1. Wire harness
S Check the wire harness for continuity.
Refer to "CIRCUIT DIAGRAM".
S Is the wire harness OK?
YES
2. Decompression solenoid (thermistor)
S Disconnect the decompression solenoid
couplers from the wire harness.
S Connect the pocket tester (Ω
decompression solenoid coupler as shown.

SELF-DIAGNOSIS
S Measure the decompression solenoid resis-
tance.

resistance (thermistor)
68.75
NOTE:
The resistance value for the thermistor
changes when the temperature changes;
therefore, measure the decompression sole-
noid resistance at the specified temperature.
S Connect the pocket tester (Ω
compression solenoid coupler as shown.
