Bench Testing: Diodes

WARNING: This page is about a different car, the 2004 Toyota Camry Solara and 2003 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Testing is for 2003 models only. Testing for 2004 models is not available from manufacturer.
  1. With diode/rectifier assembly removed and on bench, contact positive diode plate terminal with one ohmmeter probe. Using other ohmmeter probe, contact each diode lead in same plate. Note ohmmeter reading. Reverse ohmmeter probes, and repeat tests for all diodes.
  2. All diodes should show continuity in one direction and no continuity in opposite direction. If any diode is defective, replace diode/rectifier assembly.
