If no open circuit can be detected, check sensor plug, pin 1 to pin 4
and pin 1 to pin 2, for continuityusing an ohmmeter. There should be
no continuity.
If no short circuit can be detected, replace sensor,
Test point 3
Inner left sensor faulty This fault is stored in the memory in the following cases:
Fault code 3 1. Open circuit in supply lead to inner left sensor.
2. Short circuit to B+ in supply lead to inner left sensor.
3. Short circuit to ground in supply lead to inner left sensor.
Remedy:
Erase fault memory, move shift lever out of reverse gear and switch
off ignition. Next, switch ignition back on, move shift lever into reverse
and read out fault memory.
If the fault reappears, check the plug on the sensor for open
circuit.
If no open circuit can be detected, check sensor plug, pin 1 to pin 4
and pin 1 to pin 2, for continuityusing an ohmmeter. There should be
no continuity.
If no short circuit can be detected, replace sensor.
Test point 4
Outer left sensor faulty This fault is stored in the memory in the following cases:
Fault code 4 1. Open circuit in supply lead to outer left sensor.
2. Short circuit to B+ in supply lead to outer left sensor.
3. Short circuit to ground in supply lead to outer left sensor.
