Engine Electrical System > Ignition System > Description and Operation
Descrition
Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data for
the engine operating conditions are preprogrammed in the memory of the ECM (Engine Control Module).
The engine operating conditions (speed, load, warm-up condition, etc.) are detected by the various sensors. Based on
these sensor signals and the ignition timing data, signals to interrupt the primary current are sent to the ECM. The ignition
coil is activated, and timing is controlled.

 https://www.hyundaitechinfo.com/viewer/toc_print.asp?vehic...

of alternator and the (-) lead wire of voltmeter to the (+) terminal of battery.

Test
1. Start the engine.
2. Turn on the headlamps and blower motor, and set the engine speed until the ammeter indicates 20A.
And then, read the voltmeter at this time.

Result
1. The voltmeter may indicate the standard value.

Standard value: 0.2V max

2. If the value of the voltmeter is higher than expected (above 0.2V max.), poor wiring is suspected. In this case check
the wiring from the alternator "B" terminal to the battery (+) terminal. Check for loose connections, color change due to
an over-heated harness, etc. Correct them before testing again.
3. Upon completion of the test, set the engine speed at idle.
Turn off the headlamps, blower motor and the ignition switch.

Output Current Test

This test determines whether or not the alternator gives an output current that is equivalent to the normal output.

Preparation
1. Prior to the test, check the following items and correct as necessary.
Check the battery installed in the vehicle to ensure that it is in good condition. The battery checking method is
described in the section "Battery".
The battery that is used to test the output current should be one that has been partially discharged. With a fully
charged battery, the test may not be conducted correctly due to an insufficient load.
Check the tension of the alternator drive belt. The belt tension check method is described in the section "Inspect drive
belt".
2. Turn off the ignition switch.
3. Disconnect the battery ground cable.
4. Disconnect the alternator output wire from the alternator "B" terminal.
5. Connect a DC ammeter (0 to 150A) in series between the "B" terminal and the disconnected output wire. Be sure to
connect the (-) lead wire of the ammeter to the disconnected output wire.

Tighten each connection securely, as a heavy current will flow. Do not rely on clips.

6. Connect a voltmeter (0 to 20V) between the "B" terminal and ground. Connect the (+) lead wire to the alternator "B"
terminal and (-) lead wire to a good ground.
7. Attach an engine tachometer and connect the battery ground cable.

17 of 58 19/08/12 22:41
 https://www.hyundaitechinfo.com/viewer/toc_print.asp?vehic...

8. Leave the engine hood open.

Test
1. Check to see that the voltmeter reads as the same value as the battery voltage. If the voltmeter reads 0V, and the
open circuit in the wire between alternator "B" terminal and battery (-) terminal or poor grounding is suspected.
2. Start the engine and turn on the headlamps.
3. Set the headlamps to high beam and the heater blower switch to HIGH, quickly increase the engine speed to 2,500
rpm and read the maximum output current value indicated by the ammeter.

After the engine start up, the charging current quickly drops.
Therefore, the above operation must be done quickly to read the maximum current value correctly.

Result
1. The ammeter reading must be higher than the limit value. If it is lower but the alternator output wire is in good
condition, remove the alternator from the vehicle and test it.

Limit value : 65A min.

• The maximum output current value is shown on the nameplate affixed to the alternator body.
• The output current value changes with the electrical load and the temperature of the alternator itself.
Therefore, the maximum output current may not be obtained. If such is the case, keep the headlamps on the
cause discharge of the battery, or use the lights of another vehicle to increase the electrical load.
The maximum output current may not be obtained if the temperature of the alternator itself or ambient
temperature is too high.
In such a case, reduce the temperature before testing again.

2. Upon completion of the output current test, lower the engine speed to idle and turn off the ignition switch.
3. Disconnect the battery ground cable.
4. Remove the ammeter and voltmeter and the engine tachometer.
5. Connect the alternator output wire to the alternator "B" terminal.
6. Connect the battery ground cable.

Regulated Voltage Test

The purpose of this test is to check that the electronic voltage regulator controls voltage correctly.

Preparation
1. Prior to the test, check the following items and correct if necessary.
Check that the battery installed on the vehicle is fully charged. The battery checking method is described in the
section "Battery".
Check the alternator drive belt tension. The belt tension check method is described in the section "Inspect drive belt".
2. Turn ignition switch to "OFF".

18 of 58 19/08/12 22:41
 https://www.hyundaitechinfo.com/viewer/toc_print.asp?vehic...

3. Disconnect the battery ground cable.

voltmeter to the "B" terminal of the alternator. Connect the (-) lead to good ground or the battery (-) terminal.
5. Disconnect the alternator output wire from the alternator "B" terminal.
6. Connect a DC ammeter (0 to 150A) in series between the "B" terminal and the disconnected output wire.
Connect the (-) lead wire of the ammeter to the disconnected output wire.
7. Attach the engine tachometer and connect the battery ground cable.

Test
1. Turn on the ignition switch and check to see that the voltmeter indicates the following value.

Voltage: Battery voltage

If it reads 0V, there is an open circuit in the wire between the alternator "B" terminal and the battery and the battery (-)
terminal.
2. Start the engine. Keep all lights and accessories off.
3. Run the engine at a speed of about 2,500 rpm and read the voltmeter when the alternator output current drops to 10A
or less.

Cruise Control
Cruise control system is engaged by the "ON. OFF" main switch located on right of steering wheel column. The system
has the capability to cruise, coast, resume speed, and accelerate, and raise "tap-up" or lower "tap-down" set speed.
It also has a safety interrupt, engaged upon depressing brake or shifting select lever.
The ECM is the control module for this system.
The main components of cruise control system are mode control switches, transaxle range switch, brake switch, vehicle
speed sensor, ECM and ETS motor that connect throttle body.
The ECM contains a low speed limit which will prevent system engagement below a minimum speed of 40km/h (25mph).
The operation of the controller is controlled by mode control switches located on the steering wheel.
Transaxle range switch and brake switch are provided to disengage the cruise control system. When the brake pedal is
depressed or select lever shifted, the cruise control system is electrically disengaged and the throttle is returned to the
idle position.

Engine Electrical System > Cruise Control System > P0567 Cruise Control RESUME
Signal
General Description
The cruise control system keeps the vehicle running at a fixed speed until a signal canceling this fixed speed is received.
When the main switch "AUTO CRUISE" is turned on with vehicle in the running mode, the battery voltage is applied to the
PCM. When a signal from the control switch is input to the PCM while the vehicle is in state, the cruise control actuator is
activated to operate the system the PCM controls the ETS motor to make a car go at a steady speed you want. Also,
while the system is operating, "AUTO CRUISE" indicator lamp in the meter assembly lights up. In case of the cruise
control system failure, the symptoms such as acceleration failure and vehicle speed setting failure will occur.

DTC Description
If the RESUME swich signal is switching too frequently or stuck for too long, PCM sets P0567.
