Test No. 1
- Check for battery voltage at DLC terminal No. 16 (Red/Black wire). If battery voltage is not present, go to next step. If battery voltage is present, go to step 5).
- Check for battery voltage at Joint Connector 1 (J/C 1) terminal No. 6 (Red/Black wire). Connector is located behind top left of instrument panel. If battery voltage is present, go to step 5). If battery voltage is not present, go to next step.
- Check for battery voltage at joint connector terminal No. 3 (Red/Black wire). If battery voltage is present, repair connector. If battery voltage is not present, go to next step.
- Check for battery voltage at junction block connector B-50 (behind right kick panel) terminal No. 10 (Red/Black wire). If battery voltage is present, repair open Red/Black wire.
- Using an ohmmeter, check for continuity between ground and DLC connector terminals No. 4 (Black wire) and No. 5 (Black/White wire). If continuity is not present, repair open to ground. If continuity is present, scan tool is faulty. Retest using a known-good scan tool.
