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 Yes Go to applicable DTC troubleshooting procedure.
(See DTC TABLE [MZR 2.5] .)
(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 DSC 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 the ABS wheel-speed sensors, related wiring harnesses, and installation.
(See FRONT ABS WHEEL-SPEED SENSOR INSPECTION .)
(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 OFF (LOCK).
  • 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.
