WARNING: This page is about a different car, the 2015 Hyundai Sonata. However, it is still accessible from the selected car via links, so may be relevant.
■ Short Check (to Ground)
- IG "OFF".
- Disconnect the Brake Pedal Travel sensor, AHB connectors.
- Measure resistance between PDT signal terminal of the Brake Pedal Travel sensor harness connector and chassis ground.
Specification: Approx. ∞ Ω
- Is the measured value within specifications?
YES
- Go to next procedure.
NO
- Repair short to ground in PDT signal circuit between the Brake Pedal Travel sensor harness connector and AHB harness connector and then, go to "VERIFICATION OF VEHICLE REPAIR "
■ Short Check (to Battery)
- Ignition "ON" & Engine "OFF".
- Disconnect the Brake Pedal Travel sensor, AHB connectors.
- Measure voltage between PDT signal terminal of the Brake Pedal Travel sensor harness connector and chassis ground.
Specification: Approx. 0 V
- Is the measured value within specifications?
YES
- Go to next procedure.
NO
- Repair short to battery in PDT signal circuit between the Brake Pedal Travel sensor harness connector and AHB ECU harness connector and then, go to "VERIFICATION OF VEHICLE REPAIR "
■ Open Check
- IG "ON".
- Disconnect the Brake Pedal Travel sensor, AHB connectors.
- Measure voltage between PDT signal terminal of the Brake Pedal Travel sensor harness connector and AHB ECU harness connector.
Specification: Approx. 0 Ω
- Is the measured value within specifications?
YES
- Substitute with a known-good Brake Pedal Travel sensor and check for proper operation. If problem is corrected, replace Brake Pedal Travel sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Repair open in PDF, PDT signal circuit between the Brake Pedal Travel sensor harness connector and AHB harness connector and then, go to "VERIFICATION OF VEHICLE REPAIR "
