DTC C2511 DIAGNOSTIC LAMP SHORT TO 12 VCOMPONENT LOCATION
Refer to DTC C2510. C2510
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 TPMS DTC Warning indicator lamp on]
1. When the system detects a fault that is external to the receiver / sensor.
2. When the system detects a receiver fault.
3. When the system detects a sensor fault.
[Turn the "TPMS DTC Warning indicator lamp off]
1. If the fault is considered as "critical", then the lamp is held on throughout the current Ignition cycle (even if the DTC has been demoted). This is because it is important to bring the problem to the drivers attention. On the following Ignition cycle, the demotion conditions will be re-checked. If the demotion conditions occur, the lamp will be turned off. It will be held on until DTC demotion checking is completed.
2. 'Non critical" faults are those that can occur temporarily e.g. vehicle battery under voltage. The lamp is therefore turned off when the DTC demotion condition occurs.
