Input Check
If self-diagnostic check is necessary, perform self-diagnostic check before performing input check. See SELF-DIAGNOSTIC CHECKΒ under TESTING. Input check should be made if no self-diagnostic codes exist, cruise control system cannot be set and when necessary to check if input signals are normal. Input check display codes are displayed only if circuit is normal according to conditions in INPUT CHECK DISPLAY PATTERNS chart. See Fig 1 . To access input check display codes, proceed as follows.
