DTC P1217 ENGINE OVER TEMPERATURE
PFP:00000
System DescriptionEBS00KJ1
NOTE:
If DTC P1217 is displayed with DTC U1000, U1001, first perform the trouble diagnosis for DTC U1000,
U1001. Refer to EC-492, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
COOLING FAN CONTROL
*1: The ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: These signals are sent to the ECM through CAN communication line.
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, refrigerant
pressure, and air conditioner ON signal. The control system has 2-step control [ON/OFF].
The ECM sends a cooling fan control signal to the smart entrance control unit through CAN communication
line, and the smart entrance control unit controls cooling fan relay.

DescriptionEBS00KLE
NOTE:
If DTC U1000 or U1001 is displayed, first perform the trouble diagnosis for DTC U1000, U1001. Refer to
EC-492, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
The vehicle speed signal is sent from vehicle speed sensor (models with ABS) or ABS actuator and electric
unit (control unit) (models with ABS) to combination meter. The combination meter then sends a signal to the
ECM through CAN communication line.
Diagnostic ProcedureEBS00KLF
1.CHECK VEHICLE SPEED SIGNAL OVERALL FUNCTION
With CONSULT-II
1. Lift up the vehicle.
2. Start engine.
3. Select “VHCL SPEED SE” in “DATA MONITOR” mode with
CONSULT-II.
4. Make sure that “VHCL SPEED SE” indication exceeds 10 km/h
(6 MPH) when rotating wheels with suitable gear position.
Without CONSULT-II
1. Lift up the vehicle.
2. Start engine.
3. Read vehicle speed with combination meter.
Make sure that vehicle speed indication exceeds 10 km/h (6 MPH) when rotating wheels with suitable
gear position.
OK or NG
OK >>INSPECTION END
NG >> GO TO 2.
2.CHECK DTC WITH VEHICLE SPEED SONSOR (MODELS WITHOUT ABS) OR ABS ACTUATOR AND
ELECTRIC UNIT (CONTROL UNIT) (MODELS WITH ABS)
Refer to EL-123 (models without ABS) or EL-124 (models with ABS).
OK or NG
OK >> GO TO 2.
NG >> Repair or replace.
3.CHECK COMBINATION METER
Check combination meter function.
Refer to EL-112.
>>INSPECTION END
SEF196Y

3 CHECK IDLE SPEED
With CONSULT-II
1. Select “CKPS·RPM (TDC)” in “DATA MONITOR” mode with CONSULT-II.
2. Read idle speed.
SEF817Y
Without CONSULT-II
Check idle speed.

4 CHECK FOR INTAKE AIR LEAK
Listen for an intake air leak after the mass air flow sensor.
OK or NG
OK GO TO 5.
NG Repair or replace.
5 BLEED AIR FROM FUEL SYSTEM
1. Stop engine.
2. Use priming pump to bleed air from fuel system. Refer to “AIR BLEEDING”, EC-32.

Malfunction Indicator (MI)ECS007NR
1. The malfunction indicator lamp will light up when the ignition
switch is turned ON without the engine running. This is for
checking the lamp.
●If the malfunction indicator does not light up, refer to EC-397
or EC-715 .
(Or see MI & CONSULT-II in EC section. Refer to EC-49
, EC-
87 .
2. When the engine is started, the malfunction indicator should
turned OFF.
If the lamp remains ON, the on board diagnostic system has
detected an emission-related (EURO-OBD) malfunction. For
detail, refer to EC-36.
CONSULT-IIECS007NS
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” AT- 4 1 , place check marks for
results on the “DIAGNOSTIC WORKSHEET”, AT- 5 7
. Reference pages are provided following the items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid valve).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoid valves, sensors, etc.) may be malfunctioning. Check
mechanical parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)
1. Turn on CONSULT-II and touch “ENGINE” for EURO-OBD
detected items or touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground cir-
cuit. Refer to AT- 1 0 6 , "
TCM Terminals and Reference Value" . If
result is NG, refer to EL-11, "POWER SUPPLY ROUTING".
2. Touch “SELF DIAGNOSIS”.
Display shows malfunction experienced since the last erasing
operation.
CONSULT-II performs “real time diagnosis”.
Also, any malfunction detected while in this mode will be dis-
played at real time.
