| DETECTION CONDITION |
- U3003:08
- While the vehicle is traveling at a speed of 10km/h {6.2 mph} or more, a CAN signal error caused by low power supply voltage is detected.
- U3003:16
- Low ignition voltage (7.9-9.6 V) is detected at the voltage monitor of the solenoid valve or motor monitor. (Except engine cranking condition)
- Low ignition voltage (6.0-7.9 V) is detected at the voltage monitor of the solenoid valve or motor monitor.
- Low ignition voltage (below 6.0 V) is detected at the voltage monitor of the solenoid valve or motor monitor.
- U3003:17
- High ignition voltage (17 V or more) is detected at the voltage monitor of the solenoid valve or motor monitor.
