TRACTION CONTROL SYSTEM (TCS)

151

Circuit Description

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 21. If the
TCS input circuit is open or short, this failure code will be set.

RESONANCE FLAP

199

Circuit Description

A pneumatically actuated resonance flap is located on the intake manifold, and will be opened 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 valve will be adjusted by ECM and
resonance flap will 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 valve will not be adjusted by ECM and resonance
flap will be open. The collected air in the air collection housing will not be divided and intake air passage will be
shorten.

STOP LAMP SWITCH

Circuit Description

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 released.
