Circuit Description

Electronic Brake and Traction Control Module (EBTCM) controls Pulse Width Modulation (PWM) signal on desired torque circuit while monitoring wheel speed sensors to detect slippage.

Output Driver Modules (ODM) are used by PCM to turn on current-driven devices needed to control various engine and transaxle functions. Each ODM can control up to 7 outputs, including traction control delivered circuit, by supplying ground to device PCM is commanding on. ODMs can diagnose each circuit individually. If ODM "B" output 3 (traction control delivered torque circuit) detects an improper voltage level, P1653 is set.

Conditions required to set DTC are:

• Ignition is on.
• An improper voltage level has been detected on traction control delivered driver circuit.
• Listed conditions present for greater than 30 seconds.
