Comprehensive Component Monitor - Automatic Transmission
General
The MIL is illuminated for all emissions related electrical component malfunctions. For malfunctions
attributable to a mechanical component (such as a clutch, gear, band, valve, etc.), some transmissions are
capable of not commanding the mechanically faile d component and providing the remaining maximum
functionality (functionality is reassessed on each power up). In such case a non-MIL Diagnostic Trouble
Code (DTC) will be stored and, if so equipped, a Transmission Control Indicator Light (TCIL) will flash.
For example on the CD4E transmission, if a gear ratio is not properly obtained and verified due to a
mechanical malfunction, the unobtainable gear is no longer commanded for that power up, the DTC is
stored and the TCIL flashes.

6HP26 Automatic Transmission
This transmission is operated by a stand-alone transmission control module (TCM). The MIL related
Diagnostic Trouble Codes will be transmitted via CAN to the Engine Control Module (ECM), and the
MIL illuminated, for all emissions related electrical and mechanical component malfunctions. For
malfunctions attributable to a mechanical component, this transmission may be capable of not
commanding the mechanically failed component a nd providing the remaining maximum functionality
(functionality may be reassessed on each power up). The TCM may be interrogated for transmission
information attributable to setting either code. The TCM Diagnostic Trouble Codes are addressed via a
separate document enclosed.
Auto Shift Manual (ASM) Transmission
The ASM system is based around a standard manual transmission with a clutch and mechanical selection
of a set range of gear ratios (in this case 6 speeds). In this application both clutch and gear selection
operations are controlled via a Transmission Contro l Module (TCM) which commands hydraulic actuators
based on commands from a number of inputs.
The driver actions of depressing and releasing the clutch pedal to control clutch actuation and the shifting
of gears using a gear lever have, in essence, been re placed by a TCM, hydraulic actuators and electronic
switches.
With ASM the demand to shift gears can either be direct from the driver (as in a conventional manual
transmission), or controlled automatically by the system based on parameters such as road speed, current
gear selected and throttle demand.
The MIL is illuminated for all emissions related electrical component malfunctions. For malfunctions
attributable to a mechanical component (such as a cl utch, gear, actuator, etc.), functionality is reassessed
on each power up. In such case a non-MIL or MIL Diagnos tic Trouble Code (DTC) will be stored and, if
so equipped, a Transmission Control Indicator Light will activate and/or a message will be displayed. For
example on the ASM transmission, if a gear selection is not properly obtained and verified due to a
mechanical malfunction, then the amber Transmission Control Indicator Light will activate and the
message center will display 'GEARBOX FAULT'. In addition, the powertrain MIL will activate and a
DTC will be stored. The TCM Diagnostic Trouble Cod es are addressed via a separate document enclosed.

Serial Data Link MIL Illumination
The instrument cluster on some vehicles use the J1850 serial data link or CAN data link to receive and
display various types of information from the PCM. For example, the engine coolant temperature
information displayed on the instrument cluster com es from the same ECT sensor used by the PCM for all
its internal calculations.
These same vehicles use the J1850 serial data link or CAN data link to illuminate the MIL rather than a
circuit, hard-wired to the PCM. The PCM periodically sends the instrument cluster a message that tells it
to turn on the MIL, turn off the MIL or blink the MI L. If the instrument cluster fails to receive a message
within a 5-second timeout period, the instrument cluster itself illuminates the MIL. If communication is
restored, the instrument cluster turns off the MI L after 5 seconds. Due to its limited capabilities, the
instrument cluster does not generate or store Diagnostic Trouble Codes.
