DECEMBER, 2005TESTING SPEEDOMETER OPERATION AND ACCURACYUSING HI-SCAN PRO

DESCRIPTION:

This TSB will provide instructions on how to test the vehicles speedometer gauge forproper operation and accuracy using the Hi-Scan Pros Sensor Simulator function.This procedure is recommended as the first step in diagnosing speedometer operationand 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 vehicles DLC port.

3. Turn the vehicles 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 fuction, a cautionary statement related to theChannel B test probe (not used in the procedure) will be displayed. Press anykey to continue.

8. The SENSOR SIMULATOR screen will now be displayed. The default function isVSS, vehicle speed simulation.

9. Enter a target test speed by using the + and - keys.

10. A target test speed of 20MPH entered into the Hi-Scan Pro should result in areadout on the vehicles speedometer of 20MPH, plus or minus the tolerancespecified in step 13.

11. A target test speed of 100MPH entered into the Hi-Scan Pro should result in areadout on the vehicles speedometer of 100MPH, plus or minus the tolerancespecified in step 13.

12. If diagnosing a suspected non-operational speedometer and the target test speedis displayed, the speedometer is functioning properly and focus should be placed

on testing the Vehicle Speed Sensor, physical connections, and wiring. Refer tothe appropriate Electrical Troubleshooting Manual and Shop Manual for completediagnostic procedures.

13. If diagnosing speedometer accuracy, use the following tolerance chart todetermine if the speedometer gauge is within proper specifications.

14. If the speedometer displays target test speeds correctly while connected to the

Hi-Scan, but appears to be out of specification during road speed tests, focusshould be placed on testing the Vehicle Speed Sensor, checking tire pressure, andtire/wheel rolling diameter. Refer to the appropriate Electrical TroubleshootingManual and Shop Manual for complete diagnostic procedures.
