992G Wheel Loader and 854G Wheel Dozer Steering System Monitoring System (Steering Functions)

There are two types of monitoring systems that may be used on these machines. The standard system is the Vital Information Display System (VIDS). This system indicates the status of basic machine functions. This includes the steering system.

The second type of monitoring system is the optional Vital Information Management System (VIMS). This system also indicates the status of basic machine functions. This includes the steering system. VIMS is standard on the AZX and A4W models.

Vital Information Display System (VIDS)

(1) Action lamp. (2) Message center module. (3) Alert indicator. (4) Universal gauge. (5) Dash data link connector. (6) Message area.

On machines that use the VIDS, data link connector (5) is available. On machines that use the VIMS, two data link connectors are available.

Dash data link connector (5) is located under the dashboard, but near the center of the dashboard. Dash data link connector (5) allows information from the VIDS or the VIMS to be downloaded to a separate service tool.

Machines that use the VIMS also have additional switches and sensors on the machine. These additional components are connected to the monitoring system.

Either monitoring system alerts the operator if a loss of steering oil pressure occurs. A loss of steering oil pressure causes a Warning Category 3 to occur.

A Warning Category 3 alerts the operator that engine shutdown should occur as soon as possible. This helps prevent injury to the operator or potential damage to the machine.

A Warning Category 3 causes both action lamp (1) and alert indicator (3) to flash. A Warning Category 3 also causes the action alarm to sound. A message also appears in message area (6). In some cases, universal gauge (4) may show a relative value.

Note: Do NOT operate the machine until the cause of the warning has been corrected.

For the steering system, several problems that can appear in message center module (2) follow. Problems that appear below in bold text indicate a possible Warning Category 3.

  • STRNG OIL PRES LO

  • STRNG OIL TEMP HI
