Suspension Control ( Automatic - Electronic Level )

DIAGNOSTIC TROUBLE CODE CHART

C1711/11 - C1742/42:

C1751/51 - C1779/79:

HINT:
- Using SST 09843-18040, connect terminals Tc and CG of the DLC3.
- If any abnormality is not found when the parts are inspected, inspect the suspension control ECU.
- If a malfunction 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 "O" mark, the absorber control indicator light blinks at 1 second intervals.

*2: When a trouble occurs, "HEIGHT HI" is displayed in the multi-information. Also, the master warning light is lit on the combination meter and an alarm sounds.

*3: Codes with the "O" mark in the "Memory" column are stored in memory even when the ignition switch is OFF. For codes with the "-" mark, it does not memory.

*4: Since the relief pressure of the compressed air is 980 kPa (10 kgf/sq.cm, 142 psi), if the 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 "C1751/51" may be output and vehicle height control may be suspended. (This is not abnormal.) In this case, however, when detecting the first error, approx. 10 minutes after the ignition switch was turned ON, vehicle height control is resumed. When the following errors are detected, it takes 70 minutes until the control is resumed.

*5: If vehicle height control is operated while the wheels are removed or the vehicle is jacked up, code "C1752/52" may be output, but this is not abnormal. When code "C1752/52" is output, the vehicle height control is not carried out. However, the control is resumed if the ignition switch is turned OFF, then ON again.

DTC of the input signal check:

C1781/81 - C1797/97:

If a malfunction code is displayed during the test mode DTC check, check the circuit listed for that code. For details of each code, "DTC No." in the DTC chart.
