, and is categorized as a "General Failure Information" code due to a missing message

The Pivi Pro and InControl Touch Pro systems run on complex Linux/Android-based operating systems. Sometimes, an over-the-air (OTA) update fails to write properly to the internal NAND flash memory. Alternatively, a corrupted system file causes the processor to fail its internal checksum verification. Verdict: Requires a manual flash of the TSM firmware. land rover jaguar b13c2-49

A software update will NOT make a seized fan work. It only helps marginal cases. , and is categorized as a "General Failure

| Fix | Procedure | Success Rate | |-----|-----------|---------------| | | Replace the complete air suspension valve manifold (Land Rover part numbers: LR134160, LR110837, LR156389 depending on model). Perform calibration/height reset. | 80% | | 2. Module firmware update | Reprogram Ride Level Control Module using JLR-approved software (if TSB JTB00518 or similar applies). | 10% | | 3. Repair corroded connector | Clean terminals, apply dielectric grease, replace damaged pins in harness side. | 5% | | 4. Replace suspension control module (if integrated separately from valve block – earlier models). | Module replacement + parameter restoration via SDD. | 5% | Verdict: Requires a manual flash of the TSM firmware

Before replacing hardware, check the module’s software version. Using JLR SDD or a dealer-level tool, update the ACM/TSDM to the latest calibration. The update modifies the self-test tolerance, allowing for slightly higher internal temperature thresholds and fan speed tolerances. This resolves false positives.
