Tire Pressure Monitoring System

Fault Code 1474

Antenna for monitoring tire pressure, rear left

NOTE: Systems with a transmission frequency of 315 MHz are installed in vehicles for Asian and Arab countries for legal reasons. The wheel electronics and the antenna can be identified by the light grey color. The components must not be interchanged with components from the other 433 MHz systems.

Diagnostic conditions

- Ignition on
- Control module for tire pressure monitoring system, internal function test

Possible cause of fault

- Wiring for rear left antenna faulty (open circuit and/or short circuit)
- Rear left antenna faulty

Affected pins

Control module plug:
- Pin 9 'antenna RL 1'
- Pin 25 'antenna RL 2'
- Pin 8 'Ground RL'

Diagnosis/troubleshooting

NOTE: The resistance of the antenna cannot be reliably measured in antennae of the 315 MHz variety (light grey color).
