TEST 5A - Testing DRB-II

WARNING: This page is about a different car, the 1992 Dodge Dynasty, 1992 Chrysler New Yorker Fifth Avenue, 1992 Chrysler New Yorker, and 1992 Chrysler Imperial. However, it is still accessible from the selected car via links, so may be relevant.

Although the manufacturer is the only one equipped to physically test the DRB-II for proper operation, you should be able to determine the state of your DRB-II by using the following substitution techniques and the process of elimination.

Turn ignition switch to OFF position. Disconnect DRB-II adapter cable and DRB-II cartridge. Locate a second vehicle with identical equipment to original vehicle. Connect DRB-II assembly to second vehicle and turn ignition switch to ON position. Use DRB-II as it was used on first vehicle. If DRB-II results are not the same as before, problem is not with the DRB-II. Return to test that sent you here.
If same problem still exists as before substituting vehicles, DRB-II has a defective adapter cable or DRB-II cartridge. If a second DRB-II cartridge for the same vehicle is available, try substituting DRB-II cartridge. If DRB-II now functions correctly, original DRB-II cartridge is defective. Use the good DRB-II cartridge and return to test that sent you here.
If DRB-II still does not function correctly, substitute a second DRB-II adapter cable. If a second DRB-II adapter cable of same type is not available, use a SCI or CCD adapter cable. If DRB-II now functions correctly, DRB-II has a defective adapter cable. Use the good adapter cable and return to test that sent you here.
If DRB-II still does not work, substitute a second DRB-II. If a second DRB-II is not available, send DRB-II in for repair. If DRB-II now functions correctly, original DRB-II is defective. Use the good DRB-II and return to test that sent you here.
