DTC 001

CONDITIONS FOR SETTING THE DTC
This Diagnostic Trouble Code (DTC) sets when the automatic level control sensor detects an internal hardware error or a software error. Examples of these errors are listed below:
^ Position data out of range
^ History code block error
^ Trim-set block error
^ Calibration block error
^ A/D conversion error
^ Ram integrity error
^ Read/Write to EEPROM error

ACTION TAKEN WHEN THE DTC SETS
The LEVELING indicator lamp will flash while this Diagnostic Trouble Code (DTC) is present. The function of the Automatic Level Control (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 Diagnostic Trouble Code (DTC) will clear when no error is detected and the cause for the error has been repaired.

DIAGNOSTIC AIDS
^ Cycle the ignition.
^ Use the scan tool in order to re-test for Diagnostic Trouble Code (DTC) 01.
^ If DTC 01 is still present, replace the automatic level control sensor.
