5. Check if the "C1A24" is detected as the current malfunction in "Self Diagnostic Result" of "ICC".
Is "C1A24" detected as the current malfunction?
YES - Refer to C1A24.
NO - GO TO 2.
2.CHECK DTC REPRODUCE (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 Diagnostic Result" of "ICC".
Is "C1A24" detected as the current malfunction?
YES - Refer to C1A24.
NO - Refer to Intermittent Incident.




Diagnosis Procedure
1.CHECK SELF-DIAGNOSIS RESULTS
Check if "U1000" is detected other than "C1A24" in "Self Diagnostic Result" of "ICC".
Is "U1000" detected?
YES - Perform the CAN communication system inspection. Repair or replace the malfunctioning parts. Refer to CAN COMM Circuit.
NO - GO TO 2.
2.CHECK NP POSITION SWITCH SIGNAL
Check that "NP RANGE SW" operates normally in "DATA MONITOR" of "ICC".
Is the inspection result normal?
YES - GO TO 3.
NO - Replace the ICC sensor integrated unit. Refer to Exploded View.
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.
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 Testing and Inspection.
NO - Replace the ICC sensor integrated unit. Refer to Exploded View.
