Test NS-9A - Repairing A No Crank Condition

WARNING: This page is about a different car, the 1995 Jeep Wrangler, 1995 Jeep Grand Cherokee, and 1995 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST NS-1A  before proceeding with this test. For connector terminal identification, see CONNECTOR IDENTIFICATION  at beginning of article. For wiring diagrams, see WIRING DIAGRAMS  at the end of this article. Perform TEST VER-1A  after each repair.
  1. If vehicle is equipped with a manual transmission, go to TEST NS-9B  . If vehicle is equipped with an automatic transmission, ensure transmission is in park. Using scan tool, read park/neutral position switch sense. If switch sense is park, go to next step. If switch sense is not park, repair open in park/neutral position switch ground circuit.
  2. Locate starter relay in Power Distribution Center (PDC). Disconnect starter relay and ensure connector is clean and not damaged. Using scan tool in voltmeter mode, check voltage on fused battery voltage circuit at relay connector terminal "B" (Black/Red wire on XJ body, Red wire on YJ body, or Red/Violet wire on ZJ body). If voltage is more than 10 volts, go to next step. If voltage is less than 10 volts, repair open in fused battery voltage circuit.
  3. Using scan tool in voltmeter mode, check voltage on ignition switch output circuit at relay connector terminal "A" (Yellow wire on XJ and YJ bodies or Yellow/Black wire on ZJ body). If voltage is more than 10 volts, go to next step. If voltage is less than 10 volts, repair open in ignition switch output circuit.
    WARNING: Before proceeding with next step, ensure transmission is in park, parking brake is set and drive wheels are blocked. Keep hands, loose clothing or jewelry away from moving engine part. Engine may be cranked in next step.
  4. Briefly connect a jumper wire between starter relay connector terminal "B" (Black/Red wire on XJ body, Red wire on YJ body, or Red/Violet wire on ZJ body) and terminal "D" (Brown wire) and go to TEST NS-9C  .
