instrument harness terminal 1 (purple wire) and
terminal 2 (black wire).

1. Test adapter(s)
2. Connector, SystemCheck gauge
•
If battery voltage is present, replace the gauge.
•
If there is no battery voltage, check that 12 V is
present at terminal "B" of the key switch. Check
condition of the instrument harness, key switch,
and connections.
If the lights worked, but the warning horn did not
sound for one-half second, turn the key switch
OFF. Disconnect the warning horn 2-pin connec-
tor. Substitute a known good warning horn. Turn
the key switch ON.
•
If the substitute horn beeps, the original horn is
defective and must be replaced.
•
If the substitute horn does not beep, check for
battery voltage between instrument harness 2-
pin connector, terminal 2 (purple wire) and
ground with the key switch ON. Also, check the
tan/blue wire for continuity between pin 8 of the
8-pin connector and pin 1 of the 2-pin connec-
tor.
•
If battery voltage is present at the purple wire
and the tan/blue wire has continuity between

the two connectors, replace SystemCheck
gauge.
1. Purple wire
2. Tan/blue wire
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 Sys-
temCheck 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.
