DTC Descriptors
DTC B3604 02
- Adjustable Pedal Forward Switch Circuit Short to Ground
DTC B3605 02
- Adjustable Pedal Rearward Switch Circuit Short to Ground
Diagnostic Fault Information
Circuit/System Description
Ground is supplied at all times to the adjustable pedal switch. When the pedals switch is pressed, a 5 V reference voltage is applied through the
switch contacts and the switch signal circuit to the memory seat control module. The memory seat control module then commands the adjustable
pedals motor to move in response to the switch signal.
Conditions for Running the DTC
The memory seat control module must be powered.
Conditions for Setting the DTC
The forward and rearward switch signal circuits are active at the same time.
