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

Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

Has a problem been found?

	▶ Repair if necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Charging System Inspection" procedure.

Measure voltage between terminal (+) and (-) of battery maintaining ENG. RPM at 2,500RPM(idle) over 2 minutes.

Specification : Approx. 13 ~ 15 V

Is the measured voltage within specifications?

▶ Go to "Power Circuit Inspection" procedure.

▶ Check that the tension of drive velt, ENG RPM, fuse, terminal of battery, all terminals of alternator are in good condition and Check for damaged harness and poor connection between alternator and battery.

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

Measure voltage between battery power terminal of TPMS Module harness connector and chassis ground maintaining ENG. RPM at 2,500RPM(idle) over 2 minutes.

Specification : Approx. 13 ~ 15 V

Is the measured voltage within specifications?

▶ Go to "Ground Circuit Inspection" procedure.

▶ Check for open or blown fuse referring to "Circuit Diagram".

▶ Repair open or short in power circuit between battery and TPMS Module harness connector and then go to "Verification of vehicle Repair" procedure.

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

Specification : Approx. 1.0 Ω

Is the measured resistance within specifications?

▶ 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 open or contact resistance in ground harness.

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