7

Speedometer indication is defective

POSSIBLE CAUSE

•  ABS HU/CM stores DTC •  DSC HU/CM stores DTC •  PCM stores DTC •  TCM stores DTC •  ABS HU/CM malfunction •  DSC HU/CM malfunction •  PCM malfunction •  TCM malfunction •  Instrument cluster malfunction •  Poor connection of instrument cluster connector, terminal damage •  Poor connection of ABS HU/CM or DSC HU/CM connector, terminal damage •  Poor connection of PCM connector, terminal damage •  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		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	•  Retrieve the DTCs related to the PCM, TCM, ABS CM and DSC CM using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [L8, LF, L5].) (See ON-BOARD DIAGNOSTIC TEST [MZR-CD (RF Turbo)].) (See ON-BOARD DIAGNOSTIC TEST [MZR-CD 2.2].) (See ON-BOARD DIAGNOSIS [ABS].) (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) (See AUTOMATIC TRANSAXLE ON-BOARD DIAGNOSTIC FUNCTION [FS5A-EL].) •  Is there any DTC retrieved?	Yes	Go to the applicable troubleshooting procedure. (See DTC TABLE [L8, LF, L5].) (See DTC TABLE [MZR-CD (RF Turbo)].) (See DTC TABLE [MZR-CD 2.2].) (See ON-BOARD DIAGNOSIS [ABS].) (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) (See DTC TABLE [FS5A-EL].)
		No	Go to the next step.
3	•  Start the engine. •  Inspect the tachometer and water temperature gauge indications. •  Do the tachometer and water temperature gauge function properly?	Yes	Go to the next step.
		No	Go to Step 5.
4	•  Inspect that the speedometer indication when the following commands are send to the instrument cluster using the M-MDS active command modes SPDMTR. (See ACTIVE COMMAND MODES TABLE [INSTRUMENT CLUSTER].) Note •  The simulation activation values (%) are which 300 km/h is assumed to be 100 % (3 km/h = 1 %). ―  Activate 10 %: 30 km/h indicates ―  Activate 20 %: 60 km/h indicates ―  Activate 30 %: 90 km/h indicates •  Does the tachometer move according to active command modes?	Yes	Verify that the PCM, TCM, ABS HU/CM and DSC HU/CM are connected securely. If the PCM, TCM, ABS HU/CM or DSC HU/CM is poorly connected: Connect the suspected connector securely. If a malfunction is in the PCM, TCM, ABS HU/CM or DSC HU/CM side connector: Replace the suspected control module (See PCM REMOVAL/INSTALLATION [L8, LF, L5].) (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].) (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].) (See TCM REMOVAL/INSTALLATION [FS5A-EL].) (See ABS HU/CM REMOVAL/INSTALLATION.) (See PARKING BRAKE LEVER REMOVAL/INSTALLATION.) (See DSC HU/CM REMOVAL/INSTALLATION) If a malfunction is in the vehicle side connector: Repair or replace the malfunctioning part.
		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
5	•  Retrieve the DTC related to the instrument cluster using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) •  Is there any DTC retrieved?	Yes	Go to applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER].)
		No	Go to the next step.
6	•  Disconnect the negative battery cable. •  Measure the resistance between the DLC-2 terminals F and E. •  Is the resistance 54—66 ohms?	Yes	Go to the next step.
		No	Go to Step 7.
7	•  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. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
8	•  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.
9	•  Disconnect the negative battery cable. •  Measure the resistance between the instrument cluster connector terminals 2X and 2W. •  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. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
