DEVIATION BETWEEN DRIVING DIAGNOSTIC SCORE AND DRIVE FEEL [INTELLIGENT DRIVE MASTER (i-DM)]

id0903k6017800

Description

• Frequency of the white lamp display is high even though the vehicle is driven on level straightaway.

• The driving diagnostic score according to a stage is not displayed.

• The driving diagnostic score is bad compared with another vehicle of the same model.

Possible Cause

• Connectivity master unit (CMU) malfunction

• Instrument cluster malfunction

White lamp deviation due to the pedal operation

• The PCM detects a malfunction and the vehicle driving condition is in fail-safe.

• Accelerator pedal position sensor signal error

― Accelerator pedal position sensor malfunction

― Accelerator pedal malfunction

― Wiring harness malfunction between accelerator pedal position sensor and PCM

• Vehicle speed signal error

― ABS wheel speed sensor malfunction (improper installation, malfunction)

― ABS wheel-speed sensor rotor loss

― Tire malfunction (pressure adjustment malfunction, irregular tire diameter)

• Engine malfunction (engine malfunction increases acceleration pedal depression)

― Abnormal acceleration

― Hesitation during acceleration

White lamp deviation due to the steering operation

• Steering angle (estimated absolute steering angle) signal error

― EPS control module malfunction

• Vehicle speed signal error

― ABS wheel speed sensor malfunction (improper installation, malfunction)

― ABS wheel-speed sensor rotor loss

― Tire malfunction (pressure adjustment malfunction, irregular tire diameter)

VERIFY DTCs FOR RELATED MODULES

•  Using the M-MDS, verify DTCs for PCM, DSC HU/CM, EPS control module, instrument cluster and connectivity master unit (CMU).
(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 1.3, SKYACTIV-G 1.5)].)

(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 1.5)].)

(See DTC INSPECTION [DSC HU/CM])

(See DTC INSPECTION [EPS CONTROL MODULE])

(See DTC INSPECTION [INSTRUMENT CLUSTER])

(See DTC INSPECTION [CONNECTIVITY MASTER UNIT])

•  Can DTCs be verified?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [PCM (SKYACTIV-G 1.3, SKYACTIV-G 1.5)])

(See DTC TABLE [PCM (SKYACTIV-D 1.5)])

(See DTC TABLE [DSC HU/CM])

(See DTC TABLE [EPS CONTROL MODULE])

(See DTC TABLE [INSTRUMENT CLUSTER])

(See DTC TABLE [CONNECTIVITY MASTER UNIT])

No

•  System is normal.
If the vehicle is normal, refer to INTELLIGENT DRIVE MASTER (i-DM) for new vehicle instruction, and explain the contents of the driving operation determination and display to the customer to have them understand that there is no problem in the system.

•  Symptom troubleshooting is completed.
