   Your reasoning appears sound. Of course, this is the type of problem   
   that may not reappear, leaving you clueless as to whether all the   
   fooling around did any good or not. And, you're probably inadvertently   
   erasing any codes. But, what else can you do?  How much more trouble   
   would it have been to include OBDII scan and clear functions in the   
   operating controls of the vehicle (not requiring the acquisition and use   
   of a scan tool)?   
      
   I say optional ABS, since my '98 Tacoma does NOT have ABS, nor the   
   automatic locking front differential. 4Runners may have had ABS standard.   
      
   Does the ABS controller store codes?
