A/T control system : fail-safe

TCM is equipped with an electrical fail-safe mode. The operation can be continued even if the signal circuit of the main electronically controlled input/output parts are damaged.

If the vehicle shows following behaviors including "poor acceleration", a malfunction of the applicable system is detected by TCM and the vehicle may be in a fail-safe mode. At this time, check the DTC code and perform inspection and repair according to the malfunction diagnosis procedures.
