| 1233/33 |
When any of the following 1. through 4. is detected:
- ECU terminal IG1 voltage is 9.5 V to 17.0 V, and the condition that yaw rate sensor voltage is out of the range from 0.25 V to 4.75 V continues for 1 sec. or more.
- The conditions that yaw rate sensor open detect circuit signal is ON and the voltage of ECU terminal IG1 is 9.5 V to 17 V continue for 1 sec. or more.
- The conditions that yaw rate sensor power source voltage is out of the range from 4.4 V to 5.6 V and the voltage of ECU terminal IF1 is 9.5 V to 17 V continue for 1 sec. or more.
- When the condition that yaw rate sensor signal is momentarily open occurs 10 times or more and the voltage of ECU terminal IG1 is 9.5 V to 17 V.

| C1234/34 |
Condition 1. or 2. is detected:
- When the conditions that yaw rate sensor VYS terminal voltage is 4.75 V to 5.25 V and YD malfunction signal of yaw rate sensor is ON continue for 5 sec. or more.
- Shift lever is in P position and output voltage of yaw rate sensor is out of the range from 2.4 V to 2.6 V or after the difference from zero point calibration voltage of yaw rate sensor becomes 0.08 V or more and when the condition that the vehicle speed exceeds more than 15 km/ h (9 mph) while output condition of yaw rate sensor is repeated more than 3 times.
