keja electric is the biggest electricity distribution network in Nigeria. They provide prepaid meters with the help of the meter asset providers to homes and companies in major part of Lagos.
Majority of the prepaid meters displays errors that can be fixed by the customers. Some of the errors may require the input of a trained technician. There are also shortcodes attributes to each meter that customers can use to display relevant information. For example, a customer can use a shortcode to display the last token input entered on a meter. Sometimes a step like this is necessary to confirm if the last token entered by the customer actually registered on the prepaid meter.
When your meter displays any of the error codes, you can simply call the Ikeja electric customer care lines or you can try to identify the problem and see if it is something you can fix yourself.
The error codes are different depending on the meter type you have in your home or office.
Here is a list of prepaid meters customers recharge online and supplied by Ikeja electric and some of the basic error codes and troubleshooting defaults.
Please not that if the error is not something you can fix, it is advisable that you call in a trained technician to resolve any of the problems.

Sometimes, the meter can automatically disconnects and trip. Some of the individual trip events recorded in the meter include the following
1. Credit trip: Automatic reconnection by entering a new credit token.
2. Tamper: Automatic reconnection by entering a clear tamper token.
3. Thermal Overload: Manual or automatic reconnection, depending on the configuration set at the time of production.
4. Current Overload: Manual or automatic reconnection, depending on the configuration set at the time of production.
5. Power Overload: Manual or automatic reconnection, depending on the configuration set at the time of production.
6. Credit load trip: Manual or automatic reconnection, depending on the configuration set at the time of production.
7. Scheduled load restriction Overload: Manual or automatic reconnection, depending on the configuration set at the time of production.
8. Critical load restriction overload: Manual or automatic reconnection, depending on the configuration set at the time of production.
9. Under voltage: Manual or automatic reconnection, depending on the configuration set at the time of production.
To find reasons for the last disconnect you can punch different code as seen below.
This short code will display the last abnormal trip event that caused the consumer’s load to be disconnected.
Power overload , Current over load, Thermal overload, Over voltage, Under voltage, Line/load reversal, The meter has run out of allocated consumption (over consumption).
This shortcode is used to reconnect a consumer's supply, where manual reconnection is required.
Consumers can also hold the # key for three seconds.
This follows a reconnection process where the consumer's supply is only reconnected 30 seconds after a trip event occurs.
If a valid trip condition exists, the five 30 second reconnection attempts followed by the 30-minute lockout cycle, repeat indefinitely.
Timed reconnection occurs with the following trip conditions:
1. Power overload
2. Current overload
3. Thermal overload
4. Over voltage
5. Under voltage
6. Line/load reversal
7. Consumption restriction
A consumer can manually disconnect the electricity supply using this function if it is permitted by the utility company i.e Ikeja electric in this case. Sometimes this function is permitted to allow the consumer to cut the power off in case of electricity surge. The picture below shows the display when the code is permitted and when it is not permitted.
Sometimes errors are not limited to the meter connectivity, but also the tokens entered by customers to recharge their prepaid meters. Some of the token errors are highlighted below.
This occurs when the authentication of a token fails.
The meter serial number on the token doesn’t match the physical meter number on the meter.
The tariff index on the token is not the same as the tariff index programmed into the meter.
The supply group code that the token was made on differs to the supply group code in the meter.
The key revision number of the token differs to the key revision number as programmed into the meter.
The token was entered into the meter incorrectly.
1. Check the printout of the token.
2. Run #030# for the supply group code (SGC).
3. Run #006# for the tariff index.
4. All the information should be validated to determine why the token didn’t work.
This occurs when a token is entered incorrectly or is not valid, and the meter automatically locks out for a period of time.
The token entered is incorrect or invalid.
The remaining lockout time is displayed. Once this time is complete, enter a valid token.
This occurs when a token has the same ID as a token already entered.
Same token used
Enter a valid token. You can discard this token as it is not valid.
This occurs when the credit loaded from a token takes the credit balance over the maximum amount permitted for the meter.
The meter cannot accept more credit than the maximum credit limit.
The credit associated with the token is not loaded onto the meter. You can use the token at another time.
This occurs when a token has an ID older than the oldest token loaded on the meter.
This token has expired and is too old to be loaded on the meter.
Enter a valid token. You can discard this token as it is not valid.
This occurs when the token is accepted by the meter but cannot be processed.
Break in network
Please try again
This occurs when the meter decoder key has expired.
The unique meter key has expired and this meter cannot accept tokens.
The utility company or ikeja electric in this case must change the meter key by entering a key change token.
This occurs when the terminal cover is not fitted correctly.
This may be due to the incorrect installation of the terminal cover during meter commissioning, or when entering a clear tamper token.
Commissioning: install the terminal cover and repeat the commissioning procedure.
Tamper: install the tamper cover correctly and re-enter the clear tamper token.
This occurs when the value displayed is greater than the maximum display area of the screen.
There are some codes that are standard on all of this particular prepaid meter type.
The STS dispenser test token is a non-meter specific code, used to perform a series of tests on the meter.
The test continues to step through the sequence automatically, briefly displaying the data shown for each step.
To perform this test, enter the following 20 digit token:
5649 3153 7254 5031 3471 (Please confirm with you DISCO)
To view a specific item, simply enter the relevant shortcode. For example #006# to view the tariff index.
