C0900 does not appear in the publicly available J2012 code lists, and no carmaker publishes it for tire pressure monitoring. The one official mention points elsewhere: GM upfitter bulletin 80C for the 2008-2014 Silverado and Sierra HD chassis cab lists C0900 subcode 07 as Device Voltage High, a supply fault logged by the PTO module. The title instead means the battery inside the first wheel transmitter. A Schrader patent describes a single lithium cell and spare function bits in every radio word that can carry a low battery message. Mitsubishi books exactly this case for tire 1 as C1910 and names the cell built into the transmitter as the likely cause. Expect the TPMS lamp; the unit is replaced and its ID registered again.

Likely causes

Built-in lithium cell of the wheel transmitter at end of life
Aged cell whose voltage sags in cold weather
On GM vehicles the code may instead stem from excessive module supply voltage (Device Voltage High)

Symptoms

  • TPMS warning lamp flashes after start, then stays lit
  • Pressure reading for one wheel drops out intermittently, more often in cold weather

Repair estimate
