HINT: Go to the last page of each section of the TEWD and look for the illustration above among the connector diagrams.
NOTE: Connectors Marked in RED may not be employed in this vehicle.
E1 is ,more specifically,
the TCCS' Computer ground (BTW, E2 is the TCCS' sensor ground). +B
and +B1 are both 12v supplies from the EFI main relay. VF1 represents
the TCCS' VF
diagnostic signal (this operates in 3 different modes), FP is a
test feed
to the fuel pump (bypasses protection circuitry and the relay and
resistor pack)..... yada, yada, yoda....
How you use the
diagnostic block varies from one circuit to the next. The TSRM and
TEWD cover when and how to test each circuit.
