Information:
System Operation Description:Use this procedure in order to troubleshoot the Engine Control Switch (ECS). Or use this procedure if the diagnostic code in Table 1 is active or easily repeated.
Table 1
Diagnostic Codes Table
J1939 Code and Description Conditions which Generate this Code System Response
1656-2 Engine Automatic Start Enable Switch : Erratic, Intermittent, or Incorrect The two inputs from the ECS are in the opposite state. The code is logged. The 1656-2 diagnostic code is generated when the two start/run/stop inputs to the Engine Control Module (ECM) are not complementary. The status for the Engine Control Switch will display "Abnormal/Incorrect Data" while the fault is active. The Electronic Modular Control Panel 4 (EMCP 4) controls the starting and stopping of the engine. The engine parameters for the total number of crank cycles and the engine cooldown must be programmed to zero (0).The following inputs for the engine control are located on the panel for the EMCP 4: "RUN", "AUTO" and "STOP". These switches control a primary input and a secondary input to the ECM. The primary input to the ECM is over the J1939 data link. The secondary input is a set of relay contacts in the EMCP 4 that are normally open to digital return. If the primary input is lost, the ECM will look to the secondary input. The engine parameter for the secondary input must be set to the enabled state in order for the secondary input to be recognized. When the "RUN" switch is pushed, the panel for the EMCP 4 the start/run/stop inputs 1 and 2 to the ECM are pulled low. If the signals to the start/run/stop input of the ECM are in opposite states, the ECM determines that one of the signals is faulty. When one of the signals is faulty, the ECM will keep the last good input. When the diagnostic code activates and the switch is in the "STOP" position, the engine will not start. When the diagnostic activates and the switch is in the "RUN" position, the engine will continue to run.

Schematic for the ECS with EMCP 4
Test Step 1. Inspect the Electrical Connectors and the Wiring
Set the EMCP 4 to the STOP position.
Turn the main disconnect switch to the OFF position.
