Land Rover Jaguar B13c2-49 [PREMIUM 2026]

Log in to Topix (JLR’s service portal) and check your VIN. One TSB (LTB01796v3) specifically addresses B13C2-49 and recommends a fan replacement for versions before module hardware level “H”.

Unfortunately, JLR does not sell the sensor mat separately. You have two options:

Check these common locations:

| Location | Likely meaning | |----------|----------------| | Sticker on a module (ECU, ABS pump) | Internal manufacturer code | | Engraved on a metal bracket | Supplier part ID | | On a wiring harness tag | Assembly line routing code | | Diagnostic scanner fault code | Possibly misread DTC (none matches this exactly) | | Battery label | Date/batch code (B13 = 2013 or 2023, C2 = plant code, 49 = week?) |

The radio, Bluetooth streaming, navigation voice prompts, and parking sensor beeps may stop working. Sometimes the audio works but cannot be changed because the screen is dead. land rover jaguar b13c2-49

The dealer solution. JLR will require you to purchase a new TSM. It must be programmed to your VIN using online servers. If you buy a used TSM from eBay, it will almost certainly trigger Component Protection (CP), and the dealer will not be able to code it to your car without original proof of purchase.

A failed OTA (over-the-air) update or incomplete flash of the infotainment system can cause erroneous internal self-test failures. In these rare cases, the hardware is fine, but the software logic falsely triggers the -49 code. Log in to Topix (JLR’s service portal) and check your VIN

If you have a code reader capable of reading JLR-specific codes (such as the iCarsoft CR Max, Autel Ultra, or JLR SDD), follow this professional workflow.
