E0196-11 - Grid Heater output Unidentified Failure Code
NOTE: This troubleshooting chart is for CX 860 and CX 880 combines with Iveco engines Series 1348 and above.
Cause:
The grid heater output circuit is open, or shorted to ground.
Possible failure modes:
1. Supply wiring damaged.
2. Bad cold start indicator E-36.
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 6.
2. Key switch off. Disconnect connector X066 from the cold start indicator E-36 . Use a multimeter to check for
continuity between connector X066 pin 9 and chassis ground.
A. If there is continuity to ground, continue with step 3.
B. 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 the open and repair.
3. Use a multimeter to check for continuity between connector X066 pin 7 and chassis ground.
A. If there is continuity to ground, there is a short to ground in the cab main (CM) harness between connector
X066 pin 7 and X015 pin J1-12 wire 839 white. Locate the short and repair.
B. If there is no continuity to ground, continue with step 4.
4. Turn the key switch to the ON position. Use the InfoView monitor - "Diagnose info" screen to manually power
the grid heater circuit. Use the multimeter to check for 12 volts at connector X066 pin 7.
A. If there is no voltage, there is an oprn circuit in the cab main (CM) harness between connector X066 pin 7
and X015 pin J1-12 wire 839 white. Locate the open and repair.
B. If there is voltage, the circuit is operating properly. Replace the cold start indicator E-36.
