Re: One problem fixed, a lot? more appear... U110A, U0114 & U1411
You obviously have more than one problem here. All those codes are communications related....lost or implausible. Do all the easy, low/no cost stuff first. Like robpp said, check the battery....do a load (discharge) and a capacitance test, if possible. Could also be an ignition switch. Check all wiring connections (plugs) to the PCM/TCM, and at the Control Modules. Pull and reset all fuses/relays within the modules. Clear the codes. Carefully drive it again. If that doesn't do it, here's a bunch of stuff from another DCX forum. This doesn't addresss the brake problem though. Are there any brake related codes showing?
"U110A is lost communication with SCCM- CAN C. Check the SCCM connector first and make sure the connector terminals aren't pushing out or spreading open. To do this, you have to remove the steering wheel and then the SCM (The part of the column that contains the SCCM, multi-function switch, the cruise switch, the clockspring, and the SAS). Make sure the clip that locks the connector to the column bracket is present. There is a replacement connector available. Otherwise, the SCCM may be the culprit."
U110A-LOST COMMUNICATION WITH SCCM - CAN C
For a complete wiring diagram Refer to Section 8W
- With the ignition on
- Battery voltage between 10 and 16 volts
- IOD fuse installed
- FCM is configured correctly
- Set Condition: Bus messages not received from the SCM (CAN C) for approximately 200ms.
-CAN B BUS CIRCUITS OPEN OR SHORTED
-DTCS RELATED TO BATTERY VOLTAGE, IGNITION, OR VIN MESSAGES
-FCM NOT CONFIGURED CORRECTLY
-STEERING CONTROL MODULE
-STEERING CONTROL MODULE POWER AND GROUND
-MODULE THAT SET THIS DTC
1. VERIFY DTC IS ACTIVE
NOTE: Ensure the IOD fuse is installed and battery voltage is between 10 and 16 volts before proceeding.
With the scan tool, read active DTCs.
Is this DTC active?
Yes No 2. CHECK FOR ANY OF THE FOLLOWING ACTIVE DTCS
With the scan tool, read active DTCs from all modules.
NOTE: Check for FCM configuration, CAN B or C hardware electrical, VIN Missing/Mismatch, battery or ignition related DTCs.
Does the scan tool display any active DTCs to the conditions listed above?
Yes No 3. VERIFY THAT THE SCM IS ACTIVE ON THE BUS
Turn the ignition on.
With the scan tool, select ECU View.
Verify that the SCM is active on the bus.
Is the SCM active on the bus?
Yes No 4. CHECK FOR ADDITIONAL COMMUNICATION RELATED DTCS
With the scan tool, select Network View and select Advanced.
Is there more than one module with active DTCs “Logged Against” the SCM?
Keep us posted on your findings.
