ECM - CALPAC Installation
Number 84-6 (Gasoline)-65 Date 10/84Subject: CALPAC INSTALLATION - 2000 SUNBIRD 1.8L TURBO
When Codes 51 or 55 are indicated and fuel delivery to the engine is interrupted, the ECM should be checked for a missing Calpac. Code 52 will NOT register if the Calpac is missing. If the Calpac is in place, normal diagnostics should be used to check for a malfunctioning PROM or ECM.
When servicing the ECM, both the Calpac and PROM must be transferred to the new ECM.
