The combination of set bits will determine the BITE result number. If all tests passed, the
BITE result displayed will be "BITE PASS". If BITE PASS is not displayed, and error has occurred. For
example, if bits 0 and 3 were set because their corresponding tests failed, the BITE result displayed will be
"BITE 009" (binary equivalent 00000000 00001001). If an error is encountered, the operator may attempt to
turn the receiver's power off then back on from a cold start to rerun the BITE function. If an error persists, a
hardware failure has been encountered.
