Shivering Scion

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.

PREVIOUS IG1 RELAY                                    NEW IG1 RELAY

90987-02025 (gray)                                        90987-02031

90987-02030 (pink)                                        90987-02031

NOTE: The TIS Techstream with software version 4.12.001 or later is required.

  1. Locate the instrument panel junction block No. 1 in the instrument panel.
  2. Remove and verify the part number of the IG1 relay. If the part number is NOT 90987-02031, replace the relay with the new P/N IG1 relay 90987-02031. 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.
  3. Connect TIS Techstream and clear any stored DTCs.
    Note the location of the IG1 relay.
