G.30.B.25)
E0045-06 - Current Sense Bin Covers Short Circuit
Cause:
The bin covers motor (M-12) circuit indicates high current draw.
Possible failure modes:
1. Circuit connection shorted.
2. Excessive mechanical load on motor.
3. Controller internal failure (internal regulator failure).
Solution:
1. Enter the InfoView Monitor - service info screens
SYMPTOM

A. Record and erase service history.
Start the combine and operate concave clearance and bin covers circuits in both directions.
Record in which direction(s) the concave clearance increases or decreases.
Reload error history.
Check for the following fault codes: E0044-06, E0045-06, E0078-05 and E0079-05.
Use the following table to determine the location of the fault.
2. The concave clearance adjustment motor is bound up.
A. See the appropriate service manual chapter for repair.
3. The concave clearance motor operates in one direction only. Fault codes indicate a short to ground. Disconnect
the concave clearance motor connector X176.
A. Measure the resistance on connector X176 between pin A and pin B. The proper resistance range for the
coil is 1.0 - 5.0 ohms. If out of specification replace concave motor.
B. If the motor coil resistance is within specification continue with Step 4.
4. Measure the resistance on connector X176 between pin A and chassis ground. Flex the main frame harness
while making this check.
