1982 Toyota Pickup BaseFACTORY OEM SERVICE PROCEDURE

Computer & Sensor

  1. Remove side kick panel. Unplug wiring connector from computer. Inspect computer at connector on wire harness side. With ignition switch "ON" and using a voltmeter, measure the voltage between terminal 13 and body ground with the main switch "ON". See Fig 1. If there is no battery voltage, check the control switch.

  2. Using a voltmeter, measure the voltage between terminal 8 and body ground. When parking brake lever is pulled, voltage should be 0 volt. When parking brake lever is returned, voltage should be 12 volt.
  3. Turn ignition switch "OFF". Using a voltmeter, measure the voltage between terminal 11 and body ground. If there is no battery voltage, check the stop light switch.
  4. Using voltmeter, measure the voltage between terminal 12 and body ground. When brake pedal is depressed, voltage should be 12 volt. When brake pedal is returned, voltage should be 0 volt. If voltage is not correct, check the brake pedal switch.
  5. Turn ignition switch to "ACC". Using an ohmmeter, check the continuity between terminal 9 and body ground. On manual transmission models, check with clutch pedal depressed. On automatic transmission models, check when shift lever is in neutral position. If there is no continuity between terminals, check the clutch switch or neutral start switch.
  6. Using an ohmmeter, measure the resistance between the terminals. Resistance between 6-10 should be approximately 68 ohms. Resistance between 4-10 should be approximately 30 ohms. If the ohms are not correct, check the actuator.
  7. Using an ohmmeter, check the continuity between terminal 3 and body ground when the set switch is turned "ON". If there is no continuity between terminals, check the control switch.
  8. Using an ohmmeter, check the continuity between terminal 7 and body ground when the set switch is turned "ON". If there is no continuity between the terminals, check the control switch.
  9. Using an ohmmeter, check the continuity between terminal 5 and body ground when the cancel switch is pushed "ON". If there is no continuity between the terminals, check the control switch.
  10. Using an ohmmeter, check the continuity between terminal 1 and body ground when the vehicle is slightly pushed forward. At this time, the ohmmeter needle should repeatedly move from "ON" to "OFF". If the ohmmeter needle does not deflect, check the speed sensor.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
