Study Guide and Component Location

clip_image004

Study Guide and General Description

Study The normal operating temperature of the HO2S(Heated Oxygen Sensor) ranges from 350 to 850°C(662 to 1562°F). Study The HO2S heater greatly decreases the amount of time required for fuel control to become active. Study The ECM provides a pulse width modulated control circuit to adjust current through the heater. When the HO2S is cold, the value of the resistance is low and the current in the circuit is high. Study On the contrary, if the temperature in the resistor of the sensor rises, the current drops gradually.

Study Guide and DTC Description

Study If the sensor output is below 0.06 V under enable conditions, ECM sets DTC P0131.

( This DTC might be caused by the malfunction of Heater circuit, so, check the heater circuit first. )

Study Guide The signal waveforms of front HO2S(the lower) and heater(the upper) at idle

Study The output voltage of front HO2S is changed continuously accroding to air/fuel ratio, ECM controls fuel amount based on this value. Preheating is necessary for HO2S normal operation. Study Therefore heater unit is installed in HO2S, ECM can control air/fuel ratio with the output signal of HO2S simultaneous with engine run by reducing preheating time. Study ECM controls heater with duty cycle. Study HO2S' power source is main relay and ECM operates heater by ground control.

Study Guide and Component Location

clip_image004

Study Guide and General Description

Study The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the intake camshaft. Study This system controls the intake camshaft to provide the optimal valve timing for every driving condition. Study The ECM controls the Oil Control Valve(OCV), based on the signals output from mass air flow, throttle position and engine coolant temperature. Study The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease under overall driving conditions.

Study Guide and DTC Description

If there is a delay between the target angle and the real angle over 5 times,ECM sets DTC P0024.

Displacement: 2400cc

How to Repair Shift Shock,Brake,Airbag Indicator On.

1) Study Guide and Condition

  • Study Engine pre start not functioning.
    = If the Smart Key will not put to PIC holder  the starting system totally black out.
  • Study Automatic Transmission Shift Shock.
  • Study Shift Lever Solenoid Malfunctioning.
  • Study Airbag Indicator Always On.
  • Foot Brake Indicator Always On.
  • Study GDS Communication fail.

2) Study Guide and Cause

  1. Study If the Smart Key will not put to PIC holder  the starting system totally black out Due to the RF receiver fuse loose contact.
  2. Study GDS Communication fail, Airbag, Foot Brake, ESP Indicator Lights On Due to Airbag Module Terminal Ground. poor contact to body.

3) Study Guide and Trouble Diagnosis

  1. Study Check with the GDS but fail. Since the engine not cracking if the smart key will not put to PIC Holder first option to think is to check the fuses.OK
  2. Study Check with Good Smart Key Module and PDM(Power Distribution Module. But Still the same.
  3. Study Check the RF receiver battery + terminal = No power. i will go to the socket connector but ok for the 2nd time check again the RF fuse ,found out that there is poor contact. Repair so the starting system problem now OK.
  4. Study 2nd problem is GDS commutation fail,indicator light on.i will go first to air bag usually i have the same trouble before that’s why i will try with good Airbag module but the problem still occurs i will  make another ground from the airbag. The indicator suddenly lights off.so the ground terminal has poor in contact,clean and retighten the ground bolt.

How to perform N position learning

If the automatic transmission or the TCU is replaced, be sure to initialize the learned values and perform N position learning.

1.

Stop the vehicle by shifting the shift lever to the P range and chock the tires. Turn the ignition switch to the ON position

Caution

Study Guide

Check that the vehicle is stationary before operation.

2.

Release the shift lock, and shift the shift lever to the N range.

3.

Check that the TCU N position mark is correct.

4.

Check that the N position is correctly displayed on the special tester.

Study Guide

Caution

The command cannot be input unless the ignition switch is on, the shift lever is in the N range, the engine is stopped, and the vehicle speed is 0 km/h.

-

Input NG is indicated: Check again that the N position mark is correct. If it is incorrect, adjust it.

-

Input OK is indicated: Turn the ignition switch off after releasing the shift lock and shift the shift lever to the P range. Turn the ignition switch on after 5 seconds.

5.

Study Shift the shift lever from the P to the D position, then check that the indicator displays the correct position.

A.

Display is correct: Check the trouble code.

B.

Display is incorrect: Perform the initial learning.

Study guide How to perform initial learning

If the automatic transmission or the TCU are replaced, or the TCU software is overwritten, be sure to initialize the learned values and perform initial learning.

1.

Study Guide and Warm-up

Study Raise the ATF temperature by leaving the vehicle idling or performing a city drive. Check the ATF temperature using the special tester and make sure it is between 66 and 110°C. If the oil temperature is outside this range, work to bring it inside the range.

Caution

Study Guide

Do not attempt to raise the oil temperature by stalling the engine.

Notice

Study Guide

Study If the oil temperature is not between 66 and 110°C, initial learning cannot be performed. Before learning, check for shift shock or variable speed shock.

2.

Study Guide and Garage shift learning

Study With the vehicle stationary, depress the brake and keep the shift lever in N for 3 seconds. Then, shift from N into D, and maintain this condition for 3 seconds. Repeat this procedure 5 times. Then repeat 5 times in the same way for R.

3.

Study Guide and Gear shift control learning

Study In D, with the throttle opening angle between 25 and 35%, drive until 6th gear and a vehicle speed of 110 km/h or higher is reached. Then, release the accelerator pedal and coast, and bring the vehicle to a stop within 60 seconds. Repeat this procedure 10 times.
