|---|---|---|---|
|
Detection condition
|
Determination conditions
|
• PCM receives abnormal signal from the engine oil level sensor.
• If the engine oil level signal from the engine oil level sensor does not change, an oil level change due to driving conditions can be considered.
|
|
|
Preconditions
|
• Battery voltage: 10—16 V *1
• The following DTC is not detected:
• Low-G (XY) sensor (built-into SAS control module) signal is normal
*1: Standard can be verified by displaying PIDs using M-MDS

Function Explanation (DTC Detection Outline)
• The PCM receives the signal from the engine oil level sensor and diagnoses the following malfunctions.
-
― The engine oil temperature is −35 °C {−31 °F} or more and an error signal on the engine oil temperature side from the engine oil level sensor is received continuously for 30 s or more.― A sensor malfunction signal from the engine oil level sensor is received continuously for 30 s or more.
• The PCM performs diagnosis when each of the preconditions is met during a drive cycle. If any of the above malfunctions is detected, a malfunction is determined, DTCs are stored and the engine oil level warning light is turned on.
• The PCM performs diagnosis when each of the preconditions is met during a drive cycle. If any of the above malfunctions is detected, a malfunction is determined, DTCs are stored and the master warning indication or engine oil level warning indication is displayed on the multi-information display.
Repeatability Verification Procedure
1. Start the engine and run it at idle.

|
Yes
|
Go to the next step.
|
|
No
|
Go to the troubleshooting procedure for DTC on freeze frame data.
|
||
|
4
|
PURPOSE: INSPECT FOR OTHER RELATED DTCs
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Are any other DTCs displayed?
|
Yes
|
Repair the malfunctioning location according to the applicable DTC troubleshooting.
|
|
No
|
Go to the next step.
|
||
|
5
|
PURPOSE: VERIFY IF THERE IS PID ITEM CAUSING DRASTIC CHANGES OF ACCELERATION FLUCTUATION BY INPUT SIGNAL TO PCM
• Access the following PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION.)
• Is the PID value within specification? (See ENGINE OIL LEVEL SENSOR INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See ENGINE OIL LEVEL SENSOR INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
|
Yes
|
Go to the next step.
|
|
No
|
Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
|
||
|
6
|
PURPOSE: VERIFY CONNECTOR CONNECTIONS
• Access the following PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION.)
• When the following parts are shaken, does the PID value include a PID item which has changed?
|
Yes
|
Repair or replace the applicable connector parts.
Go to Troubleshooting Diagnostic Procedure to perform the repair completion verification.
|
|
No
|
Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.

Repair completion verification 1
|
PURPOSE: VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
|
Yes
|
