Fixing the dash on the fiesta

Can I ask is anyone using the Bosch MTS 6531 pass through tool .

Gents… I’ll be honest, I’m sure plenty of others have done this too Volvo XC70 in with front and rear screenwash inoperative. One of our techs unplugged the washer pump connector ready for me to test powers and grounds. No activation to the pump, so I pulled wiring diagrams from Alldata and checked the BCM connector locations. According to the diagram, with the circuit inactive both pins at the washer pump should have a ground path. Tested it… one wire had no earth path. “Perfect” — wiring fault confirmed. Glovebox out, BCM accessed, checked the same two wires directly at the BCM… both grounds present there 🤔 At this point I’m thinking:“If there’s a break or corrosion, it’ll be under the bonnet or around the wheel arch.” So off comes the inner arch… Found the issue straight away. The tech had unplugged the washer LEVEL sensor… not the washer pump 😂 Power and Ground present Faulty washer pump all along. Moral of the story:Before reaching for the wiring diagrams… make sure you’re testing the right component first and never trust other techs working with you 😅
