Memory system disabled jeep
The Electronic Vehicle Information Center (EVIC) uses both non-switched and ignition switched sources of battery current so that some of its features remain operational at any time, while others may only operate with the ignition switch in the On position. When the ignition switch is turned to the On position, the EVIC display will return to the last function being displayed before the ignition was turned to the Off position.
The EVIC system is comprised of several different components that communicate over the Controller Area Network (CAN) Data Bus. If the system is inoperative a scan tool and the appropriate diagnostic information must be used to diagnose the system.
The EVIC control switches are used to operate the different functions of the EVIC system. Pressing and releasing the MENU button (4) will change the mode displayed to one of the Personal Settings. The STEP button (3) is used to make a selection from the Personal Setting displayed at that time. Pressing and releasing the C/T (compass/thermometer) button (1) will cause the EVIC to return to the compass/thermometer/trip computer display mode from any other mode. From the compass/thermometer/trip computer display mode the STEP button (3) is used to scroll through and make selections in the Trip Functions. Pressing and releasing the RESET button (2) resets the trip computer screen displayed at that time.
EVIC DISPLAY MODES
SYSTEM STATUS MODE

Compass/Temperature/Trip Computer Mode
This display provides the outside temperature, one of the eight compass headings to indicate the direction the vehicle is facing, and vehicle trip information. The compass and temperature display is the normal display. When the C/T button is pressed the compass/temperature display returns.
The trip computer function will be displayed if the STEP button is pressed from the Compass/Temperature display mode. The trip computer displays the following information:
- Average fuel economy
- Distance to empty
- Trip A
- Trip B
- Elapsed time
- Miles to service
- Tire pressure display (if equipped)
- Oil Pressure (SRT-8 only)
- Oil Temperature (SRT-8 only)
Universal Garage Door Transceiver
The Electronic Vehicle Information Center (EVIC) features a driver-interactive display which includes HomeLink system messages. For additional information on the universal transceiver (Refer to 8 — ELECTRICAL/OVERHEAD CONSOLE/UNIVERSAL TRANSMITTER — DESCRIPTION).

operation a diagnostic scan tool is required. Refer to the appropriate diagnostic information.
Memory System Indicator — Description
A memory system indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with the optional memory system this
indicator is electronically disabled. The memory system indications appear within the reconfigurable dot matrix Organic Light Emitting Diode (OLED)
display unit. The memory system indicator consists of a single textual message or a cycling textual two message set which appears in place of the
compass/trip computer information in the dot matrix display. The single messages are MEMORY #1 POSITIONS SET, MEMORY #2 POSITIONS
SET, DRIVER 1 MEMORY or DRIVER 2 MEMORY. The two message sets are MEMORY SYSTEM DISABLED followed by either
SEATBELT BUCKLED along with the International Control and Display Symbol icon for Seat Belt or MEMORY SYSTEM DISABLED followed
by VEHICLE NOT IN PARK.
The dot matrix OLED is soldered onto the cluster electronic circuit board, and is visible through a window with a smoked clear lens located on the lower
edge of the tachometer gauge dial face of the cluster overlay. The dark lens over the OLED prevents it from being clearly visible when it is not
illuminated. The textual messages appear in the same white color and at the same lighting level as the compass/trip computer information when they are
illuminated by the instrument cluster electronic circuit board.
The memory system indicator is serviced as a unit with the OLED in the instrument cluster.
Memory System Indicator — Operation
The memory system indicator gives an indication to the vehicle operator of the system status or when the system has 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 memory 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 memory 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 memory system indicator for the following reasons:
Memory Set Message — Each time the cluster receives an electronic memory set message from the MSM, the appropriate MEMORY #1
POSITIONS SET or MEMORY #2 POSITIONS SET textual message is displayed. The message is displayed 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.
Memory Recall Message— Each time the cluster receives an electronic memory recall message from the MSM, the appropriate DRIVER 1
MEMORY or DRIVER 2 MEMORY textual message is displayed. The message is displayed 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.
Seatbelt Buckled Message — Each time the cluster receives an electronic seatbelt buckled memory system lockout message from the MSM, the
MEMORY SYSTEM DISABLED and SEATBELT BUCKLED textual messages and icon are cycled. The two parts of the message are cycled
about every three seconds until the MSM sends an electronic message to cancel the memory system 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.
Vehicle Not In Park Message — Each time the cluster receives an electronic vehicle not in Park memory system lockout message from the MSM,
the MEMORY SYSTEM DISABLED and VEHICLE NOT IN PARK textual messages are cycled. The two parts of the message are cycled
about every three seconds until the MSM sends an electronic message to cancel the memory system lockout event, until the cluster programming
or another request requires a different OLED display, or until the ignition switch is turned to the OFF position, whichever occurs first.
The MSM continually monitors inputs from the seatbelt switch through the instrument cluster, also known as the Cab Compartment Node (CCN), the
Driver Door Module (DDM), the Wireless Ignition Node (WIN), the Powertrain Control Module (PCM) and, if equipped, the Transmission Control
Module (TCM) to determine the proper outputs to the memory system components. The MSM then sends the proper lamp-ON or lamp-OFF message to
the CCN.
For proper diagnosis of the memory system, the MSM, the CCN, the CAN data bus or the electronic communication related to memory system indicator
operation a diagnostic scan tool is required. Refer to the appropriate diagnostic information.
No Bus Indicator — Description
A no-bus indicator is standard equipment on all instrument clusters. The no-bus indication appears within the fixed segment odometer Vacuum
