File in Group 8
Number 104
Corp. Ref. No. 918113
Date July, 1989
SUBJECT: SERVICE INFORMATION MANUAL UPDATE: PAGES 8A-20-3 AND 8A-20-4
MODELS AFFECTED: 1988 ELDORADOS AND SEVILLES
Page 8A-20-3 of the 1988 Eldorado and Seville Service Information Manual Final Edition incorrectly states that circuits # 435 and # 436 route to ECM pins D3 and C2 respectively.
^ Circuit # 435 should be labeled as entering the ECM to pin "C2".
^ Circuit # 436 should be labeled as entering the ECM to pin "D3".
Page 8A-20-4, included for a running production change to the grounding of the manifold air temperature and coolant temperature sensors, correctly identifies the routing of circuits # 435 and # 436.
Please note these corrections in your Service Information Manuals.
