10-
number through the change of pulse frequency.
13、The speed signal comes from the K-signal of ECU;
14、Gear signal, gear signal from gear controller voltage signal (L, h, N, R, P)
15、Engine fault indicator lamp, after engine operation fault alarm indicator
lamp extinguished, engine operation this indicator lamp is still on, engine
operation may not be normal, can use the old, fault diagnostic instrument to
detect the fault code of the engine, fault code refers to the self-diagnosis
system detected fault or fault.
▇ open the hood upper cover and look for the harness connector
of the fault diagnosis tester next to the ECU.
▇ Unplug the protector and connect the fault
diagnosis tester with special data line.
Open the fault diagnosis tester and read the fault code.
