SYMPTOM DIAGNOSIS
DIFFERENCE IN APPEARANCE
DescriptionINFOID:0000000006256016
While the vehicle is stopped, the difference of vehicle height of right side and left side (between wheel center
and wheel arch) is 25 mm (0.98 in) or more.
Inspection ProcedureINFOID:0000000006256017
1.CHECK APPEARANCE
1. Visually check that the exterior parts (e.g. suspension spring) have no malfunctions.
2. Visually check tube and pipe for crush or oil leakage.
Is the check result normal?
YES >> GO TO 2.
NO >> Repair or replace damaged parts.
2.CHECK CLOGGING OF ORIFICE IN PPMU
1. Install an oil pressure gauge (SST: KV40108000) (A) to oil injec- tion jack.
CAUTION:
 Clean surrounding areas of oi l injection jack using steam
before starting oper ation, since there may be mud on it.
 Clean oil pressure gauge (special service tool:
KV40108000) jack with steam before use.
 Jack must be securely inserted until a click sound can be heard.
 Pressure reducing valve (B) of the oil pressure gauge
must be closed.
2. Loosen needle valves A and C of PPMU by approximately 2 rotations for check changes in vehicle height.
CAUTION:
Never loosen the needle valve more than required.
3. Tighten needle valve A and C of PPMU to the specified torque after the inspection.
Does the vehicle height change 10 mm (0.39 in) or more?
YES >> For detailed inspection of clogging of orifice in PPMU, refer to SCS-27, "
Work Procedure".
NO >> INSPECTION END

DTC DETECTION LOGIC
CAUTION:
If DTC C1755, C1756, C1757, or C1758 is detected al ong with, C1708, C1709, C1710, or C1711 first diag-
nose C1755, C1756, C1757, or C1758.
DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION
With CONSULT-III
1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Stop the vehicle.
3. Perform self-diagnosis for “AIR PRESSURE MONITOR”.
Is DTC
“C1755”, “C1756”, “C1757”, or “C1758 ” detected?
YES >> Proceed to WT-47, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000006225523
1.TRANSMITTER ID REGISTRATION
Perform transmitter ID registration. Refer to WT-29, "
Work Procedure".
Is transmitter ID registration completed?
YES >> GO TO 2.
NO >> Change the work location and perform ID registration again, then proceed to WT-60,
"DiagnosisProcedure".
2.CHECK TIRE PRESSURE SIGNAL
With CONSULT-III
1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Stop the vehicle.
3. Select “DATA MONITOR” for “AIR PRESSURE MONITOR” with CONSULT-III.
4. Within 5 minutes after vehicle stopped, check t hat the tire pressures match the standard value.
DTC Display Item Malfunction detected condition Possible causes
C1755 PR RECEIV COND FL The data signal from the front LH wheel transmitter cannot be
detected due to external electromagnetic interference for 10
minutes or more.
(DTC C1708 is displayed at the same time.)
External electromagnetic
interference
C1756 PR RECEIV COND FR
The data signal from the front RH wheel transmitter cannot be
detected due to external electromagnetic interference for 10
minutes or more.
(DTC C1709 is displayed at the same time.)
C1757 PR RECEIV COND RR The data signal from the rear RH wheel transmitter cannot be
detected due to external electromagnetic interference for 10
minutes or more.
(DTC C1710 is displayed at the same time.)
C1758 PR RECEIV COND RL The data signal from the rear LH wheel transmitter cannot be
detected due to external electromagnetic interference for 10
minutes or more.
(DTC C1711 is displayed at the same time.)
Monitor item Displayed value
AIR PRESS FL Approximately equal to the indication on tire gauge value for front LH tire
AIR PRESS FR Approximately equal to the indication on tire gauge value for front RH tire

ID REGISTRATION CANNOT BE COMPLETED
ID REGISTRATION CANNOT BE COMPLETED
DescriptionINFOID:0000000006225542
The ID of the transmitter installed in each wheel cannot be registered in the tire pressure monitoring system.
Inspect the transmitter or the tire pressure monitoring system circuit.
Diagnosis ProcedureINFOID:0000000006225543
1.TRANSMITTER WAKE-UP
Perform the transmitter wake-up. Refer to WT-28, "
Work Procedure".
Is the transmitter wake-up completed?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK TRANSMITTER ACTIVATION TOOL
Check transmitter activation tool.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace battery for transmitter activation tool, or repair or replace transmitter activation tool.
3.TRANSMITTER ID REGISTRATION
Perform transmitter ID registration. Refer to WT-29, "
Work Procedure".
Is transmitter ID registration completed?
YES >> GO TO 4.
NO >> Change the work location and perform ID registration again.
4.CHECK TIRE PRESSURE SIGNAL
With CONSULT-III
1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Stop the vehicle.
3. Select “DATA MONITOR” for “AIR PR ESSURE MONITOR” with CONSULT-III.
4. Within 5 minutes after vehicle stopped, check t hat the tire pressures match the standard value.
Is the inspection result normal?
YES >> INSPECTION END
