SYSTEM TESTS

WARNINGVehicles are equipped with air bag supplemental restraint system. Before attempting any repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in appropriate AIR BAG RESTRAINT SYSTEMS article in ACCESSORIES & EQUIPMENT.
CAUTIONWhen battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

Note. The following tests assume that engine and battery are operating normally and are at operating temperature, battery is charged, there are no engine problems that would cause a no-start condition, and no diagnostic trouble codes are present.

SYMPTOM INDEX

A/T

  1. If engine electrical diagnostic system check was not performed, go to «ENGINE ELECTRICAL DIAGNOSTIC SYSTEM CHECK»(ref-127854-S33022709532001102900000) under SELF-DIAGNOSTIC SYSTEM. If engine electrical diagnostic system check was performed, go to next step.
  2. Turn ignition switch to START position. If theft indicator light is flashing, repair anti-theft system as necessary. See appropriate ANTI-THEFT SYSTEMS article in ACCESSORIES & EQUIPMENT. If theft indicator light is not flashing, go to next step.
  3. Turn ignition switch to START position. If starter solenoid clicks, go to «TEST B: ENGINE DOES NOT CRANK, SOLENOID CLICKS»(ref-127854-S21824736652001102900000) . If starter solenoid does not click, go to next step.
  4. If engine cranks and runs normally, check electrical wiring system for intermittent and/or poor connections. If engine does not crank and run normally, go to next step.
  5. Connect scan tool to Data Link Connector (DLC). Turn ignition switch to RUN position. Place transmission in Park or Neutral. Using scan tool, observe TR SW parameter in PCM data list. If scan tool indicates PARK or NEUTRAL, go to next step. If scan tool does not indicate PARK or NEUTRAL, repair transmission related concern. See appropriate ELECTRONIC CONTROLS article in AUTOMATIC TRANSMISSIONS.
  6. Turn ignition switch to START position. Using a DVOM, measure voltage drop between positive battery terminal and Purple wire terminal at starter solenoid. If voltage drop is less than 0.5 volts, go to step 11 . If voltage drop is greater than 0.5 volts, go to next step.
  7. Turn ignition switch to START position. Using a DVOM, measure voltage drop between positive battery terminal and terminal "E" (Purple wire) at PNP switch connector C1. If voltage drop is less than 0.5 volts, go to next step. If voltage drop is greater than 0.5 volts, go to step 9 .
  8. Repair open or high resistance in Purple wire between PNP switch and starter. After repairs, go to step 17 .
  9. Turn ignition switch to START position. Using a DVOM, measure voltage drop between positive battery terminal and terminal "G" (Yellow wire) at PNP switch connector C1. If voltage drop is less than 0.5 volts, go to step 12 . If voltage drop is greater than 0.5 volts, go to next step.
  10. Check for open or high resistance in Yellow wire between terminal "B" at ignition switch connector C1 and terminal "G" at PNP switch connector C1. If problem exists, repair as necessary and go to step 17 . If problem does not exist, go to step 13 .
