NOTE
When the ignition is turned to ON, the M32QR
ABS Pressure Modulator Valve solenoids are
briefly energized. This can be audibly detected
by a rapid cycling of the PMVs. If the air system
is fully charged and the service brake pedal is
depressed when ignition is turned to ON, the
modulator valves create a sharp audible "chuff"
of air pressure.
CAUTION
Do not press the accelerator pedal before
starting. This could result in an electronic
control unit fault and degrade the fuel system
control.
