3. Once plugged in, the console should display the Current Readings
screen. If the display remains blank, check if the battery is properly
installed in the unit. If it is, press MODE. If it remains blank, check
the adapter cable and harness cable connections.
Configure the VSS Signal Settings
Because not all VSS signals are the
same, you may need to change the
default DIP switch setting on the
VSS in-line circuit.
• Switch 1 is used for square wave
VSS signals which do not go to ground.
• Switch 2 AC couples the signal in and is used for sine wave VSS
signals.
• Switch 3 improves the sensitivity of AC coupled signals.
• Switch 4 turns on the LED test circuit.
Refer to the VSS DIP Switch Flow Chart on the following page when
performing these steps:
1. Set the DIP switch as shown at the top of the chart.
2. Be sure to turn on switch 4 to enable the test LED.
Note: On the DIP switch, 0 (zero) is OFF and 1 is ON.
3. Test drive the vehicle and observe the green test LED.
Note: The DriveRIght unit must be plugged in for the LED to flash.
4. Refer to the flow chart and adjust the switch settings accordingly.
5. Repeat steps 2 and 3 as necessary to finish configuring the VSS sig-
nal.
6. Don’t forget to turn off the test LED, switch 4, when you are done.
Test and Calibrate the Installation
1. Go for a test drive and check the DriveRight speedometer reading.
The reading will usually be incorrect unless the console was
previously calibrated for your vehicle.
Note: It is possible that the unit may sound an alarm unexpectedly during an initial test
drive. The alarm can be caused by incorrect calibration along with the alarm
being set or just by the login alarm being set. Enter a Driver ID code on the unit to
silence the login alarm. If this does not work, you need to turn the alarm off. Con-
sult the DriveRight 600E User’s Guide for specific instructions on entering a
Driver ID code or turning off the alarm.
2. Refer to DriveRight 600E User’s Guide for calibration instructions
and calibrate the unit. If the speed is still incorrect, refer to the
VSS Dip Switch
