14857A11 Mariner OIL WARNING MODULE

Active Diagnostic Codes
An active diagnostic code represents a problem with the electronic control system. Correct the condition as soon as possible. If the condition that generates the diagnostic code occurs only for a brief moment, the message will disappear and the diagnostic code will be logged in the memory of the Electronic Control Module (ECM).Logged Diagnostic Codes
When the ECM generates a diagnostic code, the ECM will log the code in the permanent memory of the ECM. The ECM has a diagnostic clock that is internal. This clock records the hour of the first occurrence, the hour of the last occurrence, and the number of occurrences of the code. Knowing the timing of the code and knowing the frequency of the code can be a valuable indicator. These indicators are helpful when problems that are intermittent are being investigated.Note: Cat ET can be used to retrieve logged codes and Cat ET can be used to erase logged codes. Logged diagnostic codes will automatically be deleted if no additional occurrences are recorded in 100 hours. Be aware of the following information when logged diagnostic codes are investigated.
Some diagnostic codes may log occurrences that did not result in operator complaints. A diagnostic code is logged at a specific time. This time should correlate to a complaint. A repair may not be necessary if there is no correlation.
The most likely cause of an intermittent problem is a faulty connection or damaged wiring. The next most likely cause of an intermittent failure is a component failure such as a sensor or a switch. The least likely cause of an intermittent problem is a failure of the ECM.
Diagnostic codes that are logged repeatedly may indicate a problem that needs special investigation.
The code number will direct you to a procedure in troubleshooting guide. If the symptoms continue, use the proper procedure for troubleshooting the symptoms that have been experienced by the operator. Refer to Troubleshooting Without A Diagnostic Code.Note: Always clear logged diagnostic codes after investigating and correcting the problem which generated the code.

Output voltage from a typical analog temperature sensor
Illustration 1 indicates the signal range for a typical analog sensor. Diagnostic codes will be generated if the output signal for the sensor is below 0.2 VDC or above 4.8 VDC.Cross-Reference for SPN-FMI Code to CID-FMI (Diagnostics)
