Other Parts Discussed in Thread: TPIC7218
Tool/software:
Please help analyze:
Due to an occasional failure during the test, the wheel speed sensor was reported to be overcurrent faulty, and the function could not be restored by re-enablement.
Therefore, do the simulation test as follows:
Short circuit wheel speed sensor for a short time, then restore the circuit.
The system reports an overcurrent fault
If the following software is re-enabled, the function cannot be restored
Test the input pin of the wheel speed sensor signal with a multimeter and the voltage is 10V.
It is preliminarily presumed that the WSLS was shut down after an overcurrent failure.
We would like to ask, how can this situation be recovered?
In addition, the attached table: the resistor configuration of our current TPIC7218, please help to see if it is reasonable。
