DTC B1301 5bow sensor: Up&Down=ON






CIRCUIT OPERATION

- The convertible top control module judges the convertible top operating state based on the signals from the sensors and switches.
- 5-bow sensor is the one of those sensors and the convertible top control module mounts 5-bow sensor (UP), 5-bow sensor (DOWN) (RH), and 5-bow sensor (DOWN) (LH). They output the following signals to the convertible top control module according to the open/close state of the convertible top.





DTC SET CONDITION

This DTC is set as a 5-bow sensor error when the 5-bow sensor (UP) and the 5-bow sensor (DOWN) output ON signal simultaneously which is unavailable in the normal condition.
In addition, if ON failure occurs in either LH or RH 5-bow sensor (DOWN), this DTC is also set. In this case, because the signals from the LH and RH sensors are different, DTC B1302 or B1303 is set at the same time.

TROUBLESHOOTING HINTS

- ON failure of 5-bow sensor (UP) (including defective sensor power supply line or signal line)
- ON failure of 5-bow sensor (DOWN) (including defective sensor power supply line or signal line)
- Malfunction of the convertible top control module

NOTE:
If ON failure occurs in both the LH and RH 5-bow sensors (DOWN), the power line for the 5-bow sensor may be defective.
