Some vehicles sold by Honda & Acura in the mid 2000s may require a VSA calibration after clearing ABS or VSA codes.

If you clear your ABS codes and then an orange master warning triangle appears, or you read an 84 code you may need to perform the following calibration:

Do not attempt a VSA calibration yourself unless you understand all steps and are familiar with the OBDII port and vehicle.

Failure to follow steps., or attempting the following steps on an unsupported vehicle may cause damage to vehicle electrical systems or control modules. 

  1. Park the vehicle on a flat level surface
    If the vehicle is not perfectly level the calibration may not complete
  2. With the ignition switch off, ground the wire in terminal #9 of the OBD-II connector using a piece of wire
    The ground can be found on terminals #4 and #5
  3. Turn the ignition switch on without pressing the brake pedal
  4. The ABS/VSA indicator will first turn on and then go out after 2 seconds
  5. After the ABS/VSA indicator goes out, press and release the 'VSA Off' button once within 0.5 seconds
  6. Once the ABS/VSA indicator turns on again, press and release the 'VSA Off' button once within 0.5 seconds
  7. The ABS/VSA indicator should now blink 2 times and go out in roughly one second.
  8. Calibration should now be complete - if the VSA light stays on check for stored codes and address them as appopriate.
    If there are no stored codes attempt calibration again.

    When connecting to ground on step #2 this is either pin 4 or 5 (both are ground points) in the diagram below
    Exercise extreme caution when connecting pin #9 to ground, if you get the port layout backwards you may accidentally connect pin #16 (battery voltage) which is on the other side of the DLC to ground.
