NO RESPONSE Message
- 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.
- 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.
- 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.
