DATE: August, 1995

SUBJECT:
Section 6E3 - Driveability and Emissions - Revised EGR Connectors for DTC 75, DTC 76, DTC 77 and Revised DTC 82 Chart

MODELS:
1994-95 Chevrolet Camaro
1994-95 Pontiac Firebird
with 3.4L Engine (VIN S-RPO L32)

1994-95:
On pages 6E3-A-116, 6E3-A-118 and 6E3-A-120 the DIGITAL EGR valve connector terminals are incorrectly identified. The correct terminals and circuits are listed here:

^ CIRCUIT 698 BRN to DIGITAL EGR valve connector terminal "B"

^ CIRCUIT 699 RED to DIGITAL EGR valve connector terminal "C"

In addition, the last sentence in the CIRCUIT DESCRIPTION on page 6E3-A-120 should read solenoid # 3.

1995 Only:
On page 6E3-A-127 the DTC 82 diagnostic chart refers to circuit 430 in two places. Those circuit numbers should be changed to 647.

Step number 2 on diagnostic flow chart asks to probe harness terminals "A" & "C". They should be changed to "A" & "B".

Please make changes in appropriate 1994 and 1995 service manuals.
