DIAGNOSTIC PROCEDURE

STEP INSPECTION ACTION
1 INSPECT ABS WHEEL-SPEED SENSOR FOR SHORT TO GROUND
  • Switch the ignition to off.
  • Disconnect the DSC HU/CM connectors.
  • Inspect for continuity between the following DSC HU/CM connector terminals (vehicle harness-side) and body ground:
    • RF ABS wheel-speed sensor (+): F
    • RF ABS wheel-speed sensor (-): C
    • LF ABS wheel-speed sensor (+): AG
    • LF ABS wheel-speed sensor (-): AJ
    • RR ABS wheel-speed sensor (+): AA
    • RR ABS wheel-speed sensor (-): X
    • LR ABS wheel-speed sensor (+): L
    • LR ABS wheel-speed sensor (-): O
  • Is there continuity?
Yes Go to the next step.
No Go to Step 3.
2 INSPECT ABS WHEEL-SPEED SENSOR WIRING HARNESS FOR SHORT TO GROUND
  • Disconnect the ABS wheel-speed sensor connectors.
  • Inspect for continuity between the following DSC HU/CM connector terminals (vehicle harness-side) and body ground:
    • RF ABS wheel-speed sensor (+): F
    • RF ABS wheel-speed sensor (-): C
    • LF ABS wheel-speed sensor (+): AG
    • LF ABS wheel-speed sensor (-): AJ
    • RR ABS wheel-speed sensor (+): AA
    • RR ABS wheel-speed sensor (-): X
    • LR ABS wheel-speed sensor (+): L
    • LR ABS wheel-speed sensor (-): O
  • Is there continuity?
Yes Repair or replace the wiring harness, then go to Step 5.
No Replace the ABS wheel-speed sensor, then go to Step 5.

3 INSPECT FOR OPEN CIRCUIT IN ABS WHEEL-SPEED SENSOR WIRING HARNESS
  • Inspect for continuity between the DSC HU/CM connectors (vehicle harness-side) and the following vehicle harness-side connector terminals of the ABS wheel-speed sensors:
    • RF ABS wheel-speed sensor (+): F-A
    • RF ABS wheel-speed sensor (-): C-B
    • LF ABS wheel-speed sensor (+): AG-A
    • LF ABS wheel-speed sensor (-): AJ-B
    • RR ABS wheel-speed sensor (+): AA-B
    • RR ABS wheel-speed sensor (-): X-D
    • LR ABS wheel-speed sensor (+): L-B
    • LR ABS wheel-speed sensor (-): O-D
  • Is there continuity?
Yes Go to the next step.
No Repair or replace the wiring harness, then go to the next step.
4 INSPECT ABS WHEEL-SPEED SENSOR WIRING HARNESS FOR SHORT TO POWER SUPPLY
  • Inspect for voltage between the following DSC HU/CM connector terminals (vehicle harness-side) and body ground:
    • RF ABS wheel-speed sensor (+): F
    • RF ABS wheel-speed sensor (-): C
    • LF ABS wheel-speed sensor (+): AG
    • LF ABS wheel-speed sensor (-): AJ
    • RR ABS wheel-speed sensor (+): AA
    • RR ABS wheel-speed sensor (-): X
    • LR ABS wheel-speed sensor (+): L
    • LR ABS wheel-speed sensor (-): O
  • Is the voltage 1 V or less?
Yes Go to the next step.
No Repair or replace the wiring harness, then go to the next step.
5 VERIFY THAT THE SAME DTC IS NOT PRESENT Yes Repeat the inspection from Step 1.
If the malfunction recurs, replace the DSC HU/CM, then go to the next step.
(See DSC HU/CM REMOVAL/INSTALLATION .)
No Go to the next step.
6 VERIFY THAT NO OTHER DTCS ARE PRESENT
  • Are any other DTCs output?
Yes Go to the applicable DTC inspection.
(See DTC TABLE [DYNAMIC STABILITY CONTROL (DSC)] .)
No DTC troubleshooting completed.
