Component Inspection

1.

Ignition "OFF"

2.

Disconnect Battery (-) terminal.

3.

Disconnect Clutch switch connector.

4.

Measure resistance between Pin No. 1 (Ground) and Pin No. 2 (Signal) of Clutch switch (Component Side).

Specification : Approx. below 1Ω (In case of ON the Gear R Switch) / Approx. ∞ Ω (In case of OFF the Gear R Switch)

5.

Is measure value within specification?

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

caution

In case of replacing HECU, perform following procedures.

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