General Information

C2510 TREAD Lamp short to 12 V

General Information

General Description

The TPMS receiver unit must provide two outputs continuously to drive the indicator lamps. One of the output turn the TREAD indicator lamp on when pressure in one or more tires associated with the TPMS receiver unit have reported a pressure below the warning level threshold. The other output turn the TPMS Warning indicator bulb on when the TPMS receiver unit has detected a system fault.
[Turn the TREAD indicator lamp on]
1 When tire pressure is below allowed threshold.
2 When rapid leak is detected by the sensor.
3 Indicates that tire needs to be re-inflated to placard pressure / repaired.
[Turn the TREAD indicator lamp off]
1 Under-inflation : When tire pressure is above (warning threshold + hysteresis).
2 Leak : When tire pressure is above (leak warning threshold) OR on Ignition cycle off to on.

DTC Description

This DTC indicates that the TREAD (Tire Under Inflation / Leak Warning) lamp is short circuit to 12 V and therefore cannot be turned on. The most likely failure is harness / instrument cluster / connector / receiver short circuit.
