E0182-11 - Fuel Shutoff / Terminal 15 Unidentified Failure Code
NOTE: This troubleshooting chart is for CX 720, CX 740, CX 760, CX 780 and CX 820 combines with 7.5 L mechanical
governor engines only. The troubleshooting chart for this fault code on CX 840, CX 860 and CX 880 combines with
electronic governor engines follows this chart.
Cause:
The fuel solenoid (L-02) circuit open, or shorted to ground.
Possible failure modes:
1. Supply wiring damaged.
2. Bad solenoid.
3. Controller internal failure (internal regulator failure).
Solution:
1. Enter the Infoview monitor - "Diagnose info" screen.
Select "Engine" sub menu.
Select "Fuel Shutoff / Terminal 15" and select the "Status" screen. Press the "Enter" key to manually power the
circuit.
The status screen should indicate "OK" If the circuit is working properly.
A. If the status screen indicates "Error", the circuit is open or shorted to ground. Continue with Step 2.
B. If the status screen indicates "OK", the circuit is working properly. Continue with step 9.
2. Disconnect connector X290. Use a multimeter to check between connector X290 pin A (valve side) and chassis
ground.
A. If there is continuity, the fuel solenoid is shorted to ground. Replace the solenoid.
B. If there is no continuity, continue with step 3.
3. Use a multimeter to check for continuity between connector X290 pin A (harness side) and chassis ground.
Flex the engine (EN) harness between the fuel solenoid and connector X010 while making this check.
A. If there is continuity to ground, continue with step 4.
B. If there is no continuity to ground, continue with step 5.
4. Disconnect connector X010. Use a multimeter to check for continuity between connector X010 pin 16 and
chassis ground. Flex the main frame (MF) harness between the connector X010 and connector X016 while
making this check.
A. If there is no continuity to ground, the short to ground is in the engine (EN) harness between connector
X010 and connector X290 wire 571 white. Locate the short and repair.
B. If there is continuity to ground, the short to ground is in the main frame (MF) harness between connector
X010 and connector X016 wire 571 white. Locate the short and repair.
5. Disconnect connector X290. Use a multimeter to check the resistance of the fuel solenoid coil between connec-
tor X290 pins A & B. The proper resistance range is XX to XX ohms.
A. If there is no continuity, replace solenoid.
B. If the coil is within specification, continue with step 6.
