Toyota Coaster Instrumentation System Circuit Diagram

(6) Instrument system circuit

The Coast passenger car dashboard mainly includes a fuel gauge, a water temperature gauge, an engine tachometer, and a speedometer. In addition to the introduction of the ignition switch IG end, these meters are in common with each other in series with their own sensors, and the head also has terminals that are directly connected to the ground. Most of them are double-coil magnetic rotor pointers. table.

There are a number of indicator lights or warning lights inside the instrument panel in series with the sensor or sensor switch; there are some indicators that have one end of the instrument panel inside the ground and the other end connected to the relevant switch. In the former case, there are: T-BELT indicator, charging indicator, Turbo indicator, fuel overdose warning light, brake fluid low warning light, air filtration Blockage warning light, engine oil level warning light, preheating indicator, overspeed disconnect (O/DOFF) indicator, seat belt warning light, low oil pressure warning light, safety door warning light, parking (parking) Brake indicator, right turn indicator, left turn indicator, exhaust brake indicator. In the latter case, the indicator light has a high beam indicator, a hazard warning indicator, and the automatic transmission uses a power shift (ECTPOWER) mode indicator.

The instrument panel is connected to the external circuit by three connectors A, B and C, and 16 terminals of the B connector. There are 13 terminals of A and C connectors, and the components connected to these terminals are shown in Figure 16.
