TERMINALS OF ECU

1. CLOCK ASSEMBLY (IN HEATER CONTROL PANEL) (WITHOUT NAVIGATION SYSTEM)
HINT:
- Measure the voltage with the connector still connected.
- The whole heater control panel should be replaced if the clock assembly has a malfunction because this part is not independently supplied.













(a) Waveform (Reference): Using oscilloscope:





HINT: Duty ratio changes as the illumination becomes darker (the period "A" shown in the illustration becomes longer).

2. CLOCK ASSEMBLY (IN MULTI-DISPLAY) (WITH NAVIGATION SYSTEM)
HINT:
- Measure the voltage with the connector still connected.
- The whole multi-display assembly should be replaced if the clock assembly has a malfunction because this part is not independently supplied.













(a) Waveform (Reference): Using oscilloscope:





HINT: Duty ratio changes as the illumination becomes darker (the period "A" shown in the illustration becomes longer).
