Code
Description Causes
230
FGATE ON error The FGATE signal does not assert within the prescribed time. [The BICU generates the FGATE signal and sends it to the LD unit when the registration sensor switches on.]
231
FGATE OFF error The FGATE signal does not assert within the prescribed time. [The BICU generates the FGATE signal and sends it to the LD unit when the registration sensor switches on.] • BICU defective • BICU, Controller board harness loose or broken • Controller board defective.
240
LD error The IPU detected a problem at the LD unit. • Worn-out LD • Disconnected or broken harness of the LD.
270
X The I2C bus device ID is not identified during initialization. X A device-status error occurs during I2C bus communication. X The I2C bus communication is not established due to an error other than a buffer shortage Loose connection Defective IPU Defective LD controller board
302
