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 wire for continuity between SBEC connector terminal No. 25 and engine diagnostic connector. Check Pink wire for a short to ground. If continuity does not exist or wire is shorted to ground, repair open/shorted in Pink wire.
  3. If continuity exists and wire is not shorted to ground, check Light Green wire for continuity between SBEC connector terminal No. 45 and engine diagnostic connector. Check Light Green wire for a short to ground. If continuity does not exist or wire is shorted to ground, repair open/shorted in Light Green wire. If all systems check okay, replace SBEC. Reset EMR mileage.
