1.

Many malfunctions in the electrical system are caused by poor connection. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

2.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration,or damage.

3.

Has a problem been found?

	▶ Repair if necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to Next procedure.

1.

Ignition "OFF"

2.

Disconnect TPMS Module connector.

3.

Engine "ON".

4.

Measure voltage between battery power terminal of TPMS ECU(Module) harness connector and chassis ground.

Specification : Approx. 13 ~ 15 V

5.

Is the measured voltage within specifications?

▶ Go to Next procedure.

▶ Check for short in harness or blown fuse.

▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.

1.

Ignition "OFF"

2.

Disconnect TPMS Module connector.

3.

Measure resistance between ground terminal of TPMS Module harness connector and chassis ground.

Specification : Approx. 1.0 Ω

4.

Is the measured resistance within specifications?

▶ Fault is intermittent caused by poor contact in the sensor’s and/or Control module’s connector or was repaired and Control module’s memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

▶ Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

▶ Substitute with a known-good TPMS Module and check for proper operation.

If the problem is corrected,replace TPMS Module and then go to "Verification of Vehicle Repair" procedure.

▶ After replacing with a known-good TPMS Module, you must do the 'Vehicle Name Writing', 'VIN Writing' and 'Register Sensor' at the "Vehicle S/W Management" mode by using GDS and GDS TPMS.

▶ Check for short in harness.

▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
