FOR MODELS WITH FLASH REPROGRAMMING
NOTE: Do not attempt to Flash Reprogram a vehicle that has a discharged or defective battery. Make sure
that the vehicle battery is in good condition and FULLY CHARGED before proceeding.
The charger is designed to supply up to 100A in "Flash Reprogram" mode.
Some newer vehicles may require more than 100A while flash reprogramming the ECU. Consult the vehicle
manufacturer's specifications to determine the required amperage. The charger's "Flash Reprogram"
mode cannot be used on vehicles that require more than 100A, or damage to the ECU and/or vehicle's
electrical system may occur. Failure to follow these instructions may also damage the service center's flash
reprogram equipment.
1. Set the mode to Flash.
2. Use Up and Down buttons to adjust the voltage needed for the vehicle being programmed (refer to
OEM specifications). Voltage selected is shown on the digital display. The unit has a voltage range
of 13.0 to 15.0, with a default of 14.2.
NOTE: When the Volts LED stops blinking, the display shows the selected voltage.
3. Press START/STOP to activate the output.
NOTE: During this time, the other buttons will not work until you turn off the output. When the display shows
OFF, no buttons will work for five seconds; then it automatically goes back to the default state.
4. When finished with Flash Reprogramming, press START/STOP to exit this mode.
NOTE: The clamps are live during Flash Reprogramming.
BATTERY PERCENTAGE
Press the Display Mode button to switch from battery voltage to current or battery percentage.
FOR MODELS WITH A MEMORY SAVER
Use a memory saver to save the vehicle's on-board diagnostic computer settings (radio programs,
diagnostic codes, etc.) while the battery is disconnected from the vehicle during repair or maintenance.
NOTE: The 12V port is rated at 15A; the provided OBDII cable has an 8A fuse.
IMPORTANT: Some vehicle manufacturers do not allow the use of a memory saver through the OBDII. Consult
the vehicle manufacturer before use, to determine if a memory saver is acceptable for use on the vehicle.
1. Make sure that Charge/Boost/Engine Start are off. Do not operate or crank when using a memory
saver. Do not charge a battery when operating the memory saver
2. Turn off the vehicle and make sure all accessories are off.
3. Wait at least 30 minutes before using the memory saver. This ensures that the accessories are no longer
drawing current from the car battery.
4. Connect the memory saver's 12V connector to 12V port on the charger.
5. Press th Memory Saver button until the Memory Saver LED is lit.
6. Connect the memory saver's OBD connector to the vehicle's OBD plug. Make sure the connector is
fully engaged.
7. Push the START/STOP button.
8. Disconnect the vehicle's battery cables and cover the positive and negative cables with an insulator,
such as electrical tape. This prevents the connectors from touching metal, each other, or the chassis
and causing a short circuit, due to the vehicle's electrical system receiving power from the memory
saver through the OBD connection.
WARNING: When working with the vehicle's battery, review all of the battery manufacturer's safety
instructions, warnings and directives regarding battery disconnection, removal and replacement.
9. Remove the old battery and put the new battery into position.
10. Remove the insulator from the positive cable and connect it to the positive terminal of the new battery.
11. Remove the insulator from the negative cable and connect it to the negative terminal of the new battery.
12. Press the START/STOP button to turn off the memory saver.
13. Once the new battery is connected, unplug the memory saver's OBD connector from the vehicle's
OBD plug.
