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 will not complete
  2. With the ignition switch off, ground the Brown wire in terminal #9 of the OBD-II connector
  3. Turn the ignition switch on and do not depress the brake pedal
  4. The ABS indicator turns on and then goes out after 2 seconds
  5. After the ABS indicator goes out, the press and release the VSA off button once within 0.5 seconds
  6. After the ABS indicator turns on again, the press and release the VSA off switch once within 0.5 seconds
  7. The VSA activation indicator should sound blink 2 times and go off in one second, then the system completes the neutral position memorization. If the lights do not go out, repeat the procedure 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.
