CHAPTER 22 - 22The CPU detects the following failures and error by monitoring /BDI signal sent from the BD sensor, and reports itto the interface controller:1) Scanner FailureWhen the /BDI cycle does not reach the specified value within 3.5 seconds after the scanner motor was forciblyaccelerated at its start-up.2) BD failureWhen the /BDI signal is not detected within 0.1 seconds after the scanner motor was forcibly accelerated. Or, thescanner became ready once and then the /BDI cycle is not detected in the specified value for 2 continuous seconds.3) BD errorWhen the /BDI signal is not detected in the specified cycle while the engine controller is outputting the /BD signalto the interface controller.The CPU does not report the BD error to the interface controller, if it detects a door open within 0.2 seconds afterdetecting a BD error.Also, the CPU cancels the BD error, if it detects a scanner failure or BD failure after detecting the BD error.
