DTC
C1370/73 Engine or Transmission System Matching Error
DESCRIPTION
This DTC is set by the skid control ECU when the ECM is replaced with one that has different engine and
transmission information than the information stored in the skid control ECU.
This DTC is also set when the VSC actuator assembly (skid control ECU) is replaced with one that has different
engine and transmission information than the information stored in the ECM.
The ECM determines the transmission information according to whether or not there is a connection at a certain
ECM terminal and sends its stored engine and transmission information.
