Fix Multiple electrical problems Toyota vehicles

Toyota has issued a TSB #T-SB-0047-09 to fix multiple unrelated electrical issues in the following vehicles: 2006-09 Corolla, Highlander, Matrix, Prius, RAV4, and Sienna. The symptoms are multiple warning lights on, vehicle will not shift from park to drive, and other accessories inoperative. The symptoms usually happen when outdoor temperatures are below 14 degrees F. To fix the problem, replace the IG1 relay. This relay is located in the instrument panel junction block.

Look for the relay in the lower left hand corner. The old relay number is 90987-02025 or 90987-02030. Replace either of those relays with the new part #90987-02031.
