Here, we will check and fix the causes one by one. <\/p>\n In this troubleshooting guide, first, we will introduce you to the causes, how they can impact the code to occur, and ways to get rid of them. . <\/p>\n As the code means ‘Battery Disconnected’ along with ‘TCM Internal,’ this indicates there might be something not good with the battery. <\/p>\n And chances are the battery connection becomes loose or the wiring harness becomes damaged. If this happens, the battery can’t charge properly. <\/p>\n And due to a lack of battery charge, the transmission control module of your Jeep SUV might start to malfunction. <\/p>\n The transmission control system needs power from the battery in order to control the transmission. Moreover, it needs constant power for minimal operation from the battery. <\/p>\n The transmission control module can’t calculate the checksum data properly if it can’t get power. <\/p>\n As the day advances, the wiring harness of the battery in your Jeep might wear out or be damaged. <\/p>\n So, you need to check the wiring harness visually to see any further damage. If you find any damage or the wiring harness is worn out, you should replace it.<\/p>\n If you find no major issues with the wiring harness, then it makes all sense to check if the battery is dead. The transmission control module cannot function when the battery on your Jeep malfunctions.<\/p>\n And suppose the transmission control module of your Jeep Patriot is not functioning properly due to power interruption. <\/p>\n In that case, there is a mismatch between the calculated stored checksum value and the checksum value acquired by the transmission control module. For this, the Patriot code p161B can take place. <\/p>\n What you need to do here is to check if the battery is dead using a multimeter. Now, this can be tricky if you don’t have a decent idea about checking the battery or don’t have the multimeter. <\/p>\n Therefore, it will be better if you go with the mechanic. And if the battery turns out dead or the lasting period is finished, you should replace it, which might cost you $340-$400.<\/p>\n\n
