Fault Codes Corrections Bosch Engine Management System

AFFECTED VEHICLE RANGE:

RANGE ROVER (LP) 1999 Bosch

DISCOVERY (LT) All

SITUATION:

In some cases the code "P1000" appears stored in the Bosch engine management controller viewed with TestBook, when other codes should be displayed. This is the result of incorrect information on the Testbook CD. A number of other codes are also being displayed incorrectly. It is necessary when one of these codes is obtained to look at BOTH the P-code and the "Rover Reference" to determine what the correct code should be.

RESOLUTION:

INTERPRETATION OF INCORRECT FAULT CODES

A table has been produced as a cross-reference to correct P-codes to assist in interpretation of the information contained in the various faults which give incorrect P-codes.

The "Rover Reference" must be read as a cross-reference to the correct descriptions and fault codes.

PARTS INFORMATION:

NO PARTS ARE INVOLVED

WARRANTY CLAIMS:

Normal warranty policy and procedures apply

PROCEDURE:

DETERMINE THE UNDERLYING MEANING OF THE P1000 CODE





1. Refer to Figure 1 and identify the "Rover Reference" code. Use this code to identify the underlying meaning of the "P1000" Code.

2. When a "P1000" Code is found on TestBook, refer to the following table to interpret the underlying meaning of the code.





3. If "P0122","P0136", "P0144" or "P0177" display, refer to the table for correct interpretation of the fault codes.
