9-3-2 ECU CONNECTOR VOLTAGE
(Main Circuit)
1 . Turn on the main switch . (Do not start engine .)
2 . Measure the voltage between terminal
9
(+)and
terminal
10
(-) .
3 . It is OK if the voltage equals to the battery voltage .
(Sensor Voltage)
1 . Turn on the main switch . (Do not start engine .)
2 . Measure the voltage between terminal
116
(+)and
terminal
117
(-) .
3 . It is OK if the voltage is approx . 5 V .
9-3-3 WIRING HARNESS OF ENGINE CASE
TEMPERATURE SENSOR
1 . Disconnect the engine case temperature sensor
connector (2P) .
2 . Check the state of the harness and if it is abnormal,
replace it .
3 . Turn the key switch to the
ON
position .
4 . Measure the voltage between the terminals of the
connector with voltage range of circuit tester .
5 . When the measurements are the table value below,
the ECU is normal .
The engine case temperature sensor is damaged,
then replace it .
6 . When the measurements are out of the table value
below, the ECU is failure, then replace it .
