IGNITION COIL INPUT VOLTAGE TEST
1. VIOLET/BLUE wire
2. BROWN/ORANGE wire
If you did not read battery voltage at the
VIOLET/BLUE wire terminal, check continuity
of the ignition coil input circuit (VIOLET/BLUE
wire to injector/ignition fuse).
If you did not read battery voltage at the
BROWN/ORANGE wire terminal, carry out a
resistance test of the ignition coil.
If battery voltage was read at both terminals, dis-
connect the ECM connector and test for continuity
of the ignition coil ground circuit.
Ignition Coil Ground Circuit
Continuity Test
Disconnect ECM connector.

Install the ECM connector onto the ECM adapter
tool (P/N 529 036 085).

TYPICAL – ECM ADAPTER TOOL INSTALLATION
1. ECM connector
2. Adapter tool
Pull back the plastic connector housing on the
BROWN/ORANGE wire of each coil enough to ac-
cess the metal terminals.
