Warranty Claims - MIL Event Requirements
Bulletin: W97-007Section: Warranty
Date: 27 June 1997
Model:
Applicable to: USA/Cda
Subject: 4.0/4.6 Range Rover and 4.0 Discovery MIL Light "P" Codes
GEMS Fault Diagnostic Trouble Code (DTC) Labor Codes:
In Service Bulletin W96-007, LRNA requested that up to four DTC labor codes from the attached list be claimed for all repairs related to the GEMS system where diagnostic trouble codes were stored in the ECM.
Since releasing Service Bulletin W96-007, we have found that DTC's are frequently not listed or only noted in the comment section of the warranty claim instead of being claimed as scheduled labor. It is also evident that a drive cycle only is being claimed on some warranty claims with no information t6 back up what the stored DTC's were.
In order to expedite the payment of claims and also retrieve valuable product information the Diagnostic Trouble Code Report (DTCR) must be completed and faxed to 301-731-9814. The report must be faxed whether you have found the root cause of the illuminated check engine light" or not.
Effective with this bulletin all warranty claims relating to the correction of a MIL event must include the following;
^ A Drive Cycle labor operation (either A, B, C or D).
^ A minimum of one and a maximum of four of the DTC labor codes associated the MIL event.
^ Any relevant information relating to the claim in the comments section.
^ The DTCR must have been faxed to LRNA at 301-731-9814
Drive Cycles
Each DTC now has one of four drive cycles associated with it. On the following pages are descriptions of each drive cycle and the time it should take to complete. A drive cycle may be included at the completion of any repair for a MIL event to ensure the problem is fixed and customer satisfaction is achieved. Only one drive cycle can be claimed per MIL event. Select the drive cycle of the required length to verify repair of the DTC's stored in the ECM and claim that drive cycle through the warranty system.
REMEMBER:
DO NOT TURN OFF THE IGNITION AT THE END OF A-DRIVE CYCLE. RECHECK FOR FAULTS WITH TEST BOOK.
Drive cycle A:
Operation number: 19.22.98
Time: 48 minutes (.80 hrs.)
^ MFI TestBook Test/Hookup to determine actual customer faults
^ Complete and fax the DTCR
^ Fix problem (extra time may be claimed)
Then perform the following:
^ Switch ignition on for 30 seconds
^ Ensure Engine Coolant Temperature (ECT) less than 140° F (60° C)
^ Start engine
^ Allow engine to idle for 2 minutes
Hook up Test Book, check for fault codes
Drive cycle B:
Operation number: 19.22.97
Time: 63 minutes (1.05 hrs.)
^ MFI Test Book Test/Hookup to determine actual customer fault
^ Complete ar6d fax the DTCR
^ Fix problem (extra time may be claimed)
Then perform the following:
^ Switch ignition on for 30 seconds
^ Ensure Engine Coolant Temperature (ECT) less than 140° F (60° C)
^ Start engine
^ Allow engine to idle for 2 minutes
^ 2 light accelerations (0 to 35mph with light pedal pressure)
^ 2 medium accelerations (0 to 45 mph with moderate pedal pressure)
^ 2 hard accelerations (0 to 55 mph with heavy pedal pressure)
^ Engine idle 2 minutes
Hook up TestBook, check for fault codes
Drive cycle C:
Operation number: 19.22.96
Time: 75 minutes (1.25 hrs.)
^ MFI Test Book Test/Hookup to determine actual customer faults
^ Complete and fax the DTCR
^ Fix problem (extra time may be claimed)
Then perform the following;
^ Switch ignition on for 30 seconds
^ Ensure Engine Coolant Temperature (ECT) less than 140° F( 60° C)
^ Start engine
^ Allow engine to idle for 2 minutes
^ 2 light accelerations (0 to 35mph with light pedal pressure)
^ 2 medium accelerations (0 to 45 mph with moderate pedal pressure)
^ 2 hard accelerations (0 to 55 mph with heavy pedal pressure)
^ 60 mph cruise for 5 minutes
^ 50 mph cruise for 5 minutes
^ Engine idle for 2 minutes
Hook up TestBook, check for fault codes
Drive cycle D:
NOTE:
During Drive Cycle "D" in the final phase of the cycle i.e. whilst driving at 35 mph, it will be necessary to find a straight piece of road to ensure that;
^ The speed does not drop below 35 mph
^ No traffic conditions are encountered which force the vehicle to stop
^ No excessive use of the throttle is used to maintain the 35 mph
^ Lifting off the throttle completely is not required
Operation number: 19.22.88
Time: 81 minutes (1.35 hrs.)
^ MFI TestBook Test/Hookup to determine actual customer faults
^ Complete and fax the DTCR
^ Fix problem (extra time may be claimed)
Then perform the following:
^ Switch ignition on for 30 seconds
^ Ensure Engine Coolant Temperature (ECT) less than 140° F (60° C)
^ Start engine
^ Allow engine to idle for 2 minutes
^ 2 light accelerations, (0 to 35mph with light pedal pressure)
^ 2 medium accelerations (0 to 45 mph with moderate pedal pressure)
^ 2 hard accelerations (0) to 55 mph with heavy pedal pressure
^ 60 mph cruise for 5 minutes
^ 50 mph cruise for 5 minutes
^ 35 mph cruise for 5 minutes
^ Engine idle for 2 minutes
Hook up TestBook, check for fault codes
Gems Fault Example:
Figure 1:
Test Book is connected to a vehicle with a complaint of "check engine light on". By following the test procedure, it is found that the ECM is holding fault codes 0300, 0301, 0336 and 1316. In addition to any necessary repairs, the shown operations should be claimed.
You may claim the above labor operations regardless of whether or not any GEMS repairs have been effected.
Electronic Automatic Transmission (EAT) FAULT:
If, when diagnosing a MIL illumination, codes P1775, P1776 or P1777 are encountered the diagnosis must be performed with the gearbox diagnostic in TestBook. Attached is a list of labor codes that have been developed for the Electronic Automatic Transmission (EAT) which relate to the fault codes stored in the Transmission Control Module (TCM). These are used in the same manner as the GEMS "P", codes.
EAT Fault Example:
Test Book is connected to a vehicle with a complaint of "check engine light on". By following the test procedure, the GEMS diagnostic is found to be holding code P1775. The TestBook Transmission diagnostic is then consulted and the TCM is found to be holding any of the fault codes on the attached TCM Diagnostic Trouble Code (DTC) list.
Image 2:
The following example shows how an TCM code 23 would be claimed. Up to four DTC's stored in the TCM and a drive cycle can be claimed in conjunction with a MIL illumination. In addition to any necessary repairs, the shown operations should be claimed:
You may claim the above labor operations regardless of whether or not any EAT repairs have been effected.
