The ECM detects the following conditions: •The timer for the PTO has expired and the engine has shut down. Probable Causes: 1) ECM Connection/Harness2) PTO timer programmed incorrectly3) PTO timer operated correctly and shut down as it is programmed to do4) Check engine light or PTO switch on lamp failure5) Vehicle speed circuit/sensor6) PTO switch circuit/sensor CAT 3406E (Prefix 5DS or 1LW) Fault Code: 47 PID: 71 SPN: FMI: 1 Idle Shutdown CAT 3406E (Prefix 5DS or 1LW) Fault Code: 46 PID: 100 SPN: FMI: 11 Very Low Oil Pressure CAT 3406E (Prefix 5DS or 1LW) Fault Code: 46 PID:...

This condition indicates that the battery circuit to the Engine Control Module (ECM) has a battery condition that is intermittent while the engine is running. If battery voltage disappears without returning, the ECM will not log this diagnostic code and the engine will shut down. The ECM detects the following conditions: •The ignition key switch is in the ON position.•The engine is running.•The engine is not cranking.•The ECM has been powered for at least three seconds. The ECM will detect one of the following conditions: •The battery voltage drops below 6 VDC for at least 0.50 seconds.•Three voltage readings in...
