Test 29A - All BRAKELIGHTS Out

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For appropriate wiring diagram, see WIRING DIAGRAMS  at end of article.
  1. Disconnect brakelight switch 6-pin connector (on brake pedal bracket). Using DRB-II in voltmeter mode, check voltage on terminalNo. 4 (Pink/Dark Blue wire) of brakelight switch 6-pin connector. If voltage is more than 10 volts, go to TEST 29B. If voltage is less than 10 volts, remove and inspect fuse No. 2 from fuse block. See Figure . If fuse is blown, go to TEST 29C  .
  2. If fuse No. 2 is okay, check voltage of Red/White wire (in fuse block) of fuse No. 2. If voltage is more than 10 volts, repair open in Pink/Dark Blue wire between fuse block and brakelight switch. Perform VERIFICATION PROCEDURE VER-1. If voltage is less than 10 volts, ensure headlights are off. Remove and inspect 50-amp fuse "C" in power distribution center. See Figure . Power distribution center is located in engine compartment, near left shock tower. If fuse "C" is blown, go to step 4).
  3. If fuse "C" is okay, check voltage of Black wire (in power distribution center) of fuse "C". If voltage is more than 10 volts, repair open in Red/White wire between power distribution center and fuse block. Perform VERIFICATION PROCEDURE VER-1. If voltage is less than 10 volts, repair or replace power distribution center. Perform VERIFICATION PROCEDURE VER-1.
  4. Turn ignition off. Using DRB-II in ohmmeter mode, check resistance of Red/White wire (in power distribution center) of fuse "C". If resistance is less than 5 ohms, repair short to ground in Red/White wire between power distribution center and fuse block. Also replace fuse "C". Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, replace fuse "C". Perform VERIFICATION PROCEDURE VER-1.
