Коды неисправности воздушной подвески Toyota

Code	System	Blinking Pattern *	Diagnosis
—^(-)	—		Normal.
11^(O)	Height Control Sensor Front RH Circuit		• Open or short circuit in height control sensor circuit.
12^(O)	Height Control Sensor Front LH Circuit
13^(O)	Height Control Sensor Rear RH Circuit
14^(O)	Height Control Sensor Rear LH Circuit
21^(O)	Front Suspension control Actuator Circuit		• Open or short circuit in suspension control actuator circuit.
22^(O)	Rear Suspension Control Actuator Circuit
31^(O)	No. 1 Height Control Valve Circuit		• Open or short circuit in height control valve circuit.
33^(O)	No. 2 Height Control Valve Circuit (for right suspension)
34^(O)	No. 2 Height Control Valve Circuit (for left suspension)
35^(O)	Exhaust Valve Circuit		* Open or short circuit in exhaust valve circuit.
41^(O)	No. 1 Height Control Relay Circuit		• Open or short circuit in No. 1 height control relay circuit.
42^(O)	Compressor Motor Circuit		• Short circuit in compressor motor. • Compressor motor locked.
51*^3(-)	Continuous electric current to No. 1 height control relay		• Electric current is supplied to No. 1 height control relay for approx. 8.5 minutes or longer.
52*^4(-)	Continuous electric current to exhaust valve		• Electric current is supplied to exhaust valve for approx. 6 minutes or longer.
61	Malfunction ECU
71^(O)*5	Height Control ON/OFF Switch Circuit		• Height control ON/OFF switch is "OFF" position. • Short circuit in height control ON/ OFF switch circuit.
72^(-)	Suspension Control Actuator Power Source Circuit		• Open circuit in suspension control actuator power source circuit • AIR SUS fuse is burned out.
73^*5(-)	IC Regulator Circuit (Alternator Circuit)		• [REG] terminal voltage is less than 1.5V when engine is running.
74^*5(-)	Vehicle Height Control Power Source Circuit		• [(IGN) or (+B)] terminal voltage is less than 7.5-9.5V.
75^(-)	Height Control Sensor		• Detect uneven ground.

For codes with a 0 mark, the height control indicator "NORM" light blinks at 1 second intervals. For codes with the "—" mark, it does not blink.

Codes “ 11, 12, …,51, 52 ” are stored in memory even when the ignition switch is off.

Since the relief pressure of the compressed air is 10 kgf/cm², if vehicle height control is attempted on a steeply sloping road, or when the vehicle is overloaded, code "51" may be output and vehicle height control may be suspended. (This is not abnormal.) However, in this case, approximately 70 minutes after the ignition switch is turned on, vehicle height control is resumed.

If vehicle height control is operated while removing wheels or while jacking up the vehicle, code "52" may be output, but this is not abnormal. When code "52" is output, vehicle height control is not carried out. However, control is resumed if the ignition switched is turned off, then on again.

When the height control ON/OFF switch is in the "off" position, diagnostic code "71" is output.

* В том числе, соответствует a 1991Toyota Soarer 4.0 GT-L (UZZ31-ACPZK)

Note: Для систем с электронным информационным табло возможны другие варианты идентификации кодов самодиагностики.
