M/T MODELS : Description
The vehicle speed signal is sent to the combination meter from the "ABS actuator and electric unit (control unit)" via the CAN communication line. The combination meter then sends a signal to the ECM via the CAN
communication line.
M/T MODELS : DTC Logic
DTC DETECTION LOGIC
NOTE:
-If DTC P0500 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
-If DTC P0500 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. P0607.
