2005 Hyundai Santa Fe GLS, 2.7 D, AWDSECTION Signal Circuit Inspection

[With ABS]

  1. Check for open in circuit
    1. Ignition "OFF".
    2. Disconnect ECM and ABS or ESP Control Module connectors.
    3. Measure resistance between terminals 22 of the ECM harness connector and 3 of the ABS Control Module harness connector (W/ABS)

      Specification: Approx. 0Ω

    4. Is resistance within the specification?

      YES 

      • Go to next step.

      NO 

  2. Check for short to ground in circuit.
    1. Measure resistance between terminal 22 of the ECM harness connector and chassis ground.

      Specification: Infinite

    2. Is resistance within the specification?

      YES 

      • Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO 

    [Without ABS system] 

  3. Check for open in circuit.
    1. Ignition "OFF".
    2. Disconnect ECM and wheel speed sensor (front right) harness connector.
    3. Measure resistance between wheel speed sensor harness connector and ECM harness connector.

      Specification: Approx. 0Ω

      [W/O 4WD]

      • Terminal 1 (sensor) & Terminal 38 (ECM)
      • Terminal 2 (sensor) & Terminal 39 (ECM)

    4. Is resistance within the specification?

      YES 

      • Go to next step.

      NO 

  4. Check for short to ground in circuit.
    1. Measure resistance between terminal 38 of the ECM harness connector and chassis ground.
    2. Measure resistance between terminal 39 of the ECM harness connector and chassis ground.

      Specification: Infinite

    3. Is resistance within the specification?

      YES 

      • Check wheel speed sensor (FR) as follow:
        • Gap between ABS sensor and trigger wheel (Air gap: 0.3~0.9 mm (0.011 ~ 0.035 in))
        • Trigger wheel condition.
        • Sensor resistance: Approx. 1,275~1,495 Ω at 20°C (68°F)
      • Replace wheel speed sensor as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
