DTC DETECTION LOGIC
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition |
P2100 | ETC MOT PWR-B1 (Throttle actuator ″A″ control motor circuit/ open) | ECM detects a voltage of power source for throttle control motor is excessively low. |
P2103 | ETC MOT PWR-B1 (Throttle actuator ″A″ control motor circuit high) | ECM detect the throttle control motor relay is stuck ON. |
POSSIBLE CAUSE
DTC P2100
DTC P2103
FAIL-SAFE
ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx.
5 degrees) by the return spring.
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is more than 8 V.
Witch DTC is detected? P2100 >> GO TO 2.
P2103 >> GO TO 3.
2.PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P2100
Is DTC detected? YES >> Proceed to EC-431, "Diagnosis Procedure".
NO >> INSPECTION END
3.PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P2103
Is DTC detected? YES >> Proceed to EC-431, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL
Check the voltage between ECM harness connector and ground as per the following conditions.
Is the inspection result normal? YES >> GO TO 5.
NO >> GO TO 4.
4.CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK INTERMITTENT INCIDENT
