    • If there is no continuity, check for:
      • An open in the wire.
      • Poor ground (G 601).
  4. Measure the voltage between No. 4 terminal and body ground with the ignition switch ON (II).
    • If there is battery voltage, go to step 5.
    • If there is no voltage, check for:
      • Blown No. 21 (10A) fuse in the driver's under-dash fuse/relay box.
      • An open in the wire.
  5. Measure the voltage between No. 5 terminal and body ground with the ignition switch ON (II) and the transmission range switch in R position.
    • If there is battery voltage, replace the mirror assembly.
    • If there is no voltage, check for:
      • An open in the wire.
      • Faulty driver's under-dash fuse/relay box.
