Serial Data
On vehicles equipped with an automatic transaxle the
powertrain control module (PCM) will have an internal
serial data line. This line will allow the engine controller
(EC) to send and receive signals from the transaxle controller
(TC) and ABS. The EC will control this serial data line within the PCM.
NOTE: The TC and EC are both located within the
PCM.
