BELMS12OBDL - ON-BOARD-DIAGNOSTICS II MEMORY SAVER DETECTOR
ENGLISH
USING THE MEMORY SAVER DETECTOR
Use the memory saver detector cable to save the vehicle's on-board diagnostic computer set-
tings (radio programs, diagnostic codes, etc.) while the battery is disconnected from the vehicle
during repair or maintenance.
NOTE: 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 the power source used is greater than or equal to 12VDC. If using a portable
battery device, make sure it is fully charged.
2. Turn off the vehicle, remove the key, and make sure all accessories are off.
WARNING: Verify all vehicle accessories are OFF (fan, interior lights, etc.). Headlights must be in
OFF position, not AUTO position. To prevent overloading of a vehicle fuse, BELMS12OBDL fuse or
other vehicle damage, do not use the memory saver through the OBDII port if the vehicle's current
draw is 4 amps or more when the vehicle is in a KEY OFF condition (use an amp clamp to measure
the amperage draw). If unable to measure the vehicle's current draw, turn the vehicle's key to the
OFF position and wait 25 minutes. This ensures that all retained accessories are in a power OFF
state (for example: fan, headlights, etc.).
3. Connect the 12V power plug of the BELMS12OBDL to your 12V DC power supply. Make sure plug
is firmly in place. The yellow CONNECTED LED in box #1 will light, indicating a good connection.
WARNING: Do not connect the 12V power plug of the BELMS12OBDL into the power outlet within
the same vehicle from which you are removing the battery.
4. Connect the BELMS12OBDL diagnostic connector to the vehicle's OBD plug. Make sure the
connector is fully engaged. The yellow CONNECTED LED in box #2 will light, indicating a good
connection.
5. Verify that the green PROCEED LED in box #3 is lit, indicating
you may disconnect the vehicle's battery. If the red DO NOT PRO-
CEED LED in box #3 lights, do not disconnect the vehicle's bat-
tery; disconnect the BELMS12OBDL and check the internal fuse
or contact a qualified service personnel for electrical system repair.
6. 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 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.
