Idle Speed Control - Specifications Update

87mitsubishi03

SUBJECT:

ISC SPECIFICATIONS - SERVICE MANUAL UPDATE
NO. STB-87-14-004
DATE March 1987

MODEL 1985-6 Tredia/Cordia
STB Revision STB-87-14-004


PURPOSE

This bulletin corrects the specifications and procedure for checking the resistance of the ISC Servo Motor on 1985 and 1986 Cordia/Tredia models equipped with feedback carburetor. Details of the change are shown in the illustration below. As reference to this bulletin, please write the STB number in the revision box on Page 14-38 in the 1985 Tredia/Cordia Service Manual and Page 14-43 in the 1986 Tredia/Cordia Service Manual.



REVISION

The ISC Servo description in the 1985 and 1986 Service Manuals are identical, even though the page numbers are different. Please change the number of the test terminals in the ISC Servo connector:
the resistance should be measured across terminals 1 and 5, not 1 and 4 as shown in the Manual. Also, the resistance value should be 5-35 ohms at room temperature, not 7-10 ohms as originally specified. And finally, change the words "injection mixer body" to "carburetor float chamber cover".
