Many malfunctions in the electrical system are caused by poor harness and terminals.

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 as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Power Circuit Inspection" as below.

IG key "OFF" and engine "OFF".

Disconnect AHS CM harness connector and "ACTIVE HOOD LIFT ACTUATOR RH" harness connector.

Measure the resistance between "Actuator On RH" terminal of AHS CM harness connector and power terminal of "ACTIVE HOOD LIFT ACTUATOR RH" harness connector.

Is the measured resistance within the specification?

	▶ Go to "Check short to battery in power circuit" as below.
	▶ Repair open in "ACTIVE HOOD LIFT ACTUATOR RH" power circuit and go to "Verification of Vehicle Repair".

IG key "OFF" and engine "OFF".

Disconnect AHS CM harness connector and "ACTIVE HOOD LIFT ACTUATOR RH" harness connector.

IG key "ON" and engine "OFF".

Measure the voltage between power terminal of "ACTIVE HOOD LIFT ACTUATOR RH" harness connector and chassis ground.

Is the measured voltage within the specification?

	▶ Go to "Check short to ground in power circuit" as below.
	▶ Repair short to battery in "ACTIVE HOOD LIFT ACTUATOR RH" power circuit and go to "Verification of Vehicle Repair".

IG key "OFF" and engine "OFF".

Disconnect AHS CM harness connector and "ACTIVE HOOD LIFT ACTUATOR RH" harness connector.

Measure the resistance between power terminal of "ACTIVE HOOD LIFT ACTUATOR RH" harness connector and chassis ground.

Is the measured resistance within the specification?

	▶ Go to "Ground Circuit Inspection" procedure.
	▶ Repair short to ground in "ACTIVE HOOD LIFT ACTUATOR RH" power circuit and go to "Verification of Vehicle Repair".

IG key "OFF" and engine "OFF".

Disconnect AHS CM harness connector and "ACTIVE HOOD LIFT ACTUATOR RH" harness connector.

Measure the resistance between ground terminal of "ACTIVE HOOD LIFT ACTUATOR RH" harness connector and chassis ground.

Is the measured resistance within the specification?

	▶ Go to "Check short to battery in ground circuit" as below.
	▶ Repair open in "ACTIVE HOOD LIFT ACTUATOR RH" ground circuit and go to "Verification of Vehicle Repair".

IG key "OFF" and engine "OFF".

Disconnect AHS CM harness connector and "ACTIVE HOOD LIFT ACTUATOR RH" harness connector.

IG key "ON" and engine "OFF".

Measure the voltage between ground terminal of "ACTIVE HOOD LIFT ACTUATOR RH" harness connector and chassis ground.

Is the measured voltage within the specification?

	▶ Go to "Verification of Vehicle Repair" procedure.
	▶ Repair short to battery in "ACTIVE HOOD LIFT ACTUATOR RH" ground circuit and go to "Verification of Vehicle Repair".
