1. Adjustable Pedals Malfunction |
Battery voltage is supplied at all times to the adjustable pedal switch from the memory seat module (MSM). When the pedals switch is pressed, battery voltage is applied through the switch contacts and the switch signal circuit to the MSM. The MSM then commands the adjustable pedals motor to move in response to the switch signal.
The MSM must be powered.
• | If the adjustable pedals switch circuit is active in one direction and the switch for the opposite direction is pressed, this DTC will set. |
• | A short to voltage on a switch signal circuit. |
Adjustable pedals operation will be disabled.
• | The current DTC will clear and set the code to history, 3 seconds after the fault is no longer present and the power mode changes to OFF then back to ACC or RUN. |
• | The history DTC will clear after 50 consecutive fault-free ignition cycles have occurred. |
The MSM may be referenced as the driver position module.
Adjustable Pedals Description and Operation
Control Module References for scan tool information
Ignition ON, observe the scan tool Pedal Forward Switch and Aft Switch parameters while pressing the adjustable pedal switch in both directions. The readings should change between Inactive and Active for both directions.
⇒ | If not the specified value, test the appropriate switch signal circuit for a short to voltage. If the circuit tests normal, replace the MSM. |
⇒ | If not the specified value, replace the adjustable pedal switch. |
⇒ | If greater than the specified range, replace the adjustable pedal switch. |
⇒ | If not the specified value, replace the adjustable pedal switch. |
⇒ | If greater than the specified range, replace the adjustable pedal switch. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
