Hyundai i-30: ESP (Electronic Stability Program) System / Troubleshooting
1. |
In principle, ESP and TCS controls are prohibited in case of ABS failure.
|
2. |
When ESP or TCS fails, only the failed system control is prohibited.
|
3. |
However, when the solenoid valve relay should be turned off in case
of ESP failure, refer to the ABS fail-safe.
|
4. |
Information on ABS fail-safe is identical to the fail-safe in systems
where ESP is not installed.
|
Memory of Fail Code
1. |
It keeps the code as far as the backup lamp power is connected. (O)
|
2. |
It keeps the code as long as the HCU power is on. (X)
|
Failure Checkup
1. |
Initial checkup is performed immediately after the HECU power on.
|
2. |
Valve relay checkup is performed immediately after the IG2 ON.
|
3. |
It executes the checkup all the time while the IG2 power is on.
|
4. |
Initial checkup is made in the following cases.
(1) |
When no failure is detected
|
(2) |
When ABS and ESP are not in control.
|
(3) |
Initial checkup is not made after ECU power on.
|
(4) |
If the vehicle speed is over 5 mph(8 km/h) when the brake lamp
switch is off.
|
(5) |
When the vehicle speed is over 24.8 mph(40 km/h).
|
|
5. |
Though, it keeps on checkup even if the brake lamp switch is on.
|
6. |
When performing ABS or ESP control before the initial checkup, stop
the initial checkup and wait for the HECU power input again.
|
7. |
Judge failure in the following cases.
(1) |
When the power is normal.
|
(2) |
From the point in which the vehicle speed reaches 4.9 mph(8
km/h) after HECU power on.
|
|
Countermeasures In Fail
1. |
Shut the system down and perform the following actions and wait for
HECU power OFF.
|
2. |
Turn the valve relay off.
|
3. |
Do not perform any ABS/TCS/ESP functions until normal operating condition
is restored.
|
Warning Lamp ON
1. |
ABS warning lamp turns on when ABS is malfunctioning.
|
2. |
ESP function/ warning lamp turns on when ESP is malfunctioning.
|
When power voltage and valve relay voltage are abnormal, input/output related
failure judgment is not made.
