Hi,
My name is OZ. I was reading in the forum and found out a problem similar to my car 1995 Volvo 960 back in 2010. My car has the blinking arrow and WSE lights. My speedometer works with no problem yet I get these fault codes (similar to yours back then): A1 124 (short circuit to ground in WSE), A1 232 (speedometer signal missing), and A3 155 (missing speed signal). I have checked the rear diff speed sensor and the wires and nothing wrong with them. I changed the WSE switch, PNP and same problem. I was wondering if you had managed to solve this mystery?
Thanks in advance
