No Response Message

  1. Connect DRB-II to another vehicle. If DRB-II displays NO RESPONSE message again, DRB-II or cable adapter are faulty. Substitute to find faulty component. If message screen does not display NO RESPONSE, DRB-II and cable adapter are functioning properly. Go to next step.
  2. Turn ignition off. Disconnect DRB-II. Using an ohmmeter, check Pink or Black/Red wire for resistance between SBEC and engine diagnostic connectors. If resistance is more than 10 ohms, repair open in Pink or Black/Red wire.
  3. If resistance is less than 10 ohms, check Light Green/Orange or Black/Pink wire for resistance between SBEC and engine diagnostic connectors. If resistance is more than 10 ohms, repair open in Light Green/Orange or Black/Pink wire.
