Driver Side J/B ECU:
STD VOLTAGE
| Terminals No. (Symbols) | Wiring Color | Condition | STD Voltage (V) |
|---|---|---|---|
| 3 <=> 6 (IG <=> GND) | - | Ignition switch ON | 10 - 14 V |
| 4 <=> 6 (ACC <=> GND) | - | Ignition switch ACC | 10 - 14 V |
| 6 <=> Body ground (GND <=> Body ground) | - | Constant | Below 1 V |
| D2-12 <=> 6 (STOP <=> GND) | G-R <=> - | Brake pedal released (Stop light switch OFF) | Below 1 V |
| Brake pedal pushed (Stop light switch ON) | 7.5 - 14 V | ||
| D2-13 <=> 6 (STPI <=> GND) | G-W <=> - | Brake pedal pushed (Stop light switch ON) | Below 1 V |
| Brake pedal released (Stop light switch OFF) | 7.5 - 14 V |
If the value is not within the standard range, some defect on the vehicle side is plausible.
