NO. 8 SPEEDOMETER INDICATION IS DEFECTIVE [INSTRUMENT CLUSTER]

id0903d5826300

8

Speedometer indication is defective
POSSIBLE CAUSE
•  ABS HU/CM malfunction
•  DSC HU/CM malfunction
•  PCM malfunction
•  Instrument cluster malfunction
•  Connector or pin malfunction
•  Short circuit in wiring harness between CAN-L, CAN-H and ground
•  Open circuit in CAN wiring harness (CAN-L, CAN-H)
•  CAN wiring harness (CAN-L, CAN-H) short each other

Diagnostic procedure

STEP

INSPECTION

RESULT

ACTION
1
•  Start the engine, and drive the vehicle.
―  Does the speedometer needle move smoothly?
―  Does the speedometer needle indicate correct speed?
Yes
Troubleshooting completed. (The system is normal.)
No
Go to the next step.
2
•  Reactive the DTC of instrument cluster, PCM, ABS HU/CM and/or DSC HU/CM using M-MDS.
•  Is the DTC detected?
Yes
Go to applicable DTC troubleshooting procedure.
(See DTC TABLE [INSTRUMENT CLUSTER].)
(See DTC TABLE [MZR 2.0 DISI i-stop].)
(See DTC TABLE [MZR 1.5, MZR 1.6].)
(See DTC TABLE [MZR-CD 2.2].)
(See DTC TABLE [MZ-CD 1.6].)
(See DTC TABLE [MZR 2.0, MZR 2.5].)
(See DTC TABLE [MZR 2.3 DISI Turbo].)
(See DTC TABLE [SKYACTIV-G 2.0].)
(See ON-BOARD DIAGNOSIS [ABS].)
(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
No
Go to the next step.
3
•  Verify that the speedometer needle moves using the M-MDS instrument cluster simulation function SPDMTR.
•  Does the speedometer needle move according to simulation function?
Yes
Go to the next step.
No
Replace the instrument cluster.
(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
4
•  Monitor the following PIDs for the ABS HU/CM or the DSC HU/CM using the M-MDS: WSPD_LF, WSPD_LR, WSPD_RF, WSPD_RR
Caution
•  To prevent an accident, work with two people when the vehicle is being driven. (One drives the vehicle and the other operates the M-MDS.)
•  Drive the vehicle and compare the M-MDS monitored value with the speedometer indication.
•  Does the M-MDS monitored value correspond to the speedometer indication?
Yes
Go to the next step.
No
Inspect for ABS wheel speed sensors, related wiring harnesses, and installation.
(See FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)
(See REAR ABS WHEEL-SPEED SENSOR INSPECTION.)
5
•  Disconnect the negative battery cable.
•  Measure the resistance between the DLC-2 terminals F and E.
•  Is the resistance below 60 ohms?
Yes
Go to the next step.
No
Go to Step 7.
6
•  Disconnect the negative battery cable.
•  Inspect the DLC-2 terminals F and E for short to power supply or ground.
•  Is there any malfunction?
Yes
Inspect the wiring harness and CAN system-related module.
Repair or replace the malfunctioning part.
No
Replace the instrument cluster.
7
•  Switch the ignition to off.
•  Inspect the instrument cluster connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Are the terminals normal?
Yes
Go to the next step.
No
Repair or replace the terminal.
8
•  Disconnect the negative battery cable.
•  Measure the resistance between the instrument cluster connector terminals 2B and 2D.
•  Is the resistance 114—126 ohms?
Yes
Inspect the wiring harness and CAN system-related module.
Repair or replace the malfunctioning part.
No
Replace the instrument cluster.
