NOTE: The 2004 model year, LH, 300M, Intrepid and Concorde vehicles will integrate the Transmission Control Module and Powertrain Control Module into a single control module. This new module is called the Next Generation Controller (NGC) for DaimlerChrysler and will be referred to as the Powertrain Control Module (PCM). The Transmission Control System is part of the Powertrain Control Module. New Diagnostics procedures and New DTC's are some of the changes you will see which reflect the new combined module technology. The PCM will have four color coded connectors, C1 through C4, (C1-BLK, C2-GRAY, C3-WHITE, C4-GREEN), each PCM connector will have 38 pins each. Two new tools are used for probing and repairing the New PCM connectors. A New tool to release the pins from the PCM connectors Miller Tool #3638 is introduced, you must use the Miller Tool #3638 tool to release the connector pins or harness and connector damage will occur. Also a New tool for probing connectors Miller Tool #8815 is introduced, you must use the Miller tool #8815 tool to probe the PCM pins or harness and connector damage will occur. There are also new Verification tests and module replacement procedures for the new PCM.
