DESCRIPTION
This circuit is the power source circuit for the meter. This circuit provides two types of power sources; one is a constant power source mainly used as a backup power source, and the other is an IG power source mainly used for signal transmission. The constant power source is mainly used as a backup power source for the meter CPU, however, it is also used for CAN communication. If a voltage of 12 V is not applied to terminal IG+ when the ignition switch is turned to ON, the indicators will not operate.

DESCRIPTION
The ECM uses signals from the output shaft speed sensor and input speed sensor
to detect the actual gear position (1st, 2nd, 3rd, 4th or 5th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory
to detect mech ...
