It has the characteristic of being mirrored in relation to each other and they work with a speed
rate of 1,000 kbit / s, remembering that, as in the case of the CAN network, this protocol works with
the sending and receiving of data packets with a priority identifier. , indicating the urgency of the
signal, divide it into high traffic priority or low priority. Now see the electrical signal that this circuit
contains.

Mirrored signals give the J1939

Engine Speed Sensor Circuit

We noticed in this circuit as well as others the presence of resistors and diodes because the
characteristic signal of this system is analog and alternating, because of this present in this circuit
there is also an integrated circuit with its own functions of a digital analog converter.

Analog but rectified rotation

signal reaches pin 4 of this C.I,
and is converted to digital and
exits pin 26 of the same directly to
the processor

Important detail is that the same

C.I operates as a voltage regulator
supplying the passive sensors as
well as the entire logical part of the

No difference with respect to the EDC 07 system, observe the electrical signals.

Blue signal is the rotation input in

the circuit, note however that its
amplitude and its negative part
change (red signal), this change is
normal due to the existence of a
rectifier circuit. Right after
entering the integrated circuit
through pin 4, the rotation signal
goes through another
transformation (yellow signal),
that digital signal that comes goes
directly to the BGA encapsulation

BASIC ECU DIAGNOSTIC SCREENPLAY

To make an accurate diagnosis at the Centers as well as in any job, it is important to follow
some work routines and execute them to be successful. We will now observe some work routines
based on symptoms claimed by customers and what procedure is important to do in order to obtain
an eventual repair diagnosis of the ECU.

ECU DON'T WORK

1-Circuit Supply (in. Line +30, +15, +50 and grounding)

2- Voltage Regulator 5 volts

3-Power supply for logic part (processor, memories, C.I) 4-Broken track
5- Oxidized terminal
6- Rotation sensor circuit 7-Grounding
8- Cold weld
9- Corrupt injection file 10-Processor
11-Crystal

ECU DOES NOT PULSE INJECTORS OR OTHER ACTUATORS

1-Actuator trigger driver 2-Broken track

3-Filter capacitor 4-Oxidized terminal

5-Cold welding

SENSOR FAILURE
1-Broken trail

2-Filter capacitor

3-Sensor supply and mass

4-Circuit of the sensor in question (resistors and capacitors)
