C1A36

C1A36 ACCELERATOR PEDAL ACTUATOR CAN COMM





Description
- ITS communication is a multiplex communication system. This enables the system to transmit and receive large quantities of data at high speed by connecting ICC sensor integrated unit, brake booster control unit, and accelerator pedal actuator with 2 communication lines.
- ITS communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.




DTC Logic

DTC DETECTION LOGIC

DTC DETECTION LOGIC:

NOTE:
If DTC "C1A36" is detected along with DTC "U1000", first diagnose the DTC "U1000". Refer to DCA DCA DCA DCA.

DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Start the engine.
2. Turn the DCA switch ON.
3. Perform "All DTC Reading" with CONSULT-III.
4. Check if the "C1A36" is detected as the current malfunction in self-diagnosis results of "ICC".
Is "C1A36" detected as the current malfunction?
YES - Refer to C1A36.
NO - Refer to Intermittent Incident.




Diagnosis Procedure
1.CHECK ICC SENSOR INTEGRATED UNIT SELF-DIAGNOSIS RESULTS
Check if "U1000" is detected other than "C1A36" in "Self Diagnostic Result" of "ICC".
Is "U1000" detected?
YES - Perform the CAN communication system inspection. Repair or replace the malfunctioning parts. Refer to DCA.
NO - GO TO 2.
2.CHECK ACCELERATOR PEDAL ACTUATOR SELF-DIAGNOSIS RESULTS
Check if the DTC is detected in "Self Diagnostic Result" of "ACCELE PEDAL ACT".
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.




Special Repair Requirement

DESCRIPTION

Which is replaced, removed or installed?
ICC sensor integrated unit-GO TO 2.
Accelerator pedal assembly-GO TO 3.
2.LASER BEAM AIMING ADJUSTMENT OF ICC SENSOR INTEGRATED UNIT
Adjust the laser beam aiming of the ICC sensor integrated unit. Refer to ICC (Full Speed Range) ICC (Full Speed Range) Description.
- GO TO 4.
3.ACCELERATOR PEDAL RELEASED POSITION LEARNING
Perform the Accelerator Pedal Released Position Learning. Refer to Special Repair Requirement Description Special Repair Requirement Description Special Repair Requirement Description.
- GO TO 4.
4.CHECK DCA SYSTEM
1. Erase the self-diagnosis results, and then perform "All DTC Reading" again after performing the action test. (Refer to DCA for action test.)
2. Check that the DCA system is normal.
- WORK END
