Fault code 5
This fault is stored in the following cases:
1. Low vehicle voltage
2. If there is a fault in the generator
Elimination:
Examine battery and generator voltages.
Select Control module supply voltage and Sensor supply voltage under the menu item Actual values, and check the values with reverse gear engaged
and the engine running.
Control module supply voltage display approx. 12 V
Sensor supply voltage display approx. 8 V
Delete fault memory, disengage reverse gear and switch off ignition. Then switch on ignition, engage reverse gear again and read out fault memory.
Test Point 6
Test point 6
Control module supply voltage <6.5 V
Fault code 6
This fault is stored in the following cases:
1. Low vehicle voltage
2. If there is a short circuit in the supply leads
Elimination:
Examine battery and generator voltages.
Select Control module supply voltage and Sensor supply voltage under the menu item Actual values, and check the values with reverse gear engaged
and the ignition switched on.
Control module supply voltage display approx. 12 V
Sensor supply voltage display approx. 8 V
Pull out number plate light and check for continuity with an ohmmeter on the pin and sleeve side of the plug connection pin 4 towards pin 3.
Test Point 7
Test point 7
Transmission / Reception pulse
Fault code 7
This fault is stored in the following cases:
1. Low vehicle voltage
2. If there is a short circuit in the supply leads
3. Faulty sensors or a faulty control module
Elimination:
Examine battery and generator voltages.
Select Control module supply voltage and Sensor supply voltage under the menu item Actual values, and check the values with reverse gear engaged
and the ignition switched on.
Control module supply voltage display approx. 12 V
Sensor supply voltage display approx. 8 V
Delete fault memory, disengage reverse gear and switch off ignition. Then switch on ignition, engage reverse gear again and read out fault memory.
If the fault reappears and one or several sensors are detected as being faulty as well, replace sensor(s).
