Accumulating Powertrain Control Module (PCM) Data

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Ford RV Cutaway, 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.

PCM data can be accumulated in a number of ways. Gather as much data as possible when the concern is occurring to prevent misdiagnosis. Data should be accumulated during different operating conditions and based on the customer description of the intermittent concern. Reference the known good data values located in the REFERENCE VALUES article Control System Diagnostic Sheet Reference. This requires recording data in 4 conditions for comparison: 1) Key On Engine Off (KOEO), 2) Hot Idle, 3) 48 km/h (30 mph), and 4) 89 km/h (55 mph). Acquisition of PCM PID data using a scan tool is one of the easiest ways to gather information.

For information on the functions of your scan tool, refer to the manufacturer's manual for scan tool instructions.

Below is a list of the functions available:
