and the Camshaft Profile Switching (CPS) solenoids (banks A

and B) and the supply voltage to both CPS solenoids.

NOTE:

If there are additional fault codes stored in the ECM other than POO3C or P003E, they should be diagnosed / rectified and all fault codes

cleared and the vehicle re-assessed to see if the codes return. If the P003C / P003E codes return without any additional codes stored in the

ECM, continue with the Repair Procedure. If the codes P003C / P003E and or additional codes appear in the ECM continue with diagnosis

using SDD and do not follow the Repair Procedure below.

CAUTION:

Ensure all ignition "ON" / ignition "OFF" requests are carried out; failure to perform these steps may cause damage to control modules in the

vehicle.

CAUTION:

A Land Rover-approved Midtronics Vehicle Power Supply must be connected to the vehicle battery during IDS diagnosis / module

programming.

1. Connect the Land Rover-approved Midtronics Vehicle Power Supply to the vehicle battery.

NOTE:

IDS must be loaded with IDS-DVD124_V6.O1 or later and Calibration File 59 or later.

2. Connect the IDS to the vehicle and begin a new Symptom Driven Diagnostics (SDD) session.

3. Follow the on-screen prompts, allowing SDD to read the VIN and identify the vehicle.

4. From the Session Type selection screen, choose Diagnosis~.

5. Select Complete vehicle - read all diagnostic trouble codes~.

^ If DTC POO3C or POO3E is stored in the ECM in addition to other related codes, carry out diagnosis of all codes using SDD as a separate

claim and then return the vehicle to the customer.

^ If DTC P003C or P003E is stored in the ECM without additional related codes, continue to INSTALL NEW OIL RESTRICTORS below.

^ If DTC P003C and P003E are both stored in the ECM without additional related codes, refer to Workshop Manual, section 303-00: Engine

System Diagnosis, and check for correct engine oil pressure, if necessary; to be carried out as a separate claim.

> Clear all DTCs.

> Start engine; let run for two minutes.

> Turn engine 'OFF'.

> Read all diagnostic trouble codes.

> If POO3C and / or P003E are stored in the ECM, continue to INSTALL NEW OIL RESTRICTORS below.

> If P003C and / or P003E are not stored in the ECM, return vehicle to the customer.

6. Exit the current session.

7. Disconnect the IDS and the Midtronics Vehicle Power Supply from the vehicle.

INSTALL NEW OIL RESTRICTORS

1. Refer to Workshop Manual section 303-01B and install a new oil restrictor in both A and B banks.
