Toyota Tacoma (2015-2018) Service Manual: Dtc Check / Clear
DTC CHECK / CLEAR
HINT:
- DTCs which are stored in the ECM can be displayed on the Techstream.
- The Techstream can display pending DTCs and current DTCs. Some DTCs are not stored unless a malfunction is detected in consecutive driving cycles. When a malfunction is detected in only one driving cycle, it is stored as a pending DTC.
1. CHECK DTC (Using Techstream)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Transmission / Trouble Codes.
(e) Check for DTCs and freeze frame data, and write them down.

Techstream Display |
Description |
|---|---|
|
Test Failed |
Shows the malfunction judgment results for the current trip. |
|
Pending |
Shows the malfunction judgment results from when the DTCs were last cleared up until they were checked. (Indicates the possibility of a malfunction when no DTCs are confirmed.) |
|
Confirmed |
Shows the DTCs confirmed up to now. (The number of current trips differs for each DTC.) |
(f) Check the details of the DTCs (See page .gif)
).
NOTICE:
When simulating a symptom and using the Techstream to check for DTCs, use normal mode. For DTCs in the Diagnostic Trouble Code Chart subject to "2 trip detection logic", perform the following:
Turn the ignition switch off after the symptom is simulated once. Then repeat the simulation process. When the symptom has been simulated twice, the MIL will illuminate and DTCs will be stored in the ECM.
2. CLEAR DTC (When Using Techstream)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Transmission / Clear DTCs.
(e) Clear the DTCs.
3. CLEAR DTC (When not Using Techstream)
(a) Perform either of the following operations:
NOTICE:
After turning ignition switch off, waiting time may be required before disconnecting
the cable from the negative (-) battery terminal. Therefore, make sure to read the
disconnecting the cable from the negative (-) battery terminal notices before proceeding
with work (See page ).
(1) Disconnect the cable from the negative (-) battery terminal for more than 1 minute.
(2) Remove the EFI NO. 1 and ETCS fuses from the engine room relay block, located inside the engine compartment, for more than 1 minute.

1. DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful because intermittent conditions or signals ...
Steering Angle Sensor Internal Circuit (C1433)
DESCRIPTION
Steering angle sensor (spiral cable with sensor sub-assembly) signals are sent
to the skid control ECU (master cylinder solenoid) via the CAN communication system.
When there is a malfunction in the CAN communication system, it is detected by the
steering angle sensor (spiral cabl ...
Short in Side Squib LH Circuit (B1825/56-B1828/56)
DESCRIPTION
The side squib LH circuit consists of the airbag sensor assembly and the front
seat airbag assembly LH.
This circuit signals the SRS to deploy when airbag deployment conditions are
met.
These DTCs are set when a malfunction is detected in the side squib LH circuit.
