NOTE:
Clearing the PCM Diagnostic Trouble Codes (DTCs) erases any PCM recorded freeze frame data. Record any PCM freeze frame information before proceeding.
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
Refer to Wiring Diagrams ELECTRONIC ENGINE CONTROLS - 3.0L DIESEL for schematic and connector information.
