HI,

Grand Caravan 2008 SE 80 000 KM.

ABS EPS/BAS Warning light on. COdes : C102A C1027 C1048

Reset the codes and only C102A stay.

Where should i start with all this ?
Please help and thanks in advance.

 

All three of those systems use the wheel sensors as a reference and all three codes point to the left rear wheel speed sensor and or it's circuit. All I can say is do a visual inspection on it. Might be staring you in the face. Zero experience with the system.

C102A-LEFT REAR WHEEL SPEED COMPARATIVE PERFORMANCE

 

I 2nd that. Inspect the sensor and all connection. you may want to start ohm testing the circuit.

 

what you mean by ohm?

 

Ohm is a measurement of resistance in a circuit. What he is saying is using the "ohms/resistance" function of a multimeter, measure the resistance of the wires that connect the sensor to the rest of the circuit and the resistance of the sensor itself. You should see zero or near zero ohms of resistance when checking the wires. If you see more than that there is resistance in the wire that shouldn't be there. The sensor will show some resistance. If it shows you have an open circuit through the sensor meaning infinite resistance, then you found the problem.

 

Ok thanks guys.

I found a youtube video showing me how to do it and i got a friend that is electrician and that always repair his own car so i check that with him next week.
