PURPOSE
Affected vehicles may experience difficulties using a quick/fast/level 3 charging device or
switching to “Ready” mode after charging, along with DTCs P101B and P101C setting in the EV ECU
(in a stored state). In addition, DTCs P1B02 and/or P1B03 may possibly be set.
If these DTCs are in an active state, please proceed to diagnosis using the service manual.
This condition might be caused by one of the following operations:
D
The charge connector was removed while vehicle was quick charging.
D
The charging device powered off by activation of the circuit breaker or experienced a power
outage while quick charging.
D
The data communication between vehicle and quick charging device was interrupted by a
bump or strike to the charge connector.
This TSB provides instructions for reprogramming the EV-ECU with countermeasure software.
