When the electronic control is in the normal mode , the alert indicators are turned ON when a fault is detected. The Real Time Error Code is a function that is a part of the Data Mode. The function is used in order to display the faults that are detected. Refer to System Operation, "Normal Operation" for detailed information about the Data Mode.
The Error Log is a function of the Calibration Mode. The function is used in order to display detected faults that existed at some time during machine operation. The faults do not exist presently.
When a sensor fault is present, the corresponding alert indicator on the monitor panel is activated. Example: The following conditions can occur if the coolant temperature sensor is shorted to the +battery:
The corresponding error code is stored in memory. The engine coolant temperature gauge displays a temperature that is not
within specifications. The action lamp is FLASHING.
If the engine overheats, the second two indications also occur.

(6) Solution
Preparations (1) - The block provides information for the preliminary arrangements that must be made before you can troubleshoot.
Problem Description (2) - The block indicates problems that are shown by the character display.
Diagnostic Code (3) - The block indicates the specific codes.
Troubleshooting Step (4) - The block shows items that must be checked with a multimeter.
Probable Cause (5) - The block shows the probable cause(s) of a problem.
Solution (6) - The block shows the corrective action that should be completed in order to solve a particular problem. The statement "Replace" includes "Repair if possible".
Check the connectors before troubleshooting. Check the specified connectors for improper connections. A loose contact between two connectors can be caused by water in the connectors. An inspection of the connector discovers problems that must be corrected prior to troubleshooting.
When you perform a continuity check, first turn the starter switch to the OFF position in order to secure the power supply. This prevents damage to the tester and/or a short circuit of the power supply.
When you perform a voltage check, first turn the starter switch to the ON position in order to energize the power supply. Run the engine during voltage checks. When the engine is not running, stable signals cannot be received from the controller.
Explanation of the Terms
The following section is an explanation of the terms that are used in the troubleshooting procedure.
"CONN8F (6) - (8) : 0 Ohms" -
"(6)" - The pin number
"(8)" - The indication of a short circuit
"CONN8" - The number of the connector
"F" - The female "F" or male "M" half of the connector
0 Ohms - Continuity exists or no resistance. "infinite" indicates that no continuity exists or infinite resistance
"(Other than [/em/])" - The term indicates that all of the components of the connector require action except for the item that is specified in the brackets. "[/em/]"
