  3. Check for continuity between terminal No. 6 and body ground.
    • If there is continuity, go to step 4.
    • If there is no continuity, check for:
    • An open or high resistance in the ground wire.
    • Poor ground (G601).
  4. Measure the voltage between terminal No. 4 and body ground with the ignition switch turned to ON (II).
    • If there is battery voltage, go to step 5.
    • If there is no voltage, check for:
    • Blown No. 21 (10 A) fuse in the driver's under-dash fuse/relay box.
    • An open or high resistance in the wire.
  5. Measure the voltage between terminal No. 5 and body ground with the ignition switch turned to 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 or high resistance in the wire.
    • Faulty driver's under-dash fuse/relay box.
    • Faulty transmission range switch.
    • Poor ground (G101).
