Engine check light

The codes are OBD2 and are available on line, try looking for code p1613 and there will be the answer. You may have other problems as this code is not related to ABS The tire pressure is the result of a low tire or faulty pressure sensor. Check air pressure and bring to correct pressure. The TPMS may have to be rest using a specif tool. Tire shops , and dealers have them.

P1613 registered code,which points to a memory malfunction. Update cars software at the dealer. This resets it.

That would be P1611 and P1613, the letter is important as it indicates the system of the car affected, in this case the powertrain. I would unplug the large connector to the transmission and see if water has intruded into it. if so blow it out until it is dry and reinstall it. If that doesn't fix the problem you need to get a transmission repair shop involved in the diagnosis and repair.

• Check Malfunction Indicator Lamp (MIL)
• Check Wiring/Connectors from/to Malfunction Indicator Lamp (MIL)
• Check Control Module Coding
• Check/replace ignition/starter switch
• Check relay on left plenum chamber for execive wear

The P1613 is a warning for defective bulb,socket or wiring from the check engine light.

Is the CHECK ENGINE LIGHT light up when you crank the engine?

Ohm out the bulb
Check for corrosion to light sockey
Check wiring between bulb to ECU

1613 Permanent fault Programming Programming error
P1613 No fault

Find another mechanic you will not read this fault ,what you have here is a old time seat of the pants fault and to work it out you need a old timer mechanic ,now 2004 could be a fly by wire throttle and the fault could be the pedal control inside the cab ,happens a lot with renault meganes and lagunas but thats my favourite car to hate a renault --Another posibility is the fuel pump going home and to diagnose i would need to drive the car and when it stops to check for spark and fuel pressure ,simple to a old geezer like me but some of these youngsters only know how to read a diagnostic reader ,Try repairing a truck on the motorway at 03.00 in the morning in -12C if i couldnt get it going i would have been out of a job

The Engine Control Module (ECM) is in constant communication with the other control units (e.g. Transmission, Body, etc). When there is a problem with a system other than the engine control, the ECM is requested to turn the engine light ON and set the P1613 code. P1613 indicates that there one of the control module have requested the Engine Control Module (ECM) to turn ON the check engine lamp. Usually the P1613 code is combine with another code.
Generally speaking, there is a problem with a module that is NOT the engine control module, so it will not affect how the car starts or runs-but you may develop a problem with your ABS, or your remote keyless entry-or any other module that controls a subsystem. It can be caused by something as simple as a bad connection in a harness or connector. If it were me, I'd disconnect the battery at the negative post, leave it off for 5 minutes, hook it back up and start the car and let it IDLE for 5 minutes-then drive it gently for another 10, allowing the sensors to reset the engine computer and the engine computer to get used to 'new' feedback. This might cure it-worth a try, anyway. If you can get someone with a good scanner that does live data, chances are it will also do manufacturer' specific codes (P1613 is a Hyundai specific code) it might pick up additional codes related to what module is unhappy.

P1613 trouble code. When you start the engine, the TCM (transmission control module) sends a test signal along the wire to the ECM (engine control module) it uses to request the check engine lamp. P1613 indicates that the test signal voltage is more than 120% of battery voltage.

I'd recommend clearing the code to see if it comes back. It's possible this was a one-time error. If it does come back, it'll be very difficult to diagnose. The problems could be:
1. Improper signal from TCM (defective TCM)
2. Improper signal measurement in ECM (defective ECM)
3. Irregular feedback from an actuator that causes bleed-over into this signal circuit in either the ECM or TCM.

The last case of this I recall was a defective TCM
