Toyota Tacoma 2015-2018 Service Manual: Engine Coolant Temperature Receiver Gauge Malfunction

Toyota Tacoma 2015-2018 Service Manual / Meter / Gauge / Display / Meter / Gauge System / Engine Coolant Temperature Receiver Gauge Malfunction

DESCRIPTION

In this circuit, the meter CPU receives engine coolant temperature signals from the ECM using the CAN communication system (CAN V1 Bus). The meter CPU displays engine coolant temperature that is calculated based on the data received from the ECM.

CAUTION / NOTICE / HINT

CAUTION / NOTICE / HINT

HINT:

If there is an open or short in the engine coolant temperature sensor circuit, the ECM stores the DTCs. Troubleshoot the SFI System (for 2TR-FE) (See page ) . ) or SFI System (for 2GR-FKS) (See page PROCEDURE ) .

PROCEDURE

1.

CHECK CAN COMMUNICATION SYSTEM

(a) Check if a CAN communication DTC is output (See page Result Result ).

READ VALUE USING TECHSTREAM (COOLANT TEMPERATURE)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Combination Meter / Data List.

(e) According to the display on the Techstream, read the Data List.
