I've got an 89 FJ62 and for the past few weeks I've had issues with code 21 :/
At first this happened whilst accelerating (either from a complete stop OR an an engine restart). Eventually that behavior went away - and transitioned to happening every other time I restart the engine immediately...
-right off the bat: I know about the fuse under the fuse box area and I know about the pair of relays around the rear washer fluid reservoir - neither of these things are the cause of my problems.
this is an 89 FJ62; I'm trying to understand why the only power lock that works is the driver's...
