Inspection procedure 35
Inter-cooler water spray circuit systemProbable causes of the malfunction
•If the inter-cooler water spray switch (manual) is turned ON, the inter-cooler
water spray manual ‘ON’ signal will be input in the engine ECU. When this
signal is received, the engine ECU will turn the inter-cooler water spray relay
ON, and will start the inter-cooler water spray motor. Water will be sprayed
into the inter-cooler to cool intake air, and filling efficiency will improve.
•If the inter-cooler water spray switch (auto) is turned ON, the inter-cooler
water spray auto ‘ON’ signal will be input in the engine ECU. When this
signal is received the engine ECU will intermittently run at a high load, it will
turn the inter-cooler water spray relay ON, and it will start the inter-cooler
water spray motor. Water will be sprayed into the inter-cooler to cool intake
air, and filling efficiency will improve.•Malfunction of the inter-cooler water
spray switch.
•Malfunction of the inter-cooler water
spray relay.
•Malfunction of the inter-cooler water
spray motor.
•Circuit break, short circuit or a faulty
connection in the inter-cooler water
spray relay circuit.
•Circuit break, short circuit or a faulty
connection in the inter-cooler water
spray switch circuit.
•Malfunction of the ignition switch.
•Malfunction of the engine ECU.
Replace the engine ECU
