TIS 18 provides a 14-step diagnostic flow for the EPS control module, including checking the CAN bus resistance between pins 6 and 14 of the DLC (Data Link Connector) – something no generic manual includes.
For the 2011–2012 model years, Chevrolet made significant gains in European J.D. Power customer satisfaction surveys, particularly in Germany and the UK. Independent analyses attributed part of this improvement to reduced “service repeat visits”—a direct metric of diagnostic accuracy. The TIS enabled technicians to correctly address software glitches (common in the early Cruze’s transmission control module) and intermittent electrical faults (notorious in the Captiva’s body control module). TIS 18 provides a 14-step diagnostic flow for
Nevertheless, the system could not overcome structural issues. Many independent garages, reluctant to pay the annual TIS subscription fee (often €1,500–€3,000), chose to refuse Chevrolet vehicles—undermining Chevrolet’s goal of mass-market acceptance. By late 2012, GM began merging European TIS into the global GM Global Diagnostic System (GDS 2), signaling that the standalone Chevrolet Europe TIS was a transitional solution. For the 2011–2012 model years, Chevrolet made significant
