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 memory. Follow the Repair Procedure in bulletin T-SB-0012-18 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.

New Part Number 89183-0C010
