Connect GDS to Data Link Connector(DLC).

ignition "ON"

Perform each "Valve" in "Actuation Test" with GDS.

Check for operation sound of valve while actuating each valve.

Does each valve operates properly?

▶ Fault might be intermittent and caused either by poor contact in connectors or wiring harness, or it has been repaired and control module memory is not cleared yet. Thoroughly check terminal of battery, 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" procedure.

▶ If no problems were found with the circuits or connectors, replace the HECU. Go to "Verification of Vehicle Repair" procedure.

In case of replacing HECU, perform following procedures.

1. Perform "Auto Detected Configuration Reset(ESP(ESC) Only)" for Varian Coding
