2. NO Refer to «Checking the wiring»(ref-431021-S36383266462011101900000)

Checking the data cable

HINT: The wiring between upper electronic module (UEM) and the rain sensor consists of two cables.

The upper electronic module (UEM) transmits pulses to the rain sensor using the data cable.

Disconnect the rain sensor.

Check that the data is transmitted on the data cable terminal #1 by checking the voltage level between the data and ground cables for the wiring (that is terminals #1 and #2).

HINT: Use the oscilloscope function and check that a pulsed signal is transmitted. The difference between the high and low values of the pulses is approximately 12 V. In the event of an open-circuit in the data cable no pulses are transmitted and a continuous voltage is displayed.

If the difference between high and low values of the pulses is between 2 V and 10 V it indicates that the wiring is oxidized or trapped. Replace the wiring between the rain sensor and the roof wiring in the event of a fault.

If no other fault is found try replacing the rain sensor.

Remedy as necessary.

1. Ignition off. If no other fault is found, try replacing the rain sensor. Other information See «Rain sensor»(ref-431006-S36613426452011101900000)

1. Continue Refer to «Verification»(ref-431021-S33557726342011101900000)

Note. After carrying out the repair, check that the fault has been remedied.

1. Ignition off
2. Reinstall the connectors, components etc.
3. Ignition on
4. Activate the rain sensor. HINT: The wiper blades make a reference stroke to determine the cleanliness and condition of the windshield when the rain sensor is activated. The rain sensor is deactivated when the ignition is switched off. To reactivate the rain sensor with the ignition on, move the lever to position 0 and then to intermittent wiping. Spray water on the windshield where the rain sensor is positioned. The wiper blades must now wipe the windshield clean.

Is the rain sensor functioning?

1. YES VERIFIED: Troubleshooting has been completed.
2. NO Refer to «Information»(ref-431021-S35090718322011101900000)

See Internal fault

1. Ignition on
2. Activate the rain sensor. HINT: The wiper blades make a reference stroke to determine the cleanliness and condition of the windshield when the rain sensor is activated. The rain sensor is deactivated when the ignition is switched off. To reactivate the rain sensor with the ignition on, move the stalk to position "0" and then to intermittent wiping. Spray water on the windshield where the rain sensor is positioned. The wiper blades must now wipe the windshield clean. HINT: In cars equipped with the rain sensor it replaces the intermittent function. One way of checking the function of the rain sensor is to twist the collar on the lever. This changes the sensitivity of the rain sensor. The windshield wiper should make one stroke. If the intermittent or high speed functions are activated it indicates that the rain sensor function is missing.

1. Ignition on. Each tire pressure sensor has its own ID number and battery voltage status, which are sent to and stored in the Upper electronic module (UEM) Read out the ID numbers for the tire pressure sensors by clicking on the VCT2000 symbol. Use the following special tools to activate the sensor. «9512987»(ref-403953-S35674831992011061500000) The special tool activates the sensor, which then starts to send information to the Upper Electronic Module (UEM). After activating a sensor, press the "Show data" button for the relevant wheel. Repeat activation for all wheels. Different ID numbers should appear. If the same ID number is displayed as for the previous wheel, activation has failed. Then activate the relevant wheel again and press the "Show data" button again. NOTE: Do not forget to press the correct button after each wheel has been activated. NOTE: Make sure no special tools lie under the edge of the rim against the tire where the sensor is installed. Activation will not happen if the tool is placed next to the rim. The tool must then be kept in position for 5 seconds for the signals to be received correctly. Use only one special tool at a time in the vicinity of the vehicle. NOTE: Avoid positioning the vehicle close to other moving vehicles, the receiver may then receive signals from the sensors of these vehicles. The incorrect ID number may then appear. Then read off the ID number that is stored for the relevant diagnostic trouble code, by clicking on the diagnostic trouble code in the list. The ID number is then displayed in the window above the list. Compare the read-out ID number for the relevant wheel with the ID number that is stored with the DTC. If a sensor does not respond during the test: Replace the tire pressure sensor for the relevant wheel. It is probably the sensor that caused the DTC to be stored. If all sensors respond: The sensor that caused the diagnostic trouble code to be stored has probably had an intermittent malfunction. Replace the tire pressure sensor for the relevant wheel.

2. NO OKAY: Troubleshooting has been completed.

Checking the tire pressure sensors

1. Ignition on. Each tire pressure sensor has its own ID number which is transmitted to and stored in the upper electronic module (UEM). Read off the last stored ID number by clicking on the VCT2000 symbol. The last stored ID number is displayed until a new ID number is received and stored. NOTE: The last stored value is erased when the ignition is switched off and on again. Activate one of the sensors by using the special tool: «9512987»(ref-403953-S35674831992011061500000) The special tool activates the sensor which then starts to send information to the Upper electronic module (UEM) and the sensor's id-number can then be read in the character window. NOTE: Ensure that the special tool is positioned under the edge of the rim against the tire where the sensor is installed. The sensor will not be activated if the tool is against the rim. The sensor must then be held in place for approximately 5 seconds for the signals to be correctly received. Use only one special tool at a time in the vicinity of the car. NOTE: Carry out the above in an area away from where other cars are being driven. The receiver can pick up signals from sensors on other cars. An incorrect ID number would then be displayed. Repeat this procedure for each wheel. Different ID numbers must be displayed. If a sensor does not respond during the test: Check that a tire pressure sensor is installed on the rim. Install a new sensor if there is no sensor installed. If the sensor is installed but is still not working, it may be defective or be a sensor intended for another make or model. Replace the tire pressure sensor. If all sensors respond: Intermittent fault. The control module has previously detected that one or more sensors are not communicating. This may be because the vehicle previously had a wheel mounted without a functioning sensor.
