Input Check (Galant With ETACS)
- Use Multi-Use Tester (MB991341) to ensure input signals from switches are being sent to ETACS control unit.
- Connect tester to diagnostic connector, located on left side kick panel, just right of fuse block. Turn ignition switch to ACC position.
- 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.
- 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.
