C2102 on Jeep
TPMS Receiver / Transmitter Reception Fault (Manufacturer-Specific)
C2102 on Jeep vehicles indicates tpms receiver / transmitter reception fault (manufacturer-specific). Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. C2102 is a manufacturer-specific chassis code within the Tire Pressure Monitoring System family (commonly Toyota/Lexus). It generally indicates the TPMS ECU failed to receive a valid signal from a wheel transmitter or detected a receiver-side reception problem for a specific sensor. The TPMS warning light usually illuminates and one or more tire pressures may not be reported. This is primarily an advisory/safety code; manually verify tire pressures while the fault is present.
Common Causes of C2102
- •Dead or weak TPMS sensor battery
- •Sensor ID not registered or mismatched
- •Faulty TPMS receiver, antenna, or wiring
- •RF interference near the vehicle
- •Failed or missing tire pressure sensor
- •TPMS control module fault
C2102 on Jeep by Model
Jeep Grand Wagoneer(1 issue)
- Electric Power Steering Rack Failure and Assist Loss2022-2024
The Grand Wagoneer's electric power steering (EPS) rack-and-pinion assembly experiences premature failure, manifesting as sudden loss of power steering assist, wandering on the highway, or excessive steering effort. The EPS motor or internal torque sensor fails, triggering a steering warning light. Given the Grand Wagoneer's 6,000+ lb curb weight, loss of power steering assist makes the vehicle extremely difficult to control, especially at low speeds. Stellantis issued recall 23V-635 for certain VINs related to steering rack fastener torque, but the EPS motor failure is a separate concern.
