check its operation, use the sensors test module in the
Frequency function. Using the PU02 cable set, connect
the green tip to the "IN" input and the red tip to the "+
5V REF" input, then connect the green alligator clip to the
DFM, FR or LI terminal attached with the red alligator clip
(+ 5V REF). Perform the regulator test and, during the test,
EN
the DFM (FR, LI) signal output frequency and the percen-
tage of the time that the signal remains high should appear
on the LCD screen of the sensors test module.
Regulators with "P", "W" terminal - regulator pulse
output terminal generally used for the vehicle's tachome-
ter. To check its operation, use the sensors test module in
the Frequency function. Using the PU02 cable set, con-
nect the green tip to the "IN" input, and then connect the
green alligator clip to the "P" or "W" terminal. During the
test, the LCD display will show the output frequency to the
tachometer.
Regulators with "D", "PWM" terminal - this regu-
lator terminal is used by the vehicle's Electronic Control
Unit to control the voltage set point. The Tester is supplied
with a PD/PWM DRIVER that allows for testing this type
of regulator by simulating the signal sent by the Electronic
Control Unit to the regulator. To perform the test, follow the
procedure below:
• Connect the green cable of the DRIVER to the
cable of the regulator testing harness (RM01) and the bla-
ck cable of the DRIVER to the black cable of the harness
• Connect the white cable of the DRIVER to the "D" or
"PWM" terminal of the regulator
• If the regulator is a "PD" type, connect the blue cable of
the DRIVER to the "P" terminal of the regulator
• Connect the regulator testing harness (RM01) as indica-
ted on the instructions and perform the test

3.3.1 Use of PD/PWM Driver

The "PD/PWM" DRIVER is a device for testing re-
gulators controlled by the vehicle's Electronic Control Unit.
To start the test using this device, select the con-
trol method corresponding to the regulator via the PD/
PWM switch. Connect the green and black cables to the
respective cables on the regulator testing harness (RM01).
Connect the white cable to the input pin and, when ne-
cessary, the blue cable to the output pin of the regulator,
corresponding to communication with the vehicle's control
unit.
NOTE: Some regulators have different connections and
the identification of pins is available for each model indi-
vidually.
Switch "V1" and "V2" may be used to vary the
input signal to check whether the regulator is responding
to the selected control method.
The GREEN
tput (simulating the electronic control unit) to the regulator
30
LED indicates the driver signal ou-
and the yellow LED indicates the regulator communication
signal output to the electronic control unit.
To perform operating diagnostics on the PD/PWM
Driver:
Test the "PWM" signal: Connect the green and bla-
ck cables to the respective cables on the regulator testing
harness (RM01). Activate the regulator testing module.
Connect the white wire to the blue wire of the driver. The
yellow LED should flash, indicating proper communication.
The green LED stays on.
Test the "PD" signal: Press the TYPE A button
GREEN on the regulator testing module. Connect the green and
black cables to the respective cables on the regulator
testing harness (RM01). Still on the regulator testing har-
ness, connect the black cable to the yellow cable. Hold
the "TEST" button down and observe the green LED that
should go out while the voltage increases, indicating pro-
per functioning of the "PD" signal.

3.4 Ignition Module Testing

First, find the technical information for the model
to be tested on the website www.gauss.com.br/bt010:
• Press the "POWER SUPPLY/RESET" button to activate
the equipment's power supply
• Connect the testing harness (RM02) as indicated for the
model, abiding by the colors corresponding to each modu-
le function
• Select the type of input signal corresponding to the mo-
dule being tested. Note: the type of input signal is indicated
in the module instructions on the website. The Tester has
four types of input signals: Signal 1 (Pick-up) is the signal
for modules controlled by magnetic effect. Signal 2 (Hall)
is the signal sent by the electronic control unit to control
the ignition module. Signal 3 (Renault) is used in some
Renault ignition modules and signal 4 (Delco) is used in
some Chevrolet ignition modules
• Press the "MODULE/COIL" button to activate this testing
module. A high-voltage spark should appear in the spark
gap. To test the module at different speeds, press the
"SPEED" button up to increase the module tripping speed
and down to reduce speed. At the top of the "SPEED" but-
ton is a blinking yellow LED, indicating the trip output. If
there is no high-voltage spark in the spark gap, the module
is defective
