3.

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

1)

CURRENT DATA

To raise the temperature of the engine coolant, the vehicle also requires help from the ECM to control the engine coolant heater. Check the wire from the fuses to the heater, and the heater relays. Use a multimeter to monitor battery voltage untill the water temperature reachs 65.

4.

IS THERE BATTERY VOLTAGE INSPECTED ?

YES

a.

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.
