Action Taken When the DTC Sets
The LEVELING indicator lamp will flash while this DTC is present. The
function of the ALC system may be degraded or disabled, depending upon which
error has been detected.
Conditions for Clearing the DTC
The position data out of range and the A/D conversion error are checked
continuously and may be recovered during the same ignition cycle. All other
errors are checked during the start up self test at each ignition cycle.
The DTC will clear when no error is detected and the cause for the error
has been repaired.
