  1. Perform POWER SUPPLY CIRCUIT CHECK under PRELIMINARY CHECK. Check TCU output for wiper relay circuit. Turn wiper switch to INT. Turn ignition switch to ACC. Measure voltage between terminals 15 and 2 of TCU harness connector. Voltage should vary between 12V and 0V every 3 to 12 seconds. If output is not as specified, go to step 2). If output is okay, check wiper relay operation. If relay is okay, check harness between TCU and wiper relay. If relay is not okay, replace relay.
  2. Check wiper switch circuit. Turn wiper switch to INT. Turn ignition switch to OFF. Measure voltage between terminals 12 and 2 of TCU harness connector. Voltage should be 0V with wiper switch in INT, and 12V with wiper switch OFF. If voltage is as specified, replace TCU. If voltage is not as specified, check harness between TCU and wiper switch. If harness is okay, replace wiper switch.

INTERMITTNET TIME OF WIPER CANNOT BE ADJUSTED

Check intermittent wiper volume circuit. Turn ignition switch OFF. Connect ohmmeter between terminals 16 and 2 of TCU harness connector. Resistance should be approximately 15 Ohms at "<<<" position and 1.8k Ohms at "<" position. If resistance is as specified, replace TCU. If resistance is not as specified, check harness between TCU and wiper volume switch. If harness is okay, replace wiper switch.

WIPER AND WASHER ACTIVATE INDIVIDUALLY BUT NOT TOGETHER

  1. Check washer switch circuit. Turn ignition switch to ACC or ON position. Connect voltmeter between terminals 14 and 2 of TCU harness connector. Pull washer switch ON. In wash position, voltage should be 0V. In neutral position, voltage should be 12V. If voltage is as specified, go to step 2). If voltage is not as specified, check harness between TCU and washer switch.
  2. Check TCU output to wiper motor. Connect voltmeter between terminals 15 and 2 of TCU harness connector. Pull washer switch ON. Voltage should be 0V for approximately 2.5 seconds after releasing switch, then return to 12V. If voltage is okay, replace wiper relay. If voltage is not okay, replace TCU.

INTERIOR LAMP DOES NOT FADE OUT AFTER DRIVER'S DOOR IS CLOSED

  1. Perform POWER SUPPLY CIRCUIT CHECK under PRELIMINARY CHECK. Check driver's door switch. Turn ignition switch OFF. Open driver's door. Connect a voltmeter between terminals 21 and 2 of TCU harness connector. When door is open, voltage should be 0V. When door is closed, voltage should be 12V. If voltage is as specified, go to step 2). If voltage is not as specified, check harness between TCU and driver's door switch and driver's door switch.
  2. Check TCU output for interior lamp circuit. Turn ignition OFF. Connect voltmeter between terminals 22 and 2 of TCU harness connector. Voltage should be 0V when door is open and rise from 0V to 12V once door is closed. If voltage is as specified, check harness between TCU and interior lamp. If voltage is not as specified, replace TCU.

ILLUMINATION CONTROL SYSTEM DOES NOT ACTUATE

  1. Check TCU output for light switch circuit. Turn ignition switch OFF and light switch ON. Connect voltmeter between terminals 9 and 2 of TCU harness connector. Voltage should be 12V. If voltage is as specified, go to step 2). If voltage is not as specified, check harness between TCU and light switch.
  2. Check illumination circuit. Turn ignition switch OFF and light switch OFF. Connect voltmeter between terminals 9 and 25 of TCU harness connector. Voltage should be 0V. If voltage is as specified, go to step 3). If voltage is not as specified, check for loose harness connector.
