during Scanner diagnosis and critical programming process.
process (12V systems)
Diagnosis / Programming
diagnosis starts with ignition key ON , the voltage shown always be above 12.0V.
engine OFF, during diagnosis with Scanners the voltage should always be more
code programming e.g. key programming, some European cars may need over 13.0V or
14.0V (depending on the Car Manufacturer requirement). In this case, you may
need to connect an external 12V power supply to the battery to boost up the
voltage if it is below this limit.
shows that the latest car model, the voltage requirement for this process
will be higher.
the engine is running, DO NOT connects the external 12V power supply to the
battery which may damage this power supply unit.
NOT confuse and mix up the application of an external 12V power supply with
the 12V battery charger as their functions differ individually.
the engine is SLOW, the voltage should above 12.8V during load. Anything below
this voltage limit indicates that the Alternator has aged or needs to be fixed.
acceleration, the charging voltage should above 14.0V but not exceeding 15.0V.
Night driving with the Headlights, Air condition and Cooling Fans ON it is
normal that the voltage is slightly below this limit.
This cable can be used
on passenger cars (12V) type-A and type-B trucks (24V) OBD2 connector.
