got a 2006 TSX, VSC, ABS, BRAKE are all on. I manually checked the ABS codes, im getting 5-4. This should be the pump.

was wondering if there is a relay or fuse for the ABS system?

 

does anyone know how to remove the connector on the VSA ABS modulator?

 

From shop manual (sorry I can't print a file w/ my manual), fault is either:

1) a ground fault to the VSA Modulator Control Unit, (Pin 47 of 47 pin connector, right lower corner pin looking at connector from wire side). Check for ground to this pin. If ground is missing, the repair ground wire.

or

2) VSA Modulator Control Unit fault. Reset VSA Modulator Control Unit (see attached manual procedure) and drive. If code returns, then replace control unit. See ebay and car-part.com for a used unit.

Suggest getting your own shop manual to have pin diagram and other info. Check ebay and automanualsource.com.

good luck
