DCA

C1A24 NP RANGE

Description

ICC sensor integrated unit judges the NP position status from the shift position signal and current gear position signal received from TCM via CAN communication.


DTC Logic


DTC DETECTION LOGIC






NOTE:
If DTC "C1A24" is detected along with DTC "U1000", first diagnose the DTC "U1000". Refer to "ICC SENSOR INTEGRATED UNIT : DTC Logic" DCA.

DTC CONFIRMATION PROCEDURE


1. PERFORM DTC CONFIRMATION PROCEDURE (1)

1.Start the engine.
2.Turn the DCA system ON.
3.Wait for approximately 5 minutes or more after shifting the selector lever to "P" position.
4.Perform "All DTC Reading" with CONSULT.
5.Check if the "C1A24" is detected as the current malfunction in self-diagnosis results of "ICC/ADAS".
Is "C1A24" detected as the current malfunction?
YES- Refer to "Diagnosis Procedure" .
NO- GO TO 2.

2. PERFORM DTC CONFIRMATION PROCEDURE (2)

1.Wait for approximately 5 minutes or more after shifting the selector lever to "N" position.
2.Perform "All DTC Reading".
3.Check if the "C1A24" is detected as the current malfunction in self-diagnosis results of "ICC/ADAS".
Is "C1A24" detected as the current malfunction?
YES- Refer to "Diagnosis Procedure" .
NO- Refer to "Intermittent Incident" Intermittent Incident.


Diagnosis Procedure


1. CHECK SELF-DIAGNOSIS RESULTS

Check if "U1000" is detected other than "C1A24" in "Self Diagnostic Result" of "ICC/ADAS".
Is "U1000" detected?
YES- Perform the CAN communication system inspection. Repair or replace the malfunctioning parts.
Refer to "ICC SENSOR INTEGRATED UNIT : DTC Logic" DCA.
NO- GO TO 2.

2. CHECK NP POSITION SWITCH SIGNAL

Check that "NP RANGE SW" operates normally in "DATA MONITOR" of "ICC/ADAS".
Is the inspection result normal?
YES- GO TO 3.
NO- GO TO 4.

3. CHECK TCM DATA MONITOR

Check that "SLCT LVR POSI" operates normally in "DATA MONITOR" of "TRANSMISSION".
Is the inspection result normal?
YES- Replace the ICC sensor integrated unit. Refer to "Exploded View" DCA.
NO- GO TO 4.

4. PERFORM TCM SELF-DIAGNOSIS

1.Perform "All DTC Reading".
2.Check if any DTC is detected in "Self Diagnostic Result" of "TRANSMISSION".
Is any DTC detected?
YES- Perform diagnosis on the detected DTC and repair or replace the malfunctioning parts. Refer to "DTC Index" Testing and Inspection.
NO- Replace the ICC sensor integrated unit. Refer to "Exploded View" DCA.
