and joint connector (1) connector C-101 (terminal No. 3).
NOTE: Also check intermediate connector C-24 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-24 is damaged, repair or 
replace the damaged component(s) as described in GROUP 
00E, Harness Connector Inspection 

P.00E-2
