Motor Driven Power Steering Diagnosis: Specifications Kia Rio III

Specification

Bat. Voltage	IG Key ON	ENG. ON
Bat. Voltage	Approx. 11.8 [V]~12.5 [V]	Approx. 12.5 [V] ~ 14.5 [V]

Scheme 64: Diagnostic Circuit Diagram

Scheme 65: Monitor Scantool Data

Connect scantool to Data Link Connector(DLC).
Start engine and turn the headlight and the heatwire on.
Monitor the "SUPPLY VOLTAGE" parameter on the scantool.
Maintaining ENGINE at 2, 500 RPM (idle) over 2 minutes. Specification: Approx. 12.5V~14.5V
Is parameter within specifications? YES Fault is intermittent and caused either by poor contact in connectors or wiring harness, or it has been repaired and EPS CM memory is not cleared yet. Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage. Repair or replace as necessary and then go to " «VERIFICATION OF VEHICLE REPAIR»(ref-536168-S34235011132013031400000) " procedure. NO Go to " «W/HARNESS INSPECTION»(ref-536168-S34552147252013031400000) " procedure.
