A/T INDICATOR
A/T INDICATOR
System DescriptionINFOID:0000000005395032
The TCM receives A/T indicator signals from the transmission range switch (R-range, D-range, 2-range and 1-
range) and the combination meter (P-range and N-range). The TCM then sends A/T position indicator signals
to the combination meter via CAN communication lines. The combination meter indicates the received shift
position.
