Manufacturer summary

Original wording in English

TSB: Some 2001 ? 2002 model year Sequoia vehicles may exhibit intermittent VSC activation. After the activation, Diagnostic Trouble Code (DTC) C1234 is stored in the skid control Electronic Control Unit (ECU) memory. Follow the Repair Procedure in this bulletin to address this condition. NOTE ? This Service Bulletin is ONLY applicable if DTC C1234 is present. If DTC C1234 is NOT present, this Service Bulletin is NOT applicable. ? The yaw rate sensor is available as a separate service part allowing it to be replaced separately instead of the entire yaw rate sensor assembly (Yaw Rate Sensor, Decel Sensor & Bracket). Ensure that the NEW service part number is ordered for the yaw rate sensor.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
