Suspension Control ( Automatic - Electronic Level )

DIAGNOSTIC TROUBLE CODE CHART

C1711 - C1739:

C1740 - C1777:

U0100 - U0132:

HINT:
- If an abnormality is not found when the parts are inspected, inspect the suspension control ECU.
- If a trouble code is displayed during the DTC check, check the circuit listed for that code. For details of each code, "DTC No." in the DTC chart.

*1 :For codes in the "Indicator Light" column with a "°" mark, the absorber control indicator lamp blinks at 1 second intervals.
*2: For codes in the "Indicator Light" column with a "(°)" mark, when trouble occurs, "HEIGHT HI" is displayed on the multi-information display. Also, the master warning light is lit on the combination meter and an alarm sounds.
*3: Since the relief pressure of the compressed air is 980 kPa (10 kgf/sq.cm, 142 psi), if vehicle height control is attempted on a steeply sloping road, when the vehicle is overloaded, or when the vehicle height is jacked up with the engine running, code "C1751" may be output and vehicle height control may be suspended. (This is not abnormal.) In this case, however, when detecting the first error, approximately 10 minutes after the ignition switch was turned to the ON position, vehicle height control is resumed. When the following errors are detected, it takes 70 minutes until the control is resumed.
*4: If vehicle height control is operated while the wheels are removed or the vehicle is jacked up, code "C1752" may be output, but this is not abnormal. When code "C1752" is output, vehicle height control is not carried out. However, control is resumed if the ignition switch is turned off, then to the ON position again.

C1786 - C1793:

DTC of Air Suspension System test mode function:
If a malfunction code is displayed during the test mode DTC check, check the circuit listed for that code. For details of each code, refer to "the respective "DTC No." in the chart.
