My speed reads zero while driving.
There could be a number of things wrong. Make sure the
DriveRight 600 is plugged in. Make sure the DriveRight
600 is calibrated. Make sure the speed sensor is within 10-
16 mm (3/8"- 5/8") of the magnet. Make sure the unit is not
running on battery power (see “Battery Operation” on
page 24). If it is check the fuse in the power line. If all of
this fails to solve the problem, consult the trouble shooting
section of your Installation Guide.
The speed reading on the DriveRight 600 agrees with my vehi-
cle’s speedometer, but the distance reading on the DriveRight
600 and my odometer differ (or vice versa).
For best accuracy, you should calibrate using the car’s
odometer (see “Calibration Using the Odometer” on
page 8). You may readjust the unit’s calibration periodi-
cally (to maintain accuracy) use the PLUS and MINUS but-
tons to readjust the distance reading to match the vehicle’s
trip meter reading after a long trip.
The DriveRight 600 seems to be recording erroneous read-
ings at low speeds.
Excessive mechanical vibrations at low speeds can cause
erroneous readings. Have your installation checked if you
have this problem.
The DriveRight 600 indicates erroneous decelerations at low
speeds (VSS models only).
On some cars, the wrong dip switch settings can cause the
DriveRight 600’s speed reading to abrutly drop to zero at
around 10 to 13 mph, which generates an erroneous decel-
eration log. Check your VSS cable dip switch settings if
you have this problem.
The display is black or all the segments appear to be on.
The display was left in direct sunlight. The display will
return when it cools down. Even though the display is
black, the DriveRight 600 continues to record data.
The tamper light won’t go off.
Enter your security code (see “Tamper Log” on page 24).
I’ve forgotten my secret code.
If you have the software, you can read the vehicle’s code.
Otherwise, ship the unit back to us with a check for $25.00
and a note explaining the situation. We will return the unit
to you with the code set to 0000.
