C0238

CIRCUIT DESCRIPTION
The throttle position signal is used by the Accelerator and Servo Control Module (ASM) to control the actual throttle position that is requested by the Electronic Brake Traction Control Module (EBTCM). The EBTCM compares the Delivered throttle position sensor value that is sent from the ASM to the throttle position sensor value sent from the Powertrain Control Module (PCM) over the Class 2 serial data line.

CONDITIONS FOR SETTING THE DTC
Diagnostic Trouble Code (DTC) C0238 will set if the Electronic Brake Traction Control Module (EBTCM) detects a difference between the Powertrain Control Module (PCM) throttle position and the throttle position sent from the Accelerator and Servo Control Module (ASM).

ACTION TAKEN WHEN THE DTC SETS
^ A malfunction Diagnostic Trouble Code (DTC) is stored.
^ The Traction Control System (TCS) is disabled.

CONDITIONS FOR CLEARING THE DTC
^ Condition for Diagnostic Trouble Code (DTC) is no longer present and Scan tool clear DTC function is used.
^ 100 ignition cycles have passed with no DTCs detected.

DIAGNOSTIC AIDS
^ It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
^ If an intermittent malfunction exists refer to General Electrical Diagnosis in Diagnostic Aids.

TEST DESCRIPTION
The number(s) below refer to the step number(s) on the diagnostic table.
2. This step checks if the Powertrain Control Module (PCM) detected a fault.
