The Engine Control Module (ECM) detects the following conditions:

• The signal voltage from the engine oil pressure sensor is greater than 4.95 VDC for more than eight seconds.
• The ECM has been powered for at least two seconds.

-The 168-01 Low ECM Battery Power is not active.

• The 232-03 5 Volt Supply voltage high is not active.

-The 232-04 5 Volt Supply voltage low is not active.

• The engine is not running or the engine coolant temperature is greater than 38 °C (100 *F).

 

The Engine Control Module(ECM)continuously creates a pull-up voltage on the signal wire for each sensor.The ECM uses this pull-up voltage in order to detect a problem in the signal circuit.When the ECM detects voltage that is above a threshold on the signal wire,the ECM activates a-3diagnostic code.When the ECM detects voltage that is below a threshold on the signal wire,the ECM activates a-4diagnostic code.

 

Note:There maybe a delay of 30 seconds in order for Caterpillar Electronic Technician(ET) to display an active diagnostic code.When you check for a diagnostic code,be sure to wait at least 30 seconds.

 

The most likely cause of a code is a problem with an electrical connector or wiring.The least likely cause of a code is the ECM.

 

Probable Causes:

1) ECM Connection

2) Sensor or harness failure

3) Failed ECM
