Powertrain Control Module - Installation

6.7L DIESEL






NOTE: Do not apply paint to Powertrain Control Module (PCM) or a poor ground will result.

1. Install PCM (3) to the engine block. Tighten bolts (1 and 2). to 24 Nm (18 ft. lbs.).





2. Check pins in electrical connectors for corrosion, damage or dirt intrusion. Also, check all the PCM pins for being bent. Repair as necessary. Damaged, dirty, bent or corroded pins could result in poor conductivity, causing intermittent electrical issues or DTC's.
3. Clean pins in electrical connectors with an electrical contact cleaner.
4. Install PCM harness connectors (3) and harness retainer (1) to PCM (4).

5. Connect both negative battery cables.
6. Program the PCM PCM/ECM Reprogramming
7. After programming the PCM, allow the module to fully power down. This process will require 10 minutes for automatic transmission vehicles, or 75 seconds for manual transmission vehicles.

NOTE: Vehicles having 6.7L diesel engine with automatic transmissions will require a transmission quick learn after programming the PCM.

8. Use a diagnostic scan tool to erase any Diagnostic Trouble Codes (DTC's) from PCM.

FUEL INJECTOR ID CORRECTION CODES:





Each fuel injector has a six-digit alphanumeric correction code. The correction code is printed on the intake side of the fuel injector (1) and is used to identify injector calibration. When replacing any fuel injectors, this code must be entered into the vehicles Powertrain Control Module (PCM) using a diagnostic scan tool. In addition, if a new PCM is installed, use a diagnostic scan tool to program all six of the injector codes from the original fuel injectors into the new PCM.
