NOTE:
The JR 2.0L/2.4L and the 2.7L are equipped
with the Powertrain Control Module and
Transmission Control Module combined in a
single control module. This module is the
Next Generation
DaimlerChrysler and will be referred to as the
Powertrian Control Module (PCM).
The PCM has four color coded connectors C1
through C4, (C1 - BLK, C2 - ORANGE C3 -
WHITE, C4 - GREEN), with each connector
containing 38 pins.
Two tools are required to diagnose and repair
the PCM terminals and harness connectors:
1. Miller #3638 Terminal Removal Pick must
be used to release
terminals or harness and connector
damage will occur.
2. Miller #8815 Pinout Box must be used to
probe the PCM terminals or terminal
damage will occur.
