how to resolve U0101 code on my Honda Pilot YF3 (2016-2022)

Solution

1. Preparation

• Gather the necessary tools and parts.
• Disconnect the vehicle battery to ensure safety during repairs.

Tools Required:

• OBD-II scanner
• Multimeter
• Socket set
• Torque wrench
• Wire stripper/crimper

2. Inspect and Clean Connectors

• Remove the TCM connector from the TCM.
• Inspect the connector pins for corrosion or damage.
• Clean the connectors with electrical contact cleaner.
• Reconnect the TCM connector securely.

3. Repair or Replace Wiring

• Inspect the wiring harness between the TCM and ECU carefully.
• If damaged wiring is found, repair it by stripping the insulation and using heat-shrink tubing to cover the repair.
• If the wiring is extensively damaged, consider replacing the entire harness.

4. Test TCM Power and Ground

• Using a multimeter, check for proper voltage at the TCM power and ground terminals.
• If voltage is low or absent, trace the circuit back to the ECU and repair any broken connections.

5. Replace TCM (if necessary)

• If all wiring and connections are intact, and the issue persists, the TCM may need to be replaced.
• Remove the TCM using the socket set.
• Install the new TCM, ensuring that all connectors are secure.
