WARNING: This page is about a different variant/trim than selected.

When attempting to set DTCs, it may be helpful to ensure the TCM is warmed up and the transmission is operated in second gear long enough to ensure a 3°C (5°F) increase in TCM temperature. This will place the TCM under the optimal conditions to test DTCs.
