TSB Document:
Affected Component: ELECTRONIC STABILITY CONTROL:AUTOMATIC (ASC)
- Summary
- 50210 - Service Update (revised population - message only). These vehicles may have a condition where the EBCM does not notify the driver through an ABS or Electronic Stability Control (ESC) telltale or set the appropriate diagnostic trouble codes (DTC) if an open flyback diode condition, or a shorted dump transistor condition, is detected. ABS isolation functionality is disabled by the EBCM on affected wheel(s), and a shorted dump transistor will disable dump control, without notification to the driver. Dealers will reprogram the electronic brake control module (EBCM).
