TUBE ASSEM. 2V3919 - Caterpillar

Electronic Control Module (ECM)
Before the ECM is replaced, ensure that replacement is necessary. The ECM is seldom the cause of a fault. Always check that power is available to the ECM. Battery voltage is required between contacts J1-1 and J1-2 of the machine harness connector for the ECM. Continue ONLY if all other attempts to isolate the problem have failed. Always consult the technical communicator at your dealership for a possible consultation with Caterpillar. This consultation may greatly reduce the time that is required for a repair.
