This bulletin updates Figure A-4, Dash Harness to Engine Harness Interconnect found on page 6E-A-6. The Illustration included in the Service Manual depicts the circuit locations incorrectly. Refer to the updated illustration when diagnosing circuits in the Dash Harness to Engine Harness Interconnect.








This bulletin also updates Chart C-10A (page 1 of 3) and C-10B (Page 1 of 3) Diagnostic charts in Section 6E3, "Driveability and Emissions".

The Revised Charts specify the use of a DVM (J 39200) instead of a test light to check the A/C request circuitry between the A/C controls and the PCM. Use of the DVM for this purpose is necessary due to the low current supplied to the A/C request line by some systems.
