Warranty - Diagnostic Trouble Code Report
Bulletin: W96-007Section: Warranty
Date: 5/20/96
Model: Discovery, 4.0SE, 4.6 HSE
Applicable to: USA/CND
Subject:
4.0 SE, 4.6 HSE AND 4.0 DISCOVERY MIL LIGHT "P" CODES
GEMS FAULT:
In Service Bulletin W95-002, we requested that up to four of the labor codes contained on the included list be claimed for all repairs related to the GEMS system where fault codes have been stored in the ECM. Commencing with this bulletin, all warranty claims relating to the correction of a MIL event must include up to four of the labor codes associated with a MIL event and a Drive Cycle operation (either A, B or C).
In order to provide us with essential product information, the Diagnostic Trouble Code Report (DTCR), copy included, must be completed and faxed to 301-731-9814, whether you have found the root cause of the "check engine light" coming on or not.
Please note each "P" code now has one of three drive cycles associated with it. Below is a description 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. As only one drive cycle can be claimed per MIL event, select the longest drive cycle for the fault codes stored in the ECM and claimed through the warranty system. At the end of each drive cycle, do not switch off the ignition, but recheck for faults with TestBook.
Drive cycle A:
Time: 48 minutes (.80 hrs.)
Operation number: 19.22.98
MFI TestBook Test/Hookup to determine actual customer faults
Complete and fax the DTCR
Fix problem (extra time may be claimed)
Then:
Ignition on for 30 seconds
Engine start
Engine idle for 2 minutes
Engine Coolant Temperature (ECT) less than 140°F(60°C)
Hook up TestBook, check for fault codes
Drive cycle B:
Time: 63 minutes (1.05 hrs.)
Operation number: 19.22.97
MFI TestBook Test/Hookup to determine actual customer faults
Complete and fax the DTCR
Fix problem (extra time may be claimed)
Then:
Ignition on for 30 seconds
Engine start
Engine idle for 2 minutes
Engine Coolant Temperature (ECT) less than 140°F (60°C)
2 light accelerations,
0 to 35 mph 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:
Time: 75 minutes (1.25 hrs.)
Operation number: 19.22.96
MFI TestBook Test/Hookup to determine actual customer faults
Complete and fax the DTCR
Fix problem (extra time may be claimed)
Then:
Ignition on for 30 seconds
Engine start
Engine idle for 2 minutes
Engine Coolant Temperature (ECT) less than 140°F (60°C)
2 light accelerations,
0 to 35 mph 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
Gems Fault Example:
TestBook 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 operations should be claimed:
You may claim the above labor operations regardless of whether or not any GEMS repairs have been effected.
E.A.T. FAULT:
If, when diagnosing a M.I.L. illumination, any of the following codes are encountered; P1775, P1776 or P1777 then the diagnosis must be performed with the gearbox diagnostic in TestBook. Included is a list of labor codes that have been developed for the Electronic Automatic Transmission (E.A.T.) which relate to the fault codes stored in the gearbox diagnostic. These are used in the same manner as the GEMS "P" codes.
E.A.T. Fault Example:
TestBook 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 gearbox diagnostic is then consulted and it is found to be holding any of the fault codes on the included E.A.T. P codes list. The example shows how an E.A.T. code 23 would be claimed. Up to four E.A.T. codes stored in the ECM and a drive cycle can be claimed in conjunction with a MIL illumination. In addition to any necessary repairs, the operations should be claimed:
You may claim the above labor operations regardless of whether or not any E.A.T. repairs have been effected.
Since releasing Service Bulletin W95-002, we have found that most codes are only noted in the comment section of the warranty claim instead of being claimed as scheduled labor. In order for us to expedite the payment of claims and also retrieve valuable product information, it is essential that the "P" and "E.A.T." code labor operations be utilized as outlined, the DTCR is faxed (to 301 731 9814) and the drive cycle completed.
