Our AL619 can trip the check engine light on? I don't know it has this function. ... Well, U0155 = lost communication with IPC control module.....U110C is a chrysler code. NO FUEL LEVEL BUS MESSAGE. When Monitored and Set Condition:
U110C-NO FUEL LEVEL BUS MESSAGE
When Monitored: Ignition on.
Set Condition: No fuel level BUS messages received by the PCM for 20 seconds.
POSSIBLE CAUSES
DTC RESET
COMMUNICATE WITH BCM
FUEL LEVEL BUS MESSAGE
PCI BUS CIRCUIT OPEN FROM PCM TO BCM

TEST ACTION APPLICABILITY
1 NOTE: If a fuel level circuit or performance DTC is set along with P1681,
diagnose the circuit/performance DTC before continuing.
Turn the ignition on.
With the DRBIIIt, erase DTCs.
Start the engine on and off several times. Leave the engine running for at least 20
second each time.
With the DRBIIIt, read DTCs.
Does the DTC reset?
All
Yes ! Go To 2
No ! Refer to the INTERMITTENT CONDITION symptom in the
Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.
2 Ignition on, engine not running.
With the DRBIIIt, attempt to communicate with the BCM.
Can communication be established with the BCM?
All
Yes ! Go To 3
No ! Refer to the Communication Category and perform the appropriate
symptom related to no communication with BCM.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.
3 Turn the ignition on.
Using the DRBIIIt, read the Fuel Level parameter in the PCM.
Does the DRBIIIt display a fuel level value?
All
Yes ! Replace and program the Powertrain Control Module in accordance
with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.
No ! Go To 4

TEST ACTION APPLICABILITY
4 Turn the ignition off.
Disconnect the PCM harness connectors.
Disconnect the BCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS
RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the PCI Bus circuit from the BCM harness connector to the
appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes ! Replace BCM in accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1 - NGC.
No ! Repair the PCI Bus circuit between the PCM and the BCM for an
open.
