E0016-03-Clean Grain Elevator RPM Shorted To High Source
(K.60.B.95.81 - G.30.B.54)
E0016-03 - Clean Grain Elevator RPM Shorted To High Source
Cause:
The clean grain elevator RPM sensor (B08) circuit is shorted to a higher than normal voltage source.
Possible failure modes:
1. Sensor supply wiring shorted to 12 volts.
2. Controller internal failure (internal regulator failure).
Solution:
1. Enter the InfoView Monitor - Dealer Diagnostics screen.
Select "Clean Grain" sub menu.
Select "Clean Grain Elevator RPM" and check voltage range.
The proper voltage sensor blocked by ferrous metal - 5.6 - 7.3 volts
The proper voltage sensor unblocked by ferrous metal - 0.5 - 5.6 volts
A. If the voltage reading is high out of range continue with Step 2.
B. If the voltage reading is within the proper limits, since the shorted wire may not be powered up at this time.
Continue the troubleshooting at Step 3.
2. The voltage reading on the InfoView is high. Disconnect the clean grain elevator RPM sensor connector X182.
A. If the voltage drops to 7.3 - 9.0 volts the short is in the sensor, or sensor wiring. Replace the sensor.
B. If the voltage remains high on InfoView display the short circuit is somewhere between connector X182
and connector X019 J2-28 on CCM1 in the main frame harness wire 450 yellow.
3. Operate the clean grain elevator and monitor the InfoView voltage readings.
A. If high voltage reading is viewed continue with Step 2.
B. If a high voltage reading cannot be generated erase the fault code and continue operation.
