Input Check (Galant With ETACS)

  1. Use Multi-Use Tester (MB991341) to ensure input signals from switches are being sent to ETACS control unit.
  2. Connect tester to diagnostic connector, located on left side kick panel, just right of fuse block. Turn ignition switch to ACC position.
  3. Select appropriate test on tester. Tester should buzz once when each switch or sensor is activated. If buzzer sounds, switch or sensor signal is being sent to control unit.
  4. If buzzer does not sound, a problem exists in that switch, sensor or wiring. Circuit(s) must be checked. See Figure -Figure . When checking vehicle speed sensor input, jack up front of vehicle and rotate tires in forward direction.
