U0110 Honda Code - F-CAN Malfunction Battery Condition Monitor Module-Motor Control Module
Quick Answer
The Controller Area Network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (CANH and CANL). Common causes include Faulty Motor Control Module (MCM) / Battery Condition Monitor (BCM), Motor Control Module (MCM) / Battery Condition Monitor (BCM) harness is open or shorted, Motor Control Module (MCM) / Battery Condition Monitor (BCM) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U0110 Honda Description
When the information is not sent from the Motor Control Module (MCM) through the F-CAN and this condition continues for a specified time or when the information sent from the MCM is abnormal and this condition continues for a specified cycle, the Battery Condition Monitor (BCM) module detects a malfunction and when BUS-OFF is not detected after the time to detect BUS-OFF has passed, a DTC is stored.
What are the Possible Causes of the DTC U0110 Honda?
- Faulty Motor Control Module (MCM) / Battery Condition Monitor (BCM)
- Motor Control Module (MCM) / Battery Condition Monitor (BCM) harness is open or shorted
- Motor Control Module (MCM) / Battery Condition Monitor (BCM) circuit poor electrical connection
How to Fix the DTC U0110 Honda?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
Do you have a vehicle with DTC U0110 (F-CAN malfunction [BCM module-MCM]) and DTC U1205 (IMA-CAN malfunction [BCM module-MCM]) set along with a blown No. 61 (10 A) IMA fuse in the auxiliary under-hood fuse/relay box? The culprit might be a bad IPU module fan.
To fix this problem, here's what you need to do:
- Replace the blown No. 61 (10 A) IMA fuse.
- Hook up the HDS and turn the ignition to ON.
- Do the IPU module fan drive test. In this test, the HDS changes the speed of the IMA module fan. It goes from off, to low (over 850 rpm), to middle (over 2, 200 rpm), to high (over 2,580 rpm).
--From the System Selection Menu, select IMA.
--From the Mode Menu, select Function Test.
--From the Function Test Menu, select IPU MODULE FAN DRIVE TEST. If the No. 61 fuse blows while this test is running, replace the IPU module fan, then clear the DTCs. If the fuse doesn't blow, see the DTC troubleshooting procedures in the electronic service manual.
What is the Cost to Diagnose the Code?
