Inspect connectors for damage.
Is everything
OK?
Disconnect internal harness from EPC solenoid.
Connect posrtive lead from ohmmeter to EPC tester jack and
negative lead to blue wrre at EPC connector. Record resistance.
Next, connect positive lead from ohmmeter to VPWR tester
jack and negative lead at green wire at EPC connector. Record
resistance.
All resistance readings should be less than 0.5 ohms.
Is resistance less than 0.5 ohms?
10 Check for continuity between BAT
-
(engine ground) and
appropriate wire (Green+lBlue - ) with ohmmeter.
Connection should show inffnite resistance (no continuity)
