Not measured the ones on the Jazz, but they're normally between 500Ω and 1.5kΩ. Any open circuit is an obvious problem, but the cables to the front move and a break may only be evident at certain steering angles.
There is another reasonably common issue that afflicts the Jazz, if yours has a few miles on it. The pump motor fails, usually it's the motor brushes that have worn out. The brushes are not made to be replaceable, but if you are reasonably handy, and adept with a soldering iron, they can be replaced without removing the pump or disturbing any brake lines.
A diagnostic with Honda HDS will report a series of codes for pump motor failure.
