If you pull up the lock or open with then handle all the doors will unlock. The IR remote will cause the green light in the mirror to flash. The outside turn signals flash too. But the locks won’t unlock. From the SDS 38 pin connector we get a code 20 fault which is “no ground at actuator S47 which is the left front door actuator. But all grounds st actuator are good. Any idea what to do? We tried to reprogram the key with no luck. Any ideas? My mechanic is stumped. The drive authorization module needed to be replaced bc it was damaged while trying to remove ignition lock. There was an electrical short caused somehow when the ignition switch came apart. Now after reinstalling and connecting everything the locks won’t unlock. Car starts fine. Any help? Edited by ccr2002 2/1/2019 2:20 PM | ||

From my research, it is the culprit most of the time when locking doesn't work. Generally diagnosis is a pretty simple thing to do. Cheers, Gerry | ||

I think WHEN has happened. ...other spares: MAF, K40 (2001 and earlier 463), CPS, TPS. The CPS is the only tricky one tool wise. Edited by J.R. 2/4/2019 10:09 PM | ||
