DTC 83

CIRCUIT DIAGRAM





INSPECTION PROCEDURE

CIRCUIT DESCRIPTION:
The Electronic Brake Control Module (EBCM) and the Engine Control Module (ECM) are connected through CKT "P/W". If an open or short to battery occurs in CKT "P/W", the EBCM is unable to signal the ECM to increase engine speed. If a short to ground occurs in CKT "P/W", the ECM will receive a false signal and will raise engine's idle speed constantly.

FAILURE CONDITION:
DTC 83 can be set anytime only when the EBCM detects an open or short to ground in CKT "P/W". The EBCM will set DTC 83 due to a short to battery in CKT "P/W" only when idle-up command is active.
