TCM
Fail-safe
INFOID:0000000009464219
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically contro lled input/output parts is 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-sa fe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.
