C1F06

C1F06 CAN CIRCUIT2

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






NOTE:
If DTC "C1F06" 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.Start the engine.
2.Turn the DCA system ON.
3.Perform "All DTC Reading" with CONSULT.
4.Check if the "C1F06" is detected as the current malfunction in self-diagnosis results of "ACCELE PEDAL
ACT".
Is "C1F06" 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 "C1F06" in "Self Diagnostic Result" of "ACCELE PEDAL ACT".
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. REPLACE ICC SENSOR INTEGRATED UNIT

1.Turn the ignition switch OFF.
2.Replace the ICC sensor integrated unit. Refer to "Exploded View" DCA.
3.Erases All self-diagnosis results.
4.Perform "All DTC Reading" again.
5.Check if the "C1F06" is detected in self-diagnosis results of "ACCELE PEDAL ACT".
Is "C1F06" detected?
YES- Replace the accelerator pedal assembly.
NO- INSPECTION END


Special Repair Requirement


DESCRIPTION

- Removal and installation of ICC sensor integrated unit
- Replacement of ICC sensor integrated unit
Check the operation after performing the accelerator pedal released position learning when the following operation is performed.
- Disconnection and connection of accelerator pedal position sensor connector
- Replace accelerator pedal assembly

SPECIAL REPAIR REQUIREMENT


1. CHECK CONTROL UNIT REPLACED, REMOVED AND/OR INSTALLED

Perform the adjustment work after the replacement or removal and installation of ICC sensor integrated unit, replacement of accelerator pedal assembly, or disconnection or connection of accelerator pedal position sensor connector.
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 "LASER BEAM AIMING ADJUSTMENT : Description" Description.
- GO TO 4.

3. ACCELERATOR PEDAL RELEASED POSITION LEARNING

Perform the Accelerator Pedal Released Position Learning. Refer to "ACCELERATOR PEDAL RELEASED POSITION LEARNING : Description" 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 "ACTION TEST : Description" Description(Distance Control Assist) for action test.)
2.Check that the DCA system is normal.
- WORK END
