E0315-11 - Rotor RTF Clutch Valve - Unidentified failure
Control Module : CM3
Cause:
The rotor RTF clutch valve (L-46) circuit open or is shorted to ground.
Possible failure modes:
Supply wiring shorted to ground or open circuit.
Controller internal failure.
Solution:
Using the Display Monitor diagnostics capability to view "Parameter" status, reference Instrument cluster - Detailed view, if needed, change the circuit output to "ON".
If the status screen indicates "ERROR", the circuit is open or shorted to ground. Continue with Step 2.
If the status screen indicates "OK", the circuit is working properly. Continue with Step 9.
Turn the key switch to the OFF position and disconnect the rotor RTF clutch connector X409. Use a multimeter to check the resistance of the rotor RTF clutch solenoid. The proper resistance range for the coil is 1.0 - 8.0 ohms.
If out of specification, replace coil.
If the coil is within specification, continue with Step 3.
Use a multimeter to check for continuity between the gearbox (GB) harness end of connector X409 pin 1 and chassis ground. Flex the gearbox (GB) harness while making this check.
If no continuity to ground is found, continue with Step 4.
If there is continuity to ground, continue with Step 7.
Turn the key switch to the ON position. Using the Display Monitor, reference Instrument cluster - Detailed view, if needed, manually power the rotor RTF clutch solenoid. Use a multimeter to check for 12 volts between connector X409 pin 1 and chassis ground.
If 12 volts is not present, continue with Step 5.
If 12 volts is found, continue with Step 9.
Key switch to the ON position. Using the Display Monitor, reference Instrument cluster - Detailed view, if needed, manually power the rotor RTF clutch solenoid. Use a multimeter to check for 12 volts between connector X011 pin 27 and chassis ground.
If 12 volts is not present, continue with step 6.
If 12 volts is read, there is an open circuit in the gearbox (GB) harness between connector X011 and connector X409 wire 1049 white. Locate the open and repair.
Key switch to the ON position. Using the Display Monitor, reference Instrument cluster - Detailed view, if needed, manually power the rotor RTF clutch solenoid. Use a multimeter to check for 12 volts between connector X219 pin 9 and chassis ground.
If 12 volts is not present, there is an open circuit in the expansion (EX) harness between connector X219 and connector X014 J3-3 wire 1049 white. Locate the open and repair.
If 12 volts is read, there is an open circuit in the main frame (MF) harness between connector X219 and connector X011 wire 1049 white. Locate the open and repair.
Disconnect connector X011. Use the multimeter to check for continuity between connector X011 pin 27 and chassis ground.
If continuity is found, continue with step 8.
If no continuity is found, the short to ground is in the gearbox (GB) harness between connector X011 and connector X409 wire 1049 white. Locate the short and repair.
Disconnect connector X219. Use the multimeter to check for continuity between connector X219 pin 9 and chassis ground.
If continuity is found, the short to ground is in the expansion (EX) harness between connector X219 and connector X014 J3-3 wire 1049 white. Locate the short and repair.
If no continuity is found, the short to ground is in the main frame (MF) harness between connector X219 and connector X011 wire 1049 white. Locate the short and repair.
Visually inspect the harness and connectors for damage, bent or dislocated pins, corroded terminals or broken wires.
If no damage is found, erase the fault code and continue operation.
