Injector Codes Calibration using CAT ET Software
Injector Codes Calibration using CAT ET Software The Injector Codes Calibration function reads the programmed Injector Code from the ECM and changes the numeric four or six digit Code for each Injector. Each Injector Code should match the Code stamped on the Injector. Accessing (Injector Codes Calibration using CAT ET Software) To run the Injector […]
P0487 EGR Throttle Position Control Circuit (D6CC)
Component Location P0487 EGR Throttle Position Control Circuit General Description (P0487) DC motor type EGR actuator which is controlled by EDU module operates the EGR valve directly. ECM performs EGR system feed back control with the information of measured mass air flow. (The role of AMS in diesel engine is different from gasoline engine. Fuel […]

P0341 Cam Synchronization Error D6CA
Component Location P0341 Cam Synchronization Error General Description (P0341) Camshaft position sensor is installed on the cylinder head. Camshaft position sensor senses therevolution of cams haft by converting magnetic flux change into electric signal. Magnetic flux changes generate due to position change of tone wheel installed on the flywheel as magnetic inductive sensor type. Camshaft […]
Accessing Parameter Lockout on CAT ET Software
Accessing Parameter Lockout on CAT ET Software Accessing Parameter Lockout on CAT ET Software The Parameter Lockout function allows parameters to be locked so that they cannot be changed anywhere in the Service Tool by service Mechanics. To unlock the parameters, Factory or Customer Passwords are required. Accessing (CAT ET Software) To run the Parameter […]
P0611 Fuel Injector Control Module Performance D6CC
Component Location P0611 Fuel Injector Control Module Performance General Description The ECM judges whether vehicle condition is good or not through algorithm check-sum. All data of algorithm check-sum is composed of combination of “0” and “1”. The algorithm check-sum means that adds all values in the character row. The criteria to judge whether the ECM […]
Cold Mode on Status Flags CAT ET Software
Cold Mode on Status Flags CAT ET Software The ECM limits engine power during Cold Mode operation and the ECM modifies injection timing during Cold Mode operation. Cold Mode operation provides the following benefits: Increased cold weather starting capability Reduced warm-up time Reduced white smoke The Electronic Control Module (ECM) limits engine power during […]
Difference between throttle body on gasoline and diesel engines
Throttle body in Gasoline engine The ratio A/F optimal for gasoline to burn completely in the engine combustion chamber is 14.7/1 (14.7 grams of air / 1 gram of gasoline). Therefore on gasoline engines will depend greatly on the amount of air intake. ECM will calculate the amount of fuel injection based on the amount […]
P0601 Internal Control Module Memory Check Sum Error D6CC
Component Location P0601 Internal Control Module Memory Check Sum Error D6CC General Description The ECM judges whether vehicle condition is good or not through algorithm check-sum. All data of algorithm check-sum is composed of combination of “0” and “1”. The algorithm check-sum means that adds all values in the character row. The criteria to judge […]
What is boost pressure sensor (BPS)?
Boost pressure sensors are used in turbocharged engines to provide air pressure information and air and fuel ratios in order to regulate engine performance. As a complex piece of technology, a boost pressure sensor has been an impressive addition to engine technology. Boost pressure sensors control the boost level produced in the intake manifold of […]
