Pipe Assembly
POWER ASSISTED SYSTEM (POWER STEERING)
C: INSPECTION
Check all disassembled parts for wear, damage or other problems. Repair or replace the defective parts as
necessary.
CAUTION:
Although the surface layer materials of rubber hoses have excellent weathering resistance, heat re-
sistance and resistance for low temperature brittleness, they are likely to be damaged chemically by
brake fluid, battery electrolyte, engine oil and automatic transmission fluid and their service lives are
to be very shortened. Wipe off hoses immediately if any of these come into contact with the hoses.
Since resistances for heat or low temperature brittleness are gradually declining according to time
accumulation of hot or cold conditions for the hoses and their service lives are shortening accord-
ingly, it is necessary to perform careful inspection frequently when the vehicle is used in hot weather
areas, cold weather areas and a driving condition in which many steering operations are required in
short time.
Particularly continuous work of relief valve over 5 seconds causes to reduce service lives of the hos-
es, the oil pump, the fluid, etc. due to over heat.

Tire Pressure Warning Light/Trouble Indicator Light Illumination Pattern (DTC)
TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
1) When the tire pressure warning light does not illuminate in accordance with this illumination pattern, there
must be an electrical malfunction.
2) When tire pressure warning light does not go off, check the tire pressure monitoring control module/warn-
ing light circuit and the combination meter circuit.
(DTC).>
NOTE:
If the problem is fixed while driving at approximately 40 km/h (25 MPH) after the tire pressure warning light
blinks/lights, the warning light goes out and the tire pressure monitor system operates normally. (If there is
a decrease in tire pressure, or malfunction of the system, the past malfunctions are displayed.)
B: TIRE PRESSURE WARNING LIGHT DOES NOT ILLUMINATE
DETECTING CONDITION:
•Defective combination meter
•Defective harness
TROUBLE SYMPTOM:
When the ignition switch is turned to ON (engine OFF), the tire pressure warning light does not come on (for
approximately 2 seconds).
