Table 1
Histograms for C11 – C32, 2005 and Up engines    
Histogram Parameter (units)    Trap Conditions    Sample Period (secs)    Number of Counters (does not include underflow and overflow counters)    Minimum (units)    Width (units)    Histogram Type    
2 Dimensional (counts vs. one parameter)     1        
Engine (over) speed (rpm)     Engine speed > 2500 rpm     8 2600     100     occurrence    
Coolant temperature (°C)     Engine speed > 400 rpm, and at least 30 seconds since engine running     14 50     5     time    
Intake air temp (°C)     1150 rpm < engine speed < 2250 rpm, and coolant temp > 75 °C, and fuel > 90%     12 40     5     time    
Boost pressure (KPa gauge)     1150 rpm < engine speed < 2250 rpm, and coolant temp > 75 °C, and fuel > 90%     12 80     10     time    
3 Dimensional (counts vs. two parameters)    
Engine speed (rpm)     Engine speed > 400 rpm and coolant temp > 75 °C     7 1000     200     time    
Engine load at current engine speed (%)     4 50 10     time    Note: The Engine (over) speed (rpm) histogram captures occurrences. But these occurrences, increment once every second. So the data displayed in this histogram is in seconds.Product Link
Products with Product Link installed can track the DTC history in Equipment Manager or Vision Link. The DTC history is not erased and this DTC history gives the DTC occurrence date and the occurrence counts at each report. Product Link also tracks the hours and the reports containing time/date stamp to determine when the DTCs are reported.VIMS
Products with VIMS installed can use the event chronological list to see the date/time and history of each DTC occurrence. This data can then be stored on a server or PC. This history does get erased from on-board when the data is downloaded.ECM Downloads
Products with ET availability can use ECM downloads. There are two types of ECM downloads that can be used to store the DTCs, histograms, and other information about a product. The Warranty Report or Product Status Report (PSR) can be easily downloaded and stored in Service Information Management Systems (SIMSi). The warranty report does not contain all the histograms. By default, the PSR does not include the histograms. But you can get the histograms with the PSR if you select the appropriate option in Caterpillar Electronic Technician (Cat ET) while downloading the PSR.Note: Dealers can get the instructions for downloading PSR from Cat ET page on https://dealer.cat.com.Note: Previous uploaded ECM downloads can only be accessed from the SIMSi website by the dealer who uploaded the ECM downloads.
