USING THE MEMORY SAVER/DETECTOR
Use the memory saver/detector cable 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: 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, 85-100 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 85-100 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
85-100 into the power outlet within the same vehicle
from which you are removing the battery.
4. Connect the 85-100’s 12V OBD 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 PROCEED LED in box #3 lights, do not
disconnect the vehicle’s battery; disconnect the 85-100
and check the internal fuse or contact a qualified service
personnel for electrical system repair.
