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 Volts
Sensor supply voltage display: approx. 8 Volts
- 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 Volts
Sensor supply voltage display: approx. 8 Volts
- Delete fault memory, disengage reverse gear and switch off ignition. Then switch on Ignibon, 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).
Test Point 8
TEST POINT 8
EPROm Data Faulty Or Parameter Set Not Programmed
Fault Code 8
This fault is stored in the following cases:
1. The control module is faulty.
2. The control module is not correctly programmed.
Elimination:
- 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, check that the vehicle type is correctly coded. It the coding is correct, replace control module.
