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.

1) "Continuous" under the "Time Required" column indicates that the specified test cycles at a frequency greater than once every 0.5 seconds whenever the
test entry conditions are met.
2) "Once per driving cycle" under the "Time Required" column indicates that the specified test will complete during the first 2 bags of an FTP as well as under
the test entr
y conditions specified, on the road.
3)All test entry condition parameters are measured instantaneously unless otherwise indicated.
p) If a 6 hour soak is met, some strategies will not require another continuous 6 hour soak if the customer performs a brief key-off. This has been put into
effect to improve evap monitor completion frequency.
q) Some strategies will have the ability to base evap monitor soak length on the CARB cold soak criteria which consists of an ECT range and ACT/ECT
differential.
r) A minimum soak time has been added to CARB's cold soak criteria (footnote q) to allow calibrators to set a minimum soak time if longer soak times are
n
eeded than given by the ACT/ECT-based CARB soak criteria.
a) A pending code will be stored after a malfunction has been detected on one driving cycle; a DTC will be stored after the same malfunction has been detected on the second consecutive driving cycle. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been
extinguished for the DTC.b) A DTC will be stored immediately upon detection of a malfunction. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for the DTC.k) A DTC will be stored after a malfunction has been detected on one drive cycle.The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for that DTC.l) A DTC will be stored after a malfunction has been detected on six consecutive drive cycles. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for that DTC.o)For intake air temperatures below 20 deg F, no DTC will set for indicated AIR malfunction.
s) A DTC will be stored after an evaporative system leak has been detected and the refueling debounce check has been completed on the subsequent
driving cycle
c)The MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles.
The MIL will be extinguished after three consecutive driving cycles where the monitor was run without a malfunction.d)The MIL will blink immediately upon detection of a misfire rate that exceeds the catalyst damage threshold, regardless of whether fuel is shut off or not.
If the misfire rate drops below the catalyst damage threshold, the MIL will stay on solidly.
The MIL will be extinguished after three consecutive drive cycles where similar conditions have been seen without the malfunction.e)The MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles.
The MIL will be extinguished after three consecutive drive cycles where similar conditions have been seen without the malfunction.f)For intake air temperatures below 32 deg F, the MIL will not illuminate for the indicated EGR DTCs.
For barometric pressures below 22.5"Hg, the MIL will not illuminate for the indicated EGR DTCs.
For intake air temperatures below 20 deg F, the MIL will not illuminate for the indicated AIR DTCs.
This prevents false MIL illumination due to ice in the EGR hoses or AIR switching valve(s).g)This monitor employs EWMA.
