The U0110 - Lost Communication With Drive Motor Control Module 'A' code indicates that the vehicle's Engine Control Module (ECM) or Hybrid Vehicle Control Module (HVCM) is unable to communicate with the Drive Motor Control Module 'A', which is critical in a hybrid system for controlling the electric drive motor.
Since you mentioned that the transmission was recently repaired and the vehicle is not starting, it's likely that something related to the communication or wiring between the control modules was affected during the repair.
Possible Causes:
-
Disconnected or Damaged Wiring/Connectors:
- The wiring harness or connectors to the drive motor control module may have been damaged or left disconnected during the transmission repair.
-
Faulty Drive Motor Control Module (A):
- The drive motor control module itself may have failed or is not receiving power.
-
Blown Fuse or Relay:
- A fuse or relay that supplies power to the drive motor control module may be blown or faulty.
-
Incorrect Installation or Grounding Issue:
- Improper installation of transmission-related components, including grounding points, could cause loss of communication.
Troubleshooting Steps:
-
Inspect Wiring and Connectors:
- Locate the Drive Motor Control Module 'A' (typically near the transmission or motor inverter).
- Check for loose, disconnected, or damaged wiring harnesses and connectors leading to the module.
- Ensure that all electrical connectors are securely plugged in and free of corrosion or debris.
-
Check Fuses and Relays:
- Inspect all fuses and relays related to the hybrid drive system and motor control. Replace any blown fuses.
- Ensure the module is receiving proper power and ground.
-
Inspect Grounds and Sensor Connections:
- Verify that all ground connections for the transmission and hybrid system are secure and properly connected.
- A missing or loose ground connection can cause communication issues between modules.
-
Check Transmission Sensors and Components:
- Ensure that all sensors related to the transmission (speed sensors, position sensors, etc.) are correctly installed and connected.
- Miscommunication from sensors can also cause the system to disable the hybrid drive.
-
Perform a Reset:
- Disconnect the 12V battery for 10-15 minutes to reset the system and clear temporary errors.
- Reconnect the battery, attempt to start the vehicle, and check if the code reappears.
-
Use a Toyota-Compatible Scanner:
- A Toyota Techstream or hybrid-compatible OBDII scanner may provide more detailed information about the problem.
- It can also help verify communication with other hybrid system modules and run diagnostic tests.
When to Seek Professional Help:
If the wiring, connectors, and fuses are intact but the code persists, you may need a hybrid technician to diagnose and potentially reprogram or replace the drive motor control module.
