DTC P0771 Lincoln

Description

The multimedia module (MMM) checks DC voltage on the signal cable from the antenna amplifier. The traffic message channel (TMC) is transmitted via the antenna amplifier to the TMC receiver in the Multimedia module (MMM). The diagnostic trouble code (DTC) is stored if the control module detects that: Direct current (DC) is too high or there is no direct current (DC). The control modules test for the diagnostic trouble code (DTC) starts in the event of: Ignition switch position II. Request for self-test. Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
