DTC DETECTION LOGIC
NOTE:
• If DTC P1217 is displayed with DTC UXXXX, first perform the tr ouble diagnosis for DTC UXXXX.
• If DTC P1217 is displayed with DTC P0607, first pe rform the trouble diagnosis for DTC P0607. Refer
to EC-884, "DTC Logic"
.
If the cooling fan or another component in the coo ling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnorma lly high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be su re to replace the coolant. Refer to CO-35, "System Inspection"
.
Also, replace the engine oil. Refer to MA-27, "ENGINE OIL : Changing Engine Oil"
.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-12, "FOR USA AND CANADA : Engine Cool-
ant Mixture Ratio".
2. After refilling coolant, run engine to en sure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-892, "Component Function Check"
.
NOTE:
Use component function check to check the overall functi on of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-893, "Diagnosis Procedure"
.
Component Function CheckINFOID:0000000009462750
1.PERFORM COMPONENT FUNCTION CHECK-I
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.

HYDRAULIC PUMP ELECTRIC POWER STEE RING SYSTEM : Protection Function
INFOID:0000000009460346
• When the steering wheel is operated repeatedly or turned all the way for a long period during parking or low
speed driving, the function of the hydraulic pump elec tric power steering system becomes limited to prevent
the system from overheating. Cont inued operation of the steering wheel will cause the hydraulic pump elec-
tric power steering system to stop and the hydraulic pum p electric power steering system warning lamp may
come ON. In this case, the steering wheel operation temporarily becomes hard. This is not a malfunction.
When the engine is turned OFF (ignition switch OFF) and steering operation is stopped for a while, the tem-
perature of the hydraulic pump electric power steer ing system decreases and the steering operation returns
to normal after restarting the engine.
• Then, the hydraulic pump electric power steering syste m warning lamp turns OFF. If the system is OFF
under the protection state, the hydraulic pump electr ic power steering system warning lamp turns ON to
warn that the system is in the manual steering state. (This is not a system malfunction.) In addition, the fol-
lowing DTC remains to distinguish from malfunction.
C1608 Manual steering state
U1000 Normal control
NOTE:
If the cause is in a different ECU, the state changes to fixed steering assist force.
DTC Fail-safe condition

C160A The system temporarily enters the manual steering state. (This is not a hydraulic pump electric
power steering system malfunction.)

Fail-safeINFOID:0000000009460349
When an error occurs in the hydraulic pump electric pow er steering system, fail-safe brings the system to a
halt (manual steering) or restricted (constant steering assi st level) state. When the system is in a halt state,
fail-safe turns ON the hydraulic pump electric power steer ing warning lamp to warn the driver that the hydrau-
lic pump electric power steering system is in the manual steering state.
Protection FunctionINFOID:0000000009460350
• When the steering wheel is operated repeatedly or turned all the way for a long period during parking or low
speed driving, the function of the hydraulic pump elec tric power steering system becomes limited to prevent
the system from overheating. If the steering wheel is operated further more, the hydraulic pump electric
power steering system stops and the hydraulic pump el ectric power steering system warning lamp may be
turned ON. In this case, the steering wheel operation temporarily becomes hard. This is not a malfunction.
When the engine is turned OFF (ignition switch OFF) and steering operation is stopped for a while, the tem-
perature of the hydraulic pump electric power steeri ng system decreases and the steering operation returns
to normal after restarting the engine.
