C2510

DTC C2510 TREAD LAMP SHORT TO 12 V

COMPONENT LOCATION:





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.
[Turn the TREAD indicator lamp off]
1. Indicates that tire needs to be re-inflated to placard pressure / repaired.
2. Under-inflation: When tire pressure is above (warning threshold + hysteresis).
3. 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)/ DTC Warning lamp is short circuit and therefore cannot be turned on. The most likely failure is harness / instrument cluster / connector / receiver short circuit.

DTC DETECTING CONDITION:





TERMINAL AND CONNECTOR INSPECTION
Refer to DTC C1126. C1126

CONTROL CIRCUIT INSPECTION
1. Engine "OFF".
2. Disconnect instrument cluster connector and TPM receiver connector.
3. Engine "ON".
4. Measure voltage between terminal "16" of TPMS receiver harness connector and chassis ground.





5. Is the measured voltage within specifications?
YES
> Substitute with a known-good TPM receiver and check for proper operation.
> If the problem is corrected, replace TPM receiver and then go to "Verification of Vehicle Repair" procedure.
NO
> Check for short to power in control harness.
> Repair if necessary and then go to "Verification of Vehicle Repair" procedure.

VERIFICATION OF VEHICLE REPAIR
Refer to DTC C1121. C1121
