MASTER CYLINDER REBUILD KIT 6S9592 - Caterpillar

Diagnostic codes are displayed on the same display as the service hours, engine speed, battery voltage, engine oil pressure, and engine oil temperature. When a diagnostic code is displayed, the arrow that indicates which of the above parameters are displayed will be missing and a flashing "dIAG" will be displayed. If several faults are present, the diagnostic codes will be displayed in sequence. The diagnostic code can be cleared from the display by turning the Mode Control Switch (MCS) to the OFF/RESET position. Before attempting a repair, move the MCS to the OFF/RESET position and restart engine to see if problem recurs.Diagnosed Problems List
1. SCM Display = 01 dIAG, no magnetic speed pickup (speed sensor) signal.2. SCM Display = 02 dIAG, no oil pressure/temperature sensor (transducer) signal.3. SCM Display = 03 dIAG, a problem with inputs from the MCS.4. SCM Display = 04 dIAG, loss of set points programmed into the SCM memory.5. SCM Display = 05 dIAG, engine shut down with no shutdown command from the SCM.6. SCM Display = 06 dIAG, internal failure of SCM or unstable voltage supply.7. SCM Display = 07 dIAG, internal SCM programming switch does not match program.8. SCM Display = 08 dIAG, temperature probe problem.9. SCM Display = 09 dIAG, oil pressure probe problem. SCM displays high oil pressure when the engine is NOT running and has cooled down.
