WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
- To access volt-ohmmeter mode of DRB, connect Red volt-ohmmeter test lead to Red port, located on right top side of DRB.NOTE: Because DRB is grounded through engine diagnostic connector, only one volt-ohmmeter test lead is required when using volt-ohmmeter option. DRB volt-ohmmeter should only be used when self-diagnostics tests require the use of this option.
- To access voltmeter, press VOLT/OHM key once. DRB is now in voltmeter mode. Touch test probe to connector or wire to be measured. Read voltage on DRB display. When voltage testing is complete, press VOLT/OHM key 3 times to exit voltmeter mode.
- To access ohmmeter, press VOLT/OHM key twice. DRB is now in ohmmeter mode. Touch test probe to connector or wire to be measured. Read resistance to circuit ground on DRB display. When resistance testing is complete, press VOLT/OHM key twice to exit ohmmeter mode.
