Operation

OPERATION

The adjustable pedal system indicator gives an indication to the vehicle operator when the adjustable pedals have been automatically disabled. This indicator is controlled by the instrument cluster logic circuit based upon cluster programming and electronic messages received over the Controller Area Network (CAN) data bus from the Memory Seat Module (MSM).

The adjustable pedal system indicator function of the reconfigurable dot matrix Organic Light Emitting Diode (OLED) display unit is completely controlled by the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the instrument cluster receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the OLED adjustable pedal system indications will always be OFF when the ignition switch is in any position except ON or START. The instrument cluster will turn ON the adjustable pedal system indicator for the following reasons:

- Cruise Control Engaged Message - Each time the cluster receives an electronic cruise control engaged adjustable pedal system lockout message from the MSM, the ADJ. PEDALS DISABLED and CRUISE CONTROL SET textual warnings are cycled. The two parts of the message are cycled about every three seconds until the MSM sends an electronic message to cancel the adjustable pedal lockout event, until the cluster arbitrator logic determines that another display request has priority, or until the ignition switch is turned to the OFF position, whichever occurs first.
- Transmission In Reverse Message - Each time the cluster receives an electronic cruise control engaged adjustable pedal system lockout message from the MSM, the ADJ. PEDALS DISABLED and SHIFTER IN REVERSE textual warnings are cycled. The two parts of the message are cycled about every three seconds until the MSM sends an electronic message to cancel the adjustable pedal lockout event, until the cluster arbitrator logic determines that another display request has priority, or until the ignition switch is turned to the OFF position, whichever occurs first.

The MSM continually monitors inputs from the memory switch through the Driver Door Module (DDM), the Wireless Ignition Node (WIN) (also known as the Sentry Key Immobilizer Module/SKIM, the Sentry Key REmote Entry Module/SKREEM or the Wireless Control Module/WCM), the Powertrain Control Module (PCM) and, if equipped, the Transmission Control Module (TCM) to determine the proper outputs to the adjustable pedal system components. The MSM then sends the proper lamp-ON or lamp-OFF message to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN).

For proper diagnosis of the memory system, the MSM, the EMIC, the CAN data bus or the electronic communication related to adjustable pedal system indicator operation a diagnostic scan tool is required. Refer to the appropriate diagnostic information.
