Subject: TESTING "SPEEDOMETER OPERATION AND ACCURACY USING" HI-SCAN PRO
DESCRIPTION:
This TSB will provide instructions on how to test the vehicle's speedometer gauge for proper operation and accuracy using the Hi-Scan Pro's "Sensor
Simulator" function. This procedure is recommended as the first step in diagnosing speedometer operation and accuracy.
Vehicles that can be tested using the following procedure:
PROCEDURE
1. Ensure that your Hi-Scan Pro has the latest SOL Application Software Card.
2. Connect the DLC connector of your Hi-Scan tool to the vehicle's DLC port.
3. Turn the vehicle's ignition to the "ON" position. (do not start the vehicle).
4. Turn the Hi-Scan Pro tool on.
5. On the "INITIAL SCREEN", select "TOOL BOX (DVOM/SCOPE)".
6. Next, on the "TOOL BOX (DVOM/SCOPE)" screen, select "SENSOR SIMULATOR".
7. After selecting the sensor simulator function, a cautionary statement related to the "Channel B test probe" (not used in the procedure) will be
displayed. Press any key to continue.
8. The "SENSOR SIMULATOR" screen will now be displayed. The default function is VSS, vehicle speed simulation.
9. Enter a target test speed by using the "+" and "-" keys.
10. A target test speed of 20 MPH entered into the Hi-Scan Pro should result in a readout on the vehicle's speedometer of 20 MPH, plus or minus the
tolerance specified in step 13.
11. A target test speed of 100MPH entered into the Hi-Scan Pro should result in a readout on the vehicle's speedometer of 100MPH, plus or minus the
tolerance specified in step 13.
12. If diagnosing a suspected non-operational speedometer and the target test speed is displayed, the speedometer is functioning properly and focus
should be placed on testing the Vehicle Speed Sensor, physical connections, and wiring. Refer to the appropriate Electrical Troubleshooting Manual and
Shop Manual for complete diagnostic procedures.
13. If diagnosing speedometer accuracy, use the tolerance chart to determine if the speedometer gauge is within proper specifications.
