End of test

2. Check component M16/6 (Throttle valve actuator).

Test 2.1: Check component M16/6 (Throttle valve actuator) using actual value.

Test 2.2: Check component M16/6m1 (Actuator motor) by means of actuation.

Test 2.3: Check internal resistance of component M16/6m1 (Actuator motor).

Test 2.4: Check internal resistance of component M16/6 (Throttle valve actuator).

Test 2.5: Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).

2.1. Check component M16/6 (Throttle valve actuator) using actual value.

Warning!Communication with ECU required.
