DIAGNOSTIC INFORMATION AND PROCEDURES DIAGNOSTIC CODE INDEX DIAGNOSTIC CODE INDEX DIAGNOSTIC STARTING POINT - ADJUSTABLE PEDALS Begin adjustable pedal system diagnosis with the Diagnostic System Check - Vehicle . The Diagnostic System Check will provide the following information:  The identification of the control modules which command the system.  The ability of the control modules to communicate through the serial data circuit.  The identification of any stored DTCs and their status. The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

SCAN TOOL DATA DEFINITIONS 8 Digit GM Part Number The scan tool displays the part number of the module. Battery Voltage The scan tool displays 0-16 volts. The level of battery voltage at the module. Calibration ID The scan tool displays a 4 digit number. This number designates the calibration or program level used in the PROM. Current The scan tool displays 0-127.5 amps. The current measured during adjustable pedals or seat operation. Hardware Level The scan tool displays a 4 digit number representing the level of hardware incorporated into the module. Julian Date of Build The scan tool displays a 3 digit number. This number is the day of the year that the module was built. PROM ID The scan tool displays a 4 digit number. This is the identification number of the PROM that is incorporated into the module. Pedals Position Sensor The scan tool displays 0-5.0 volts or 0-255 A/D. The sensor potentiometer provides an analog voltage which varies directly with the adjustable pedals position. High scan tool values (volts or A/D) indicate that the pedals are in the froward position and low values indicate that the pedals are in the rearward position.

The scan tool displays Inactive/Active. When the adjustable pedals forward switch is activated, the scan tool will momentarily display switch input to the driver position module as Active. Pedals Forward - Output The scan tool displays Inactive/Active. When the adjustable pedals forward switch is activated or when a memory recall occurs, the scan tool will momentarily display Active while the output from the driver position module is commanding the adjustable pedals motor in the forward direction. Pedals Rearward - Input The scan tool displays Inactive/Active. When the adjustable pedals rearward switch is activated, the scan tool will momentarily display the switch input to the driver position module as Active. Pedals Rearward - Output The scan tool displays Inactive/Active. When the adjustable pedals rearward switch is activated or when a memory recall occurs, the scan tool will momentarily display Active while the output from the driver position module is commanding the adjustable pedals motor in the rearward direction. Software Level The scan tool displays the 4 digit number of the software incorporated into the module. Year Module Built The scan tool displays a 4 digit number. This number represents the year the module was built.

Circuit/System Description The adjustable pedals forward and rearward switches are inputs to the memory seat module. The memory seat module supplies the switch assembly with a battery positive reference voltage. When the switch is operated to the forward or rearward direction, battery positive voltage is applied to the forward or rearward switch signal inputs. Conditions for Running the DTC System voltage to the memory seat module must be 9-16 volts. Conditions for Setting the DTC The forward and rearward switch signal circuits are active at the same time. Action Taken When the DTC Sets The adjustable pedals will be disabled. Conditions for Clearing the DTC The fault is no longer present.

Scan Tool Reference Scan Tool Data List Circuit/System Testing 1. Disconnect the adjustable pedal switch connector. 2. Ignition ON, verify that both adjustable pedal switch parameters to the memory seat module are Inactive.  If 1 of the switch parameters is always Active test the affected switch signal circuit for a short to voltage. If the signal circuit tests normal replace the memory seat module. 3. If the circuit tests normal replace the adjustable pedal switch. Repair Procedures Perform the Diagnostic Repair Verification Diagnostic Repair Verification after completing the diagnostic procedure.

Circuit/System Description The memory seat module monitors the location of the adjustable pedals using the adjustable pedals position sensor. The adjustable pedals position sensor is supplied with 5-volt reference and ground circuits from the memory seat module. The position sensor signal circuit is referenced from ground within the memory seat module. The signal voltage monitored by the memory seat module ranges from 0.45-4.55 volts and is determined by the wiper location on the resistor within the position sensor. Conditions for Running the DTC System voltage to the memory seat module must be 9-16 volts. 2007 Cadillac Escalade 2007 ACCESSORIES & EQUIPMENT Adjustable Pedals - Avalanche, Escalade, Suburban, Tahoe & Yukon
