A/T INDICATOR
A/T INDICATOR
System DescriptionINFOID:0000000001704515
The TCM receives A/T indicator signals from the park/neutral position (PNP) 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 indi-
cator signals to the combination meter via CAN communication lines. The combination meter indicates the
received shift position.
