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. 125.

LOW OIL Circuit Test

Turn the key switch ON. Using a jumper wire, con-
nect tan/black wire (pin 4) of the engine harness
connector to a clean engine ground. The LOW
OIL light should turn on after 40 seconds.
If the LOW OIL light does not turn on after con-
necting the terminal to ground, test circuit for con-
002079
tinuity.
Turn the key switch OFF and reconnect all discon-
nected circuits.

NO OIL Circuit

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/yellow wire (pin
5) to a clean engine ground.
Turn the key switch ON. After the normal self-test
sequence, the NO OIL light should stay on.
•
If the NO OIL light is not on, test circuit for conti-
nuity. Test for continuity of the MWS instrument
harness (tan/yellow wire).
•
Test for continuity of the engine wire harness
between terminal 5 (tan/yellow wire) of the Sys-
temCheck connector and pin 24 of the EMM J1-
A connector.
Turn the key switch OFF and reconnect all discon-
nected circuits.
