E0033-05 - Lateral Inclination Sens Line Disconnected
NOTE: This troubleshooting chart is for CX combines Series 1206 - 1237 only.
Cause:
The lateral inclination sensor (B-02) circuit is open or shorted to ground.
Possible failure modes:
1. Sensor signal wiring is open or shorted to ground.
2. Loss of power to the sensor.
3. Module internal failure (internal regulator failure).
Solution:
1. Enter the InfoView monitor - "Diagnose info" screen.
Select "Cleaning" sub menu.
Select "Lateral Inclination sens" and check voltage range.
The proper voltage range is 0.3 - 5.2 volts.
A. If the voltage reading is low (<0.3 volts) out of range, continue with Step 2.
B. If the voltage reading is within the proper limits, the circuit may not be open or shorted to ground at this
time. Continue the troubleshooting at step 5.
NOTE: Visually inspect the wiring harness and connectors. Verify that the connector was fully installed. Inspect
the terminals and wires at the connector for pushed back or corroded terminals or damaged wires. Flex the
harnesses involved to reveal intermittent breaks or shorts in the wiring concerned.
2. Key on. Disconnect connector X170, and use a multimeter to test for voltage on connector X170 pin A. There
should be 5 volts present.
A. If 5 volts is found, continue with step 3.
B. If no voltage is found, there is an open circuit in the main frame (MF) harness between connector X170
pin A and connector X019 pin J2-31 wire 451 pink or 453 pink. Locate the open and repair.
3. Key off. Disconnect connector X170. Use a multimeter to check for continuity between connector X170 pin C
and ground.
A. If no continuity is found, continue with step 4.
B. If continuity is found, there is a short to ground in the main frame (MF) harness between connector X170
pin C and connector X019 pin J2-33 wire 430 yellow. Locate the short and repair.
4. Key off. Carefully disconnect connector X019 from the bottom of the CCM1 module. Use a multimeter to check
for continuity between connector X170 pin C and connector X019 pin J2-33.
A. If continuity is found, the open is in the sensor. Replace the sensor.
B. If no continuity is found, there is an open circuit in the main frame (MF) harness between connector X170
pin C and connector X019 pin J2-33 wire 430 yellow. Locate the open and repair.
5. Operate the machine while monitoring InfoView monitor.
A. If no low out of range readings are indicated, erase the fault code and continue operation.
