DP: The Customer Confidence Program is a component of a class action settlement that includes several elements of coverage. The Customer Confidence Program provides coverage as it applies to the intelligent power module (IPM). The specific condition covered by this Customer Confidence Program 23TE02 is failure of the IPM located inside the inverter assembly of the hybrid system indicated by DTCs P0A7A and/or P0A78. If either of these DTCs are detected, various warning lamps on the instrument panel will also illuminate and the vehicle will enter Fail Safe Mode. Toyota will also provide coverage if the IPM has failed due to a thermal event regardless of what DTC is detected, or if the IPM has failed and the failure cannot be demonstrated to be due to anything other than a thermal event.
