AML EOBD System Operation Summary
Rory O’Curry Aston Martin Lagonda CONFIDENTIAL 1 May 2009
[email protected] AML EOBD Monitors 07 ROC.doc Page 27 of 43
Comprehensive Component Monitor - Engine
General Inputs
Analog inputs such as Ambient Air Temperature (P0072, P0073), Intake Air Temperature (P0112, P0113),
Engine Coolant Temperature (P0117, P0118), Cylinder Head Temperature (P1289, P1290), Mass Air Flow
(P0102, P0103) and Manifold Absolute Pressure (P0107, P0108) are checked for opens, shorts, or out-of-
range values by monitoring the analog -to-digital (A/D) input voltage.
Analog Sensor Check Operation:
DTCs P0072, P0073, P0112, P0113, P0117, P0118, P0102, P0103, P0107, P0108,
P1289, P1290
Monitor execution continuous
Monitor Sequence none
Monitoring Duration 5 seconds to register a malfunction
Typical analog sensor check malfunction thresholds:
Voltage < 0.20 volts or voltage > 4.80 volts
On Vehicles fitted with Cylinder Head Temperature (CHT ) Sensors, 'Fail Safe Cooling' can be applied if
the cylinder head temperature is too high. The P1299 DTC will be set under these conditions.
Loss of Keep Alive Memory (KAM) power (a separate wire feeding the PCM) results in a P1633 DTC and
immediate MIL illumination.
Loss or corruption of the Vehicle Identification (VID) Block in the PCM results in a P1639 DTC and
immediate MIL illumination.
Ignition
Electronic Ignition systems (Electronic Distributorless Ignition System - EDIS or Coil on Plug - COP)
systems are used on all applications.
The EDIS system, located in the PCM, processes the 36 (or 40) tooth crankshaft position signal to
generate a low data rate PIP signal to control a 4 or 6 terminal 'double-ended' coil pack. The 'double ended'
coils fire a pair of spark plugs simultaneously - one is on its compression stroke, the other on its exhaust
stroke. The COP system also uses the EDIS system in the same way as described above, however each
sparkplug has it’s own coil which is fired only once on the compression stroke.
The ignition system is checked by monitoring three ignition signals during normal vehicle operation:
Profile Ignition Pickup (CKP, commonly known as PIP), the timing reference signal derived from the crankshaft 36-tooth wheel and processed by the EDIS system. PIP is a 50% duty cycle, square
wave signal that has a rising edge at 10 ° BTDC.
Camshaft IDentification (CMP, commonly known at CID), a signal derived from the camshaft to identify the #1 cylinder
