C1752 LEXUS - Continuous Electric Current To Height Control Compressor

- Height Control Compressor harness is open or shorted
- Height Control Compressor circuit poor electrical connection
- Anti-Lock Brake System (ABS) Warning Light ON
- Engine Light ON (or Service Engine Soon Warning Light)
C1752 Lexus DescriptionIf the vehicle height control is attempted on a steeply sloping road, when the vehicle is overloaded, or when the vehicle is jacked up with the engine running, the compressor motor operates continuously to raise vehicle height, and causes electric current to flow to the AIR SUS relay for 100 seconds or longer. Thus DTC C1751/51 may be output and vehicle height control may be suspended. (This is not electrically abnormal.) In this case, however, the vehicle height operation is resumed approx. 10 min. after the ignition switch is turned ON after the ECU detects the first error. If ECU detects another error, it takes 70 minutes until control is resumed.
