1A-112 Engine General Information and Diagnosis:
Circuit Description
Battery voltage is supplied so that DTC memory, values for engine control learned by ECM, etc. are kept in ECM even
when the ignition switch is turned OFF.
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) With ignition switch OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC by using scan tool.
3) Run engine at idle speed for 1 min.
4) Check DTC.
DTC Troubleshooting
DTC P2101: Throttle Actuator Control Motor Circuit Range / Performance
S6RW0C1104065
Wiring Diagram
Refer to “DTC P0122 / P0123: Throttle / Pedal Position Sensor / Switch “A” Circuit Low / High”.
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC by using scan tool.
3) Keep the accelerator pedal at idle position for 2 sec.
4) Keep the accelerator pedal at fully depressed position for 2 sec.
5) Repeat Step 3) and 4) for 3 times.
6) Check DTC.
DTC detecting condition Trouble area
Backup power voltage of internal circuit is lower than specified
voltage for 5 sec.
(1 driving cycle detection logic) • Battery voltage supply circuit
• ECM
Step Action Yes No
1 Was “Engine and Emission Control System Check”
performed? Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2 Battery voltage supply circuit check
1) Turn ignition switch to OFF position.
2) Remove ECM from its bracket with ECM connectors
connected.
3) Measure ECM back-up power supply voltage between
ECM connector and vehicle body ground.
Is voltage 10 – 14 V?
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”. If OK, substitute a
known-good ECM and
recheck. ECM back-up power
supply circuit is open or
short.
DTC detecting condition Trouble area
Throttle actuator control circuit is higher than specified current or
temperature for 0.5 sec.
(1 driving cycle detection logic) • Throttle actuator control circuit
• Electric throttle body assembly
• ECM
