I found the wiring harness to have been repaired before and repaired broken insulation on several wires. Although continuity seemed healthy this did not repair the fault. I bought a replacement harness which also did not repair the fault. The latch operates by giving it a 12v pulse from the cig lighter so it does work...just not getting a signal using the remote or unlock button. Is this the CEM at fault and if so how do I get it sorted? Can the CEM be reset?
Hi
100 percent the wire in the loom is broken. Undo the harness near the hinge, solder the broken earth wire. Job done
