Customer Communication Module (CCM) for Diesel Engines Caterpillar

Parameter Identifiers for 3500B Engines

Usage:

PID Security Levels

The following chart defines the PID within each security level for 3500B applications. For 3500B systems the CCM will not automatically respond to a Write Request with a Write Response. Therefore, a Write Request (IID 34) should always be followed with a Read Request (IID 24) for verification after 1 second.

If the written value is greater than the maximum value of the parameter, the ECM will adjust the parameter to the maximum value allowed. If the written value is less than the minimum value of the parameter, the ECM will adjust the parameter to the minimum value allowed.

Each Parameter Identifier (PID) has an identifier that is one or two bytes in length. The identifier is hexadecimal. The PID is followed by one or more data bytes. For example, the Engine RPM PID is $00 $40. This PID is followed by two bytes of data (aa) that contain the status of the Engine Speed. Data bits are given as binary digits unless the number is preceded by $. All data is sent with the most significant byte (MSB) first.

The following chart is a quick reference list of the Parameter Identifiers (PID).
