Actual value for evaluation
Engine is not warm up over approx. 65℃(149℉) and engine stop
Check items with the scantool
① Coolant temperature current data
② Check the battery voltage at the water heater 1,2,3 by using a multimeter
CURRENT DATA
To raise the temperature of the engine coolant vehicle needs the engine coolant heater controlled. by ECM additionally. For checking the wire from the fuses to the heater including the heater relays, the battery voltage should be inspected untill the water temperature is reached 65℃(149℉) by using a multimeter.
IS THERE BATTERY VOLTAGE INSPECTED ?
YES
Fault is intermittent caused by poor contact in the sensor’s and/or ECM’s connector or was repaired and ECM memory was not cleared.
Check for intermittent fault by observing the data parameter for a sudden change while wiggling the wiring and tapping lightly on the suspect component.
Be careful not to damage wires or components during the test.
Repair as necessary and go to " Verification of Vehicle Repair " procedure
NO
Go to " W/Harness Inspection " procedure.
