Inspection Maintenance Readiness Code


I/M readiness information indicates whether a full diagnos tic check has been completed, i.e. the minimum
number of driving cycles necessary for MIL illumination has been completed since computer memory was
last cleared. Information available to the test equi pment or diagnostic tool includes all the non-continuous
monitors. Misfire, Fuel System and CCM monitors are assumed to complete if all the non-continues
monitors have completed.

A P1000 DTC is stored after an OBD reset is performed, until the I/M readiness check is complete.



Tamper Protection


The AML EOBD System shall meet ISO DIS 15031-7 / SAE J2186 - Diagnostic Data Link Security
requirements, to write-protect any re-programmable co mputer code. Additional data will be stored in the
PCM Vehicle Identification Block to enable retrieva l of VIN (although VIN may not be in the VID block
for all vehicles), CALID (CALibration ID identifi es the specific calibration) and CVN (Calibration
Verification Number, similar to an encrypted check sum). CALID and CVN will be tracked for all initial
releases, running changes and field fixes.

To achieve this data retrieva l J1979 Mode 09 will be implemented for VIN, CALD and CVN.



Serial Data Link Connector

The connection between the vehicle and the diagnostic tester shall comply with ISO DIS 15031-3 / SAE
J1962. Whereby the connector will be located in the passenger compartment in the area bounded by the
driver's end of the instrument panel to 300mm beyond the vehicle center line, attached to the instrument
panel and accessible from the driver's seat, and permit one handed / blind insertion of the mating
connector.



Serial Data Link Communication Protocol

The Communication Protocol used by the AML EOBD system will conform to ISO DIS 15031-4 / SAE
J1850, Class B Data Communication Network In terface (41.6kbps) / ISO DIS 15765-4 Diagnostics on
Controller Area Network (CAN).

Basic diagnostic data and bi-directional control inform ation will be provided using the format and units as
described in ISO DIS 15031-5 / SAE J1979 and will be av ailable to Test equipment and diagnostics tools
meeting the requirements of ISO DIS 15031-4 / SAE J1850.

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.
