Diagnostic Trouble Code (DTC) Information HLDF-B118002

Condition

The High Level Display Front (HLDF) operates the display up/down by means of electric motors. The control module checks the information from the limit position switches during raising and lowering.

If the signal from the limit switches is lost the control module makes four attempts to raise display up/down. At each attempt the control module waits for 10 seconds for signal from the limit switches.

The diagnostic trouble code (DTC) is stored if the control module detects that:

Information from upper limit switch lost.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:

Ignition switch position II.

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.
