Electronic Control Module (ECM)

NOTE: For terminal ID see PIN VOLTAGE CHART S article.

The ECM is located under glove box. ECM power is sent from the EFI main relay to ECM terminals B1 and B7. ECM back-up power is received from fuse box 15-amp fuse No. 7 at ECM terminal B9.

NOTE: Components are grouped into 2 categories. The first category is INPUT DEVICES, which are components that control or produce voltage signals monitored by the control unit. The second category is OUTPUT SIGNALS  , which are components controlled by ECM.
