* Description of Type
S Type A : TCM will request the illumination of MIL and store DTC when TCM detects a failure on the first ignition
cycle.
S Type B : TCM will request the illumination of MIL and store DTC when TCM detects failures on two consecutive
ignition cycle.
S Type D : TCM will not request the illumination of MIL or hold lamp, but will store DTC when TCM detects a failure
on the first ignition cycle.
