Entering Display DTC Mode - MTC System
WARNING: This page is about a different car, the 2008 Dodge Magnum, 2008 Dodge Charger, and 2008 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
To enter the MTC system's Display DTC Mode, perform the following:
NOTE:
An active DTC 33 will prevent the control from entering diagnostic mode and performing certain diagnostic functions. It will also prevent proper A/C mode switch and status indicatorfunction. If this occurs, refer to *A/C HEATER CONTROL WILL NOT ENTER DIAGNOSTIC MODE (MTC) in HEATING & AIR CONDITIONING - ELECTRICAL DIAGNOSTICS
article for the diagnostic test procedure.
- Turn the ignition to the On position.
- Turn the blower motor control (1) to the On position.
- Press the A/C mode switch (2) down, turn the blower motor control to the Off position, wait until both LEDs illuminate (approximately 5 seconds) and then release the A/C switch. If there are active or stored DTCs to display, the A/C status indicator (3) will begin to flash. If there are no active or stored DTCs to display, the LEDs on the A/C-heater control (4) will turn off and the system will automatically exit the mode of operation.
- To manually exit Display DTC Mode, either turn the ignition off or disconnect the negative battery cable from the battery.
