原廠摘要

以下為英文原文

DESCRIPTION Some CX-70 and CX-90 PHEV vehicles may fail to start (enter READY mode) in cold weather, but the vehicle can often be started successfully on the next attempt. This may occur when leakage current between connector terminals causes the MAIN Relay to be falsely detected as ON. As a result, the Battery ECU may incorrectly determine the relay status, preventing READY mode activation and resulting in a no-start condition. One or more of the following DTCs may be stored: P0AB9, U0100, U0110, and U0115 and multiple warning lights may also turn on. This is caused by corrosion of the connector terminals on the 3002-411 connector in the luggage compartment from water. To eliminate this concern, urethane has been added around the connector to help prevent water from reaching the connector terminals. REPAIR PROCEDURE 1. Verify the customer concern. 2. Diagnose and repair the vehicle according to the following steps. NOTE: The following procedure uses a heat shrink tube with solder. (1) Connect wire to wire with heat shrink tube. (2) Form a loop at the end of wire to create a passage for the other wire.
