Pinpoint Test B: The Adjustable Pedals Are Inoperative/Does Not Operate Correctly - Using the Memory SET Switch or the Remote Keyless Entry (RKE) Transmitter


Normal Operation

When the desired memory position is selected using the memory SET switch or the Remote Keyless Entry (RKE) transmitter, the Driver Seat Module (DSM) communicates the desired pedals position in a message on the Medium Speed Controller Area Network (MS-CAN) bus to the Body Control Module (BCM). The BCM (Body Control Module) acts as a gateway module, relaying the message to the Steering Column Control Module (SCCM) over the High Speed Controller Area Network (HS-CAN) bus. The SCCM (Steering Column Control Module) then sends current in one direction to the adjustable pedals motor to move the pedals forward and in another direction (reversed polarity) to move the pedals rearward.

The SCCM (Steering Column Control Module) uses a Hall-effect sensor that is integral to the pedals motor to identify the current pedal position. The SCCM (Steering Column Control Module) sends a reference voltage along one circuit, through the sensor and back to the SCCM (Steering Column Control Module) along the signal return circuit.

If the vehicle is equipped with the memory feature but the SCCM (Steering Column Control Module) is incorrectly configured, memory recall may not function correctly when the memory SET switch or the RKE (Remote Keyless Entry) transmitter is used to adjust the pedal position.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Foreign objects or material

- Adjustable accelerator pedal and motor with attached cable

- Adjustable brake pedal and bracket

- RKE (Remote Keyless Entry) transmitter

- DSM (Driver Seat Module)

- SCCM (Steering Column Control Module)

- Incorrect SCCM (Steering Column Control Module) configuration

- BCM (Body Control Module)

PINPOINT TEST B : THE ADJUSTABLE PEDALS ARE INOPERATIVE/DOES NOT OPERATE CORRECTLY - USING THE MEMORY SET SWITCH BUTTONS OR THE RKE (Remote Keyless Entry) TRANSMITTER

NOTICE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.

Yes
GO to B5.
No
CORRECT the adjustable pedals motor installation. REFER to Fuel Delivery and Air Induction. TEST the system for normal operation.

B5 INSPECT FOR FOREIGN OBJECTS OR MATERIAL

- Inspect the adjustable brake pedal and accelerator assemblies for foreign material causing a binding condition.

Are the pedal assemblies free from foreign material?

Yes
GO to B6.
No
REMOVE the foreign material. TEST the system for normal operation.

B6 CHECK FOR DSM (Driver Seat Module) OR BCM (Body Control Module) DTCs

- Ignition ON.

- Connect the scan tool.

- Enter the following diagnostic mode on the scan tool: Self-Test- DSM (Driver Seat Module).

- Enter the following diagnostic mode on the scan tool: Self-Test- BCM (Body Control Module).

- Record any DTCs retrieved from the DSM (Driver Seat Module) or the BCM (Body Control Module).

Was DTC U0140 retrieved from the DSM (Driver Seat Module) or was DTC U0212:87 retrieved from the BCM (Body Control Module) ?

Yes
If DTC U0140 is retrieved from the DSM (Driver Seat Module), REFER to Seats to diagnose the lost communication concern.

If DTC U0212:87 is retrieved from the BCM (Body Control Module), REFER to Body Control Systems to diagnose the lost communication concern.
