POSSIBLE CAUSE
-
Harness or connectors (Throttle control motor circuit is open or shorted.)
-
Electric throttle control actuator
FAIL-SAFE
Engine Control System
| Fail safe mode | Nissan Ariya Vehicle behavior | |
|---|---|---|
| Device fix mode |
|
|
| Electric throttle control cancel mode | ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring. | |
Stop/Start System
When a DTC is detected, the stop/start indicator lamp blinks slowly and the stop/start system operation is prohibited.
When ECM detects error while operating the stop/start system, ECM restarts the engine.
DTC Confirmation Procedure
CHECK DTC PRIORITY
If DTC P2101 is displayed with DTC P2100 or P2119, first perform the trouble diagnosis for DTC P2100 or P2119.
Is applicable DTC detected?
YES>>Perform diagnosis of applicable. Refer to DTC Index.
NO>>GO TO 2.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
-
Turn ignition switch OFF and wait at least 10 seconds.
-
Turn ignition switch ON.
-
Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V when engine is running.
>>
GO TO 3.
PERFORM DTC CONFIRMATION PROCEDURE
-
Turn ignition switch ON and wait at least 2 seconds.
-
Start engine and let it idle for 5 seconds.
-
Check DTC.
Is DTC detected?
YES>>Proceed to DTC Diagnosis Procedure.
NO-1>>To check malfunction symptom before repair: Refer to Intermittent Incident.
NO-2>>Confirmation after repair: INSPECTION END
DTC Diagnosis Procedure
CHECK DTC PRIORITY
If DTC P2101 is displayed with DTC P2100 or P2119, first perform the trouble diagnosis for DTC P2100 or P2119.

CHECK THROTTLE CONTROL MOTOR INPUT SIGNAL
Check the voltage between ECM harness connector terminals as per the following conditions.
| ECM | Condition |
Voltage (Approx.) | |||
|---|---|---|---|---|---|
| + | − | ||||
| Connector | Terminal | Connector | Terminal | ||
| F72 | 24 | E21 | 160 | Ignition switch: OFF | 0 V |
| Ignition switch: ON | Battery voltage | ||||
Is the inspection result normal?
YES>>GO TO 5.
NO>>GO TO 3.
