GAC JDR Series Quick Start Manual

1 OVERVIEW
The JDR Series is a J1939 diagnostic code reader designed to display the
numeric value or the text translation of a trouble code being reported by
an engine's electronic control unit (ECU). The unit can read both active
and stored codes. The TSC1 model also provides speed control capabil-
ities.
These proven units offer simple access to live events for real time reac-
tion. Easy to install, the units display both active and stored codes. The
base model supports Diagnostic Trouble Codes (DTCs) and 6 live engine
parameters.
The TSC1 model adds the ability to increase and decreases engine speed
in pre-determined increments to alter speed for a predetermined period of
time.
The IV models add a regeneration cycle option that can be preset or
completed manually allowing the user to support Tier IV Diesel Particu-
late Filter (DPF) operations.
There are 5 JDR models:
The JDR050 is a 4-mode basic unit with 2 buttons that display 6 dig-
DTC codes and 4 alpha numeric characters such as DTC field identifier
(DTC, FMI, OC, SRC), or, in text mode, the description of the field.
JDR100 builds on the JDR050, displaying 6 live engine parameters by default: RPM,
Oil Pressure, Coolant Temperature, Fuel Level, Battery Voltage, Engine Run Hours, as
well as J1939 stop, warning, malfunction, and protection status messages.
The JDR100-TSC1 includes all the JDR100 abilities and adds the ability to control engine
speed from the unit with J1939 TSC1, Torque Speed Control. With a push of a button you
can increase or decrease engine speed in preset increments that produce a ramp-like
response and immediate speed update.
JDR050-IV and JDR100-IV add Tier IV Diesel Particulate Filter (DPF) operations include
their base unit capabilities and the added Tier-IV support. The DPF regeneration cycle can be enabled or disabled or manually
forced directly from the -IV unit.
