Circuit Description
Ignition voltage is supplied directly to the cooling fan relay coil. The ECM controls the relay by grounding the control
circuit. When the ECM is commanding a command ON, the voltage of the control circuit should be low (near 0 volt).
When the ECM is commanding the control circuit should be high (near battery voltage). If the fault detection circuit
senses a voltage other than what is expected, the fault line status will change causing the fault code to set.

Circuit Description
Cruise control is an automatic speed control system that maintain a desired driving speed without using the accelerator
pedal. The vehicle speed must be greater than 40 km/h to engage cruise control.

Battery voltage is supplied to the TCS warning lamp with the ignition in ON and START. The warning lamp can be
activated only by the Electrical Brake Control Module (EBCM) internally supplying ground to terminal 32. If the TCS
input circuit is open or short, this failure codewill be set.

Circuit Description
A pneumatically actuated resonance flap is located on the intake manifold, andwill beopened and closed by load,
which operates resonance flap according to engine and controlled by ECM and rpm.
Resonance flap is closed at idle/partial load (less than 3,800/rpm). The switch valvewill be adjusted by ECM and reso-
nance flapwill be closed. By increasing air flow passage through dividing intake air flow toward both air collection
housing. This leads to a significant increase in the torque in the lower speed range.
Resonance flap is open at full load (over 3,800/rpm). The switch valvewill not be adjusted by ECM and resonance flap
will beopen. The collected air in the air collection housingwill not be divided and intake air passage will be shorten.

The stop lamp switch is normally opened. When the ignition switch ON and brake ON, the battery voltage is supplied to
the ECM. A scan tool should display ON when brake pedal is depressed and should read OFF with brake pedal rele-
ased.
