F 250 2WD HD Pickup V8-7.3L DSL Turbo VIN F (1997)
Engine Control Module: Reset Procedure
DESCRIPTION
The Powertrain Control Module (PCM) Reset allows the scan tool to command the PCM to clear all emission-related diagnostic information. When
resetting the PCM, a DTC P1000 will be stored in the PCM until all the OBD II system monitors or components have been tested to satisfy a drive
cycle, without any other faults occurring. For more information about a drive cycle, refer to Drive Cycles. Clearing codes from the vehicle-specific
RETRIEVE/CLEAR CONTINUOUS CODES will clear all systems, except the Injector Driver Module (IDM), including OBD II systems. Refer to
Key On Engine Off (KOEO) On-Demand Self Test for information on clearing IDM codes. Clearing codes from the OBD II generic menu will only
clear OBD features for the 7.3L diesel.
The following events occur when a PCM reset is performed:
-
Clears the number of Diagnostic Trouble Codes (DTC).
-
Clears the DTCs.
-
Clears the freeze frame data.
-
Resets status of the OBD II system monitors.
-
Sets DTC P1000 as a vehicle-specific DTC. P1000 will not appear as an OBD II code.
NOTE: This procedure is written assuming the use of a New Generation STAR (NGS) Tester. If a generic OBD II scan tool is used, it will be
necessary to follow the instructions supplied by the manufacturer of the scan tool.
