E0033-03 - Lateral Inclination Sens Shorted To High Source
NOTE: This troubleshooting chart is for CX combines Series 1206 - 1237 only.
Cause:
The lateral inclination sensor (B02) 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 - "Diagnose info" screen.
Select "Cleaning" sub menu.
Select "Lateral Inclination sens" and check voltage range.
The proper voltage range for the lateral inclination sensor is 0.3 - 5.2 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 lateral inclination sensor connector X170.
A. If the voltage drops back to 0.3 - 5.2 volts the short is in the sensor, or sensor wiring. Replace the sensor.
B. If the voltage remains high on InfoView display then the short circuit is somewhere between connector
X170 on the main frame harness and connector X019 J2-33 on CCM1 wire 430 yellow.
3. Visually inspect harness and connectors for damage, bent or dislocated pins, corroded terminals or broken
wires.
A. If no damage is found erase fault code and continue operation.
