1.2 FUNCTIONS
FUNCTION 1: DETERMINE FAULT
1. Read, clear fault codes stored in ECUs of engine system and ABS
system
2. Find complex faults that MIL lamp does not indicate such as:
- Diagnose faults by the automatic data analyzing and interviewing the
technicians
+ Can’t start engine
+ Down power when accelerate
+ Idling stop fault
+ Fuel consumption
+ Starter is not work
+ Random acceleration
+ Constant acceleration
+ Idling not work
+ Hard to start engine
+ Weak engine
+ Injector mechanical fault
- Diagnose faults by analyzing the engine live data and activate the
actuators
+ Voltage and open angle of throttle position sensor (TPS)
+ Voltage and value of intake air temperature sensor (IAT)
+ Voltage and value of manifold air pressure sensor (MAP)

Activate and reset the actuators:
Fuel pump, injector, ignition coil,
IACV (ISCV), O2 heater, pump, blower, head lamp, MIL warning lamp, ABS
warning lamp, Immobilizer lamp, Start&Stop lamp, engine oil pressure
warning lamp, VVA valve, reset pre-positioning of crankshaft ...
FUNCTION 2: REPAIR FAULT
1. Automatically program smart key for HONDA, YAMAHA, SUZUKI:
- Read all KEYID# and ECMID from vehicle SCU
- Program smart key directly with vehicle or without vehicle (SCU is not
installed on vehicle) for cases:
+ Register more FOB# for all of cases
+ Register FOB# when lost all of the FOB#
+ Delete KEYID in SCU memory
