Conditions:
- knock sensor - tightening torque = XX Nm
- observe the occupation safety rules when taking a test drive with connected diagnostics tester
Start the engine - engine speed = idling
connect with the control unit XX - engine
do a test drive
Conditions:
- engine temperature > XX °C
- idling -> partial load -> full load -> deceleration
- full load = engine speed > XXXX rpm
XX - Measured values group XXX
observe values
field X = X,XV - X,XV (knock sensor X - voltage - cylinder X)
field X = X,XV - X,XV (knock sensor X - voltage - cylinder X)
field X = X,XV - X,XV (knock sensor X - voltage - cylinder X)
field X = X,XV - X,XV (knock sensor X - voltage - cylinder X)
desired condition: (field X = field X = field X = field X) ± X,XXV
XX - end of communication
upon non--achievement of condition - check component:
- knock sensor
- knock sensor - line
- knock sensor - tightening torque
- knock sensor - tightening torque = XX Nm
