ReferenceSpecial Instruction, REHS3819, "Procedure for Troubleshooting and Cleaning the Oil Rail System for the Hydraulic Electronic Unit Injector (HEUI)"

ReferenceService Magazine, SEPD0993, "A Hotline for the Fuel Systems for Hydraulic Electronic Unit Injectors (HEUI) Is Now Available"

The diagnostic documents for troubleshooting the systems of the Hydraulic Electronic Unit Injector (HEUI) have been revised in order to provide significantly improved diagnostic methods. Adherence to the updated diagnostic flow chart is required. Deviations from the correct sequence of the process may cause additional diagnostic time and a result in a claim that will not be paid. The resulting test data that is captured during the use of the procedures is now required to be included with a report for the warranty claim. Refer to the Special Instruction above for the correct procedures.

Also, a new "HEUI Hotline" has also been established in order to support questions from the field. A technician from the "HEUI Hotline" may provide an authorization number. The authorization number guarantees that your warranty claim will be paid. Refer to the Service Magazine above for more information on the "HEUI Hotline".

A new "Tech Tips" that is dated 30June 2009 is available. The "HEUI Hotline" and the changes to the diagnostic procedures are explained in the "Tech Tips". The related information and the "Tech Tips" are located on the following AVSpare web site. The address is located below.
