Diagnostic Codes Table
Code and Description Conditions which Generate this Code System Response
444-5 Starter Motor Relay : Current Below Normal The Electronic Control Module (ECM) detects an open circuit and/or a short to the +Battery in the start relay. The ECM can only detect this condition when the start relay is not energized. The code is logged.
444-6 Starter Motor Relay : Current Above Normal The ECM detects a short circuit to ground in the start relay. The ECM can only detect this condition when the start relay is energized. The ECM has the ability to crank the engine when the Engine Control Switch (ECS) is placed in the START position. After the ECS is placed in the START position, the ECM will begin the prelube cycle. The ECM will send an engine start signal to terminal BH of the customer connector after the prelube cycle is complete. The customer's engine start signal will return on terminal BJ of the customer connector. The signal is then sent to terminal f of the A-C90/P-C1 connector on the power distribution panel.The crank cycle will continue for the cycle crank time that has been programmed or the crank cycle will continue until the engine speed reaches the crank terminate speed.This process will repeat for a programmed amount of times "Total Number of Crank Cycles". If the engine does not start, Caterpillar Electronic Technician (ET) will display "OVERCRANK". The engine control will be in an idle state. The process can be restarted by turning the ECS to the OFF position. Next, turn the ECS to the STOP position. Then turn the ECS to the START position.The engine can be manually started by using the "crank override switch" which is located on the inside of the instrument panel.
