OEM Switch Circuit
The OEM switch is used by the electronic control module (ECM) to monitor an OEM-specific switch. The ECM monitors the signal on pin 12 for the engine/vehicle protection system.
The OEM switch is located in different locations, depending on the OEM and equipment model. Refer to the OEM service manual.
Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM. Refer to Procedure 019-032 (ECM Calibration Code) in Section 19 in the corresponding Troubleshooting and Repair Manual for the engine being serviced.
Verify with the driver the engine operating condition when the fault occurs. Depending on the engine speed and load, the OEM switch can detect a condition that falls below or exceeds the engine protection limit. Refer to the OEM service manual for more information.
