Some 2005-2009 tC and 2008-2009 xD and xB Scion vehicles may exhibit a condition with multiple warning lights illuminated, the transmission not shifting from Park to Drive, and/or other accessories becoming inoperative after the vehicle has cold-soaked in sub-freezing ambient air temperature (below 14 degrees Fahrenheit).
A newly designed IG1 relay has been made available to address this concern.

- Locate the instrument panel junction block No. 1 in the instrument panel.

If the existing IG1 relay does feature the new part number 90987-02031, diagnose the specific conditions reported by the customer or based on MIL “ON” codes that are stored.
- Connect TIS Techstream and clear any stored DTCs.
