E0043-06-Current Sense Lev Shoe Short Circuit (K.62.B.28.60 -
G.30.B.25)
E0043-06 - Current Sense Lev Shoe Short Circuit
Cause:
The Leveling shoe motor (M-03) circuit indicates high current draw.
Possible failure modes:
1. Circuit connection shorted to ground.
2. Excessive mechanical load on motor.
3. Controller internal failure (internal regulator failure).
Solution:
1. Enter the InfoView monitor - service info screens
Symptom
Leveling shoe
motor operates in
1 direction only
Leveling shoe motor
does not operate in
either direction
A. Record and erase service history
Start the combine, and shift the transmission in both directions.
Record in which direction(s) the transmission shift operates.
Reload error history. Check for fault codes E0043-06 and E0075-05.
Use the table above to determine the location of the fault.
2. The self leveling shoe mechanism is mechanically bound up, resulting in high current draw.
A. See the appropriate repair manual chapter for repair and adjustment of the self leveling shoe.
3. Fault codes indicate circuit fault due to short to ground. Disconnect shoe leveling motor connector X088. Mea-
sure between terminals D or E on connector X088 and a known good ground. There should be no continuity to
ground.
A. There is continuity to ground, indicating a short to ground in the motor. Replace the shoe leveling motor.
B. There is no continuity to ground. Continue with step 4.
4. Disconnect the batteries using the battery key. Use the multimeter to check for continuity between connector
X088 pin E and chassis ground.
A. If continuity is found, continue with step 5.
B. If no continuity is found, continue with step 6.
NOTE: The CCM module connects both sides of the circuit to ground when in neutral to "lock" the motor in
position. Power must be removed from the module prior to testing for short to ground condition on the motor
circuit to remove this ground path.
5. Disconnect inline connector X023. Use a multimeter to check for continuity between connector X023 pin 1 and
chassis ground.
A. If no continuity is found, the short to ground is in the lower frame (LF) harness between connector X023
pin 1 and connector X088 pin E wire 707 gray. Locate the short and repair.
