On Board Diagnosis Logic
EBS00QSP
This self-diagnosis has the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
DTC Confirmation Procedure
EBS00QSQ
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 8V at idle.
WITH CONSULT-II
1.
Turn ignition switch “ON”.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Start engine and let it idle for 1 second.
4.
If DTC is detected, go to
EC-502, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

Sensor power supply circuit
short
ECM detects a voltage of power source
for sensor is excessively low or high.
●
Harness or connectors
(The TP sensor 1 and 2 circuit is shorted.)
●
Electric throttle control actuator
(TP sensor 1 and 2)
Engine operation condition in fail-safe mode
ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return
spring.
