E0196-11 - Grid Heater output Unidentified Failure Code
NOTE: This troubleshooting chart is for CX 860 and CX 880 combines with Iveco engines Series 1206 - 1347 only.
Cause:
The grid heater output circuit is open, or shorted to ground.
Possible failure modes:
1. Supply wiring damaged.
2. Bad cold start indicator.
3. Controller internal failure (internal regulator failure).
Solution:
1. Enter the InfoView monitor - "Diagnose info" screen.
Select "Engine" sub menu.
Select "Grid Heater output" 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 14.
2. Remove the ignition switch panel in the cab, and unplug connector X066 from the cold start indicator E36 . Use
a multimeter to check for continuity between connector X066 pin 9 and chassis ground.
A. If there is no continuity to ground, there is an open circuit in the cab main (CM) harness between connector
X066 and cab ground 3 wire 294 black. Locate open and repair.
B. If there is continuity to ground, continue with step 3.
3. Use a multimeter to check for continuity between connector X066 pin 7 and chassis ground.
A. If there is continuity to ground, continue with step 4.
B. If there is no continuity to ground, continue with step 8.
4. Disconnect connector X004 . Use a multimeter to check for continuity between connector X004 pin 20 and
chassis ground.
A. If there is no continuity to ground, a short to ground is located in the cab main (CM) harness between
connector X066 and connector X004 wire 814 white. Locate short and repair.
B. If there is continuity to ground, continue with step 5.
5. Disconnect connector X010 . Use a multimeter to check for continuity between connector X010 pin 7 (main
frame (MF) harness side) and chassis ground.
A. If there is continuity to ground, a short to ground is located in the main frame (MF) harness between
connector X004 and connector X010 wire 814 white. Locate short and repair.
B. If there is no continuity to ground, continue with step 6.
6. Use a multimeter to check for continuity between connector X010 pin 7 (engine (EN) harness side) and chassis
ground.
A. If there is continuity to ground, a short to ground is located in the engine (EN) harness between connector
X010 pins 7 and 20 wire 814 white. Locate short and repair.
