NOTE:
  • Only an A/C control head -E87- identified with index "C" should be installed or will be installed (this version of -E87- can control a Nippondenso A/C compressor without speed sensor -G111-).
  • If a new A/C control head -E87- is installed and it is not coded, the display of -E87- blinks (after the ignition is switched on).
  • For assignment of A/C control head -E87-
  • All illegal codings are suppressed by A/C control head -E87- and the coding: 00062, 6-cylinder engine USA is stored.
  • If another code has been entered other than listed above, compressor will run a short time (shut off immediately).
