The function of the solenoid is to control (trigger) oil pressure to the hydraulic valve depressors.
The solenoid is supplied with voltage from the system relay via fuse and ground (control) internally in the engine control module (ECM).
The system has two solenoids that each supplies a number of cylinders.
The solenoids are located on each side of the engine between the camshafts.
The solenoids can be diagnosed by the Engine control module (ECM).

Emissions warning lamp
The emissions warning lamp in the Driver Information Module (DIM) has a warning symbol. This warning symbol varies depending on the market. The
warning symbols are:
Engine symbol" (not USA)
CHECK ENGINE" (MIL - Malfunction Indicator Lamp, USA only).
The warning lamp lights when the start control module (SCU) is activated to position II. The warning lamp will go out after approximately 15 seconds or
if the engine is started when no fault is found in the engine management system.
If Readiness is not complete (certain diagnostic functions not completed), the warning lamp will flash instead of going out when the start control module
(SCU) is in position II.
The warning lamp will light if there is a fault in one of the parameters in the engine management system. The warning lamp will also light in response to
a request transmitted via the control area network (CAN) if there is a fault in the transmission control module (TCM) which affects emissions.
