DTC CHECK / CLEAR
HINT:
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 ).
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.
SM Solenoid Circuit (C1225,C1468,C1469,C146A,C146B)
DESCRIPTION
These solenoids turn on when signals are received from the skid control ECU (brake
actuator assembly) and they control the pressure acting on the wheel cylinders to
control the braking force.

1. DESCRIPTION
The 4 wheel drive control ECU records DTCs when the ECU detects a malfunction
in the ECU itself or in system circuits.
The DTCs can be read through the DLC3 of the vehicle. When the system seems to
be malfunctioning, use the Techstream to check for malfunctions ...
Compressor Lock Sensor Circuit (B1422)
SYSTEM DESCRIPTION
The ECM sends the engine speed signal to the air conditioning amplifier assembly
via CAN communication.
The air conditioning amplifier assembly reads the difference between compressor
speed and engine speed. When the difference becomes too large, the air conditioning
ampli ...
