Fault codes

CodeMeaningRemedy
i01197515SMCS Code: 1000• Check the crankcase oil level. Maintain the oil level between the “ADD” mark and the “FULL” mark on the oil level gauge. • If necessary, perform minor adjustments. Repair any leaks and tighten any loose bolts. • Note the service hour meter reading. Perform the maintenance that is in the Operation and Maintenance Manual, “Maintenance Interval Schedule”.

Symptoms & remedies

SymptomCauseRemedy
Gauge readings that change even if the readings are within specificationsSignificant change in the readingsDetermine the cause of any significant change in the readings, and/or correct the cause of any significant change in the readings. Consult your Caterpillar dealer for assistance.
Low oil pressure or no oil pressure is indicatedStop the engine and determine the cause of the problem. Refer to Troubleshooting for further information or consult with your Caterpillar dealer.
Engine operating above the normal range and steam becomes apparentReduce the load and the engine speed (rpm). Inspect the cooling system for leaks. Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load.
Decrease in fuel pressureA decrease in fuel pressure usually indicates a plugged fuel filter.
High exhaust temperatures Power loss Excessive fan usage Reduction in fuel economyAirflow restriction can cause these conditions.If an airflow restriction device must be used, the device should have a permanent opening directly in line with the fan hub. The device must have a minimum opening dimension of at least 770 cm2 (120 in2). A centered opening that is directly in line with the fan hub is specified in order to prevent an interrupted airflow on the fan blades. Interrupted airflow on the fan blades could cause a fan failure. Caterpillar recommends a warning device for the inlet manifold temperature and/or the installation of an inlet air temperature gauge. The warning device for the inlet manifold temperature should be set at 65°C (150°F). The inlet manifold air temperature should not exceed 65°C (150°F). Temperatures that exceed this limit can cause power loss and potential engine damage.
