2011 Toyota Prius – No Start and Stuck in Park With C2309

Aug 15

1 min read

CUSTOMER CONCERN

Customer states the vehicle will not start, will not shift out of Park and cannot be switched off normally after the discharged 12-volt battery was replaced. DTC C2309 is stored.

CAUSE

Confirmed failed IGCT relay interrupted B+ power through the IGCT No. 2 and No. 3 fuse circuits to the transmission control ECU. The Blue wire at terminal 16 of connector A should receive battery voltage with the power switch on; C2309 sets when ECU B+ remains at 3 volts or less for at least one second.

CORRECTION

Remove and replace the IGCT relay.
