ENGINE AND EMISSION CONTROL SYSTEM 6E-19
STEP ACTION YES NO
5 Main relay circuit check:
1) Install main relay.
2) Measure voltage from “A7” terminal of ECM
connector to ground.
Is voltage within 10-14V?
Go to Step 6. “B/G” wire open.
6 ECM power circuit check:
1) Connect jumper wire from “A7” terminal of ECM
connector to ground.
2) Measure voltage from “A1” terminal of ECM
connector to ground and from “A2” terminal of
ECM connector to ground.
Is each voltage within 10-14V?
Go to Step 7. “B/R” wire open.
7 ECM ground circuit check:
1) Check for continuity from “B8” terminal of ECM
connector to ground, from “B9” terminal of ECM
connector to ground and from “B17” terminal of
ECM connector to ground.
Are there continuity?
Poor connection of ECM
connector.
If OK, substitute a
known-good ECM and
recheck.
“B” or “B/Bl” wire open.
