SPECIFICATIONS WITH CONSULT-III
| CAUTION | The output signal indicates the EPS control unit calculation date. The normal values will be displayed even in the event that the output circuit (harness) is open. |
| Monitor item (Unit) | Content | Condition | Display value |
| MOTOR VOL (V) | Power supply voltage for EPS control unit | Ignition switch: ON | Battery voltage |
| TORQUE SENSOR (Nm) | Steering wheel turning force | Engine running | Steering wheel: Not steering (There is no steering force) | 0.00 Nm |
| Steering wheel: Steering | 0 - 8.19 Nm (1) (The value is changed according to steering left or right) |
| MOTOR SIG (A) | Command current to EPS motor | Engine running | Steering wheel: Not steering (There is no steering force) | 0.00 A |
| Steering wheel: Steering | 0 - 65.00 A (The value is changed according to steering left or right) |
| MOTOR CURRENT (A) | Consumption current of EPS motor | Engine running | Steering wheel: Not steering (There is no steering force) | 0.00 A |
| Steering wheel: Steering | 0 - 65.00 A (2) (The value is changed according to steering left or right) |
| VEHICLE SPEED (km/h) or (mph) | Vehicle speed | Vehicle stopped | 0 km/h (0 mph) |
| While driving | Approximately equal to the indication on speedometer (Inside of ±10%) (3) |
| WARNING LAMP (ON/OFF) | EPS warning lamp condition | EPS warning lamp: ON | ON |
| EPS warning lamp: OFF | OFF |
| DERATING STAT (ON/OFF) | Protect overload status | Engine running | Steering wheel: Normal steering | OFF |
| Steering wheel: Steering over the stop | ON (4) |
| ENGINE STATUS (RUN/STOP) | Engine status | Engine stopped (Engine speed: Less than 400 RPM) | STOP |
| Engine running (Engine speed: 400 RPM or more) | RUN |
| (1) In the front of the value"L" is displayed at steering left and "R" is displayed at steering right. (2) Almost in accordance with the value of "MOTOR SIG". It is not a malfunction though these values are not accorded when steering quickly. (3) It is not a malfunction, though it might not be corresponding just after ignition switch is turned ON. (4) It turns to OFF after waiting for a short period of time. |
