Comprehensive Component Monitor - Manual Transmission.

General.

The MIL is illuminated for all emissions relate d electrical component malfunctions. A manual
transmission vehicle will have either a Vehicle Speed Sensor (VSS) or an Output Shaft Speed Sensor
(OSS). The MIL will illuminate if the speed signal is declared as zero when the vehicle is inferred to be
moving.

Transmission Inputs

Vehicle Speed Sensor Check Operation:
DTCs P0500
Monitor execution continuous
Monitor Sequence none
Monitoring Duration 30 seconds

Typical VSS check entry conditions : Minimum Maximum
Load 0.5
Engine rpm 1900 rpm 4500 rpm

Typical VSS malfunction thresholds:
Vehicle is inferred to be moving with positive driving torque for 5 seconds.


Output Shaft Speed Sensor Functional Check Operation:
DTCs P0720
Monitor execution continuous
Monitor Sequence none
Monitoring Duration 30 seconds

Typical OSS check entry conditions : Minimum Maximum
Load 0.5
Engine rpm 1900 rpm 4500 rpm
Output shaft rpm 100 rpm

Typical OSS functional check malfunction thresholds:
Vehicle is inferred to be moving with positive driving torque and OSS < 100 to 200 rpm for 5 seconds.


Manual Transmission CCM temporary disablement conditions (other than entry requirements) :
None.

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.
