Tuesday Tech Tip #3 - Red LED on Module

Summary

In this week’s episode of Tuesday Tech Tips presented by Reimer Tuning, host Mackenzie tackles common questions regarding an additional module included in certain kits, specifically addressing applications for machines such as Kubota, Takeuchi, and Caterpillar skid steers. The focus of the episode is on a red LED light found on the module, which signals a CAN bus communication issue. Mackenzie explains that the problem may arise either from the engine control module’s connector or, as highlighted in this episode, the diagnostic port. Proper troubleshooting involves checking the CAN high and CAN low readings, which should show around 2.6 volts and 2.4 volts, respectively. If these readings fall outside the expected range, wiring issues may be the cause of the red LED indicator. Once the wiring is addressed, the LED should change to a solid green, signaling that the machine is ready for operation. Mackenzie wraps up the episode with encouragement for viewers to engage with more content by liking and subscribing for future tips.
