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.
To test the temperature sensor
IMPORTANT:
itself, refer to Engine Temperature Sensor Test
on p. 134.
