V50 L5-2.4L VIN 39 B5244S7 (2005)
With breakout box connected to central electronic module (CEM): Measure the voltage on the pins that correspond to the different voltage supplies from
the Start control module (SCU) for all key positions, and check that it corresponds with the table that describes in which key position each voltage supply
Check, using Volvo's diagnostic tool, that the key has been approved by the immobilizer.
With loose Start control module (SCU): Measure the resistance between the control module pins in the different key positions. Compare the result with
the table that describes in which position each voltage supply is active. Open switches have a resistance of at least 100 m ohms. Closed switches have a
resistance of a maximum of 100 m ohms.
