Circuit/System Verification

Observe the function of the right and left turn signal lamps while turning the hazard lamp switch ON and OFF. The right and left turn signal lamps

should cycle ON and OFF while the hazard lamp switch is ON and remain OFF when the hazard lamp switch is OFF.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the P17 info display module.

2. Ignition ON, test for greater than 10V between the signal circuit terminal 16 and ground.

瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the K9 BCM.

3. If all circuits test normal, replace the P17 info display module.

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.
