ELECTRICAL AND IGNITION
SystemCheck CIRCUIT TESTS
the two connectors, replace
SystemCheck
gauge.
Turn the key switch OFF and reconnect all discon-
nected circuits.
CHECK ENGINE Circuit Test
Separate the 6-pin
SystemCheck
connector of
MWS instrument harness from engine harness.
Black wire (pin 3) must be grounded.
Using a jumper wire, connect tan/orange wire (pin
2) to a clean engine ground.
Turn the key switch ON. After the normal self-test
sequence, the CHECK ENGINE light should stay
on.
•
If the CHECK ENGINE light is not on, test circuit
for continuity. Check continuity of the MWS
instrument harness (tan/orange wire).
•
Check continuity of the engine wire harness
between terminal 2 (tan/orange wire) of the
SystemCheck
connector and pin 17 of the
EMM
J1-A connector.
Turn the key switch OFF and reconnect all discon-
nected circuits.
WATER TEMP/ HOT Circuit Test
The tan wire of engine harness and the MWS har-
ness receives a signal from the
EMM.
The
EMM
receives information from the temperature sensor
on the cylinder head.
Using a jumper wire, connect tan wire (pin 6) of
the engine harness connector to a clean engine
ground.
Turn the key switch ON. After the normal self-test
sequence, the gauge WATER TEMP / HOT indi-
cator should stay on.
•
If LED is not on, test circuit for continuity. Test
for continuity of both the engine harness (tan
wire) and the MWS instrument harness (tan
wire).
Turn the key switch OFF and reconnect all discon-
nected circuits.
IMPORTANT:
To test the temperature sensor
itself, refer to
Engine Temperature Sensor Test
on p. 134.
