. Perform TEST VER-1 after each repair.
- Disconnect DRB. Using an external voltmeter, check voltage between chassis ground and Data Link Connector (DLC) terminal No. 2 Red wire. DLC is located under dash, left of steering column. If voltage is less than 10 volts, repair Pink wire or Red wire as necessary.
- If voltage is more than 10 volts, turn ignition off. Using an external ohmmeter, check resistance between chassis ground and DLC terminal No. 6 (Black/Light Green wire). If resistance is more than 20 ohms, repair open in Black/Light Green wire.
- If resistance is less than 20 ohms, try a different DRB adapter cable. If DRB screen is no longer blank, replace defective DRB adapter cable.
- If DRB screen is still blank, try a different DRB cartridge. If DRB screen is no longer blank, replace defective DRB cartridge. If DRB screen is still blank, replace defective DRB.
