This Special Instruction provides additional information that is needed to use the Customer Communication Module (CCM) on the Series 3500 and Series 3600 gas engines. For installation of the CCM and general information on the CCM, refer to the Operation and Maintenance Manual, SEBU6874, "Customer Communication Module (CCM) for Diesel Engines". All information in this Special Instruction supersedes any information in the Operation and Maintenance Manual, SEBU6874, "Customer Communication Module (CCM) for Diesel Engines". For example, the programming format for IID $00 should be taken from this Special Instruction, NOT Operation and Maintenance Manual, SEBU6874, "Customer Communication Module (CCM) for Diesel Engines".Programming Information
Parameter Identifiers (PID) for the G3500B ECM and the G3600A+ ECM
Each PID has a 1, 2, or 3 byte identifier (given in hexadecimal). The PID is followed by one or more data bytes. An example of the engine rpm PID is $00 $40. The PID is followed by 2 bytes of data (aa) that contain the current engine speed. Data bits are displayed in binary digits unless the number is preceded by $. All data is sent with the most significant byte first.The following chart is a quick reference list of the Parameter Identifiers (PID) along with a brief description.Parameter Identifier Reference Chart

Quick PID Reference for G3500B and G3600A+ Applications    
PID    Code Description    Definition    
$00 $03
a     Detonation     Used to read the relative level of engine detonation.    
$00 $40
aa     Engine RPM     Used to read the engine rpm.    
$00 $41
aa     Actual Engine Timing     Used to read the actual engine timing as the angular difference between cylinder ignition and cylinder at TDC.    
$00 $44
aa     Engine Coolant Temperature     Used to read the engine coolant temperature.    
$00 $46
aa     Desired Engine Speed     Used to read the desired engine speed of the engine controller.    
$00 $47
aa     First Desired Timing     Used to read and program the first desired timing. The first desired timing is the base desired timing when the timing setting 2 switch is open.    
$00 $54
aa     Engine Oil Pressure (gauge)     Used to read the gauge oil pressure of the engine.    
$AA $FA0D
abcd     Activate Diagnostic Broadcast     Used to request diagnostic broadcast
