YAW RATE/”G” SENSOR INSPECTION AND HECU UPDATE
(RECALL CAMPAIGN 137)
This bulletin supersedes TSB 16-01-011 to include information regarding additional ROM IDs.
 IMPORTANT
*** Retail Vehicles ***
Dealers must perform this Recall Campaign whenever an affected vehicle is in the shop for any
maintenance or repair.
When a vehicle arrives at the service department, access Hyundai Motor America’s “Warranty
Vehicle Information” screen via WEBDCS to identify open Campaigns.
Description:
On certain 2011 to 2012 model year Elantras (MD/UD), the Yaw Rate/”G” sensor may send a signal
that may result in one or more of the following:
1. Inadvertent ESC system intervention,
2. Illumination of the “ESC” indicator lamp in the instrument cluster.
3. Diagnostic codes C1282 and/or C1283 (for the yaw sensor) stored in the ESC Control Module.
ESC system intervention may include inadvertent brake application to one or more wheels and/or
reduced engine torque, both of which can increase the risk of a crash. This bulletin describes the
procedure to check for diagnostic codes, replace the Yaw/”G” sensor if necessary, and update the
hydraulic unit ECU (HECU) software.
Applicable Vehicles: Certain 2011 ~ 2012 Elantras (MD/UD)
