lovejones Posted October 30, 2015 Report Share Posted October 30, 2015 ok ill keep this a brief as i can whilst out traveling the engine light came on. thought nothing of it tbh as it used to flicker on ruff terrain. anyway, around that time i started to lose power, id be driving say 100kph and then it would slow down to about 80kph, it felt like the turbo wasn't working, i rev two or 3 times and then would kick back in. i thought that maybe the i/c had cracked or similar (it does have some oil around two corners, and i noticed some oil leakage down the left side. not much) i took the i/c off gave it a clean and then see how it went, it run fine for a fair few k's then the same issue, this was a reoccurring event. i then disconnected the battery to see if this would clear the engine light, it did, and for about 300k was fine, then when i hit some corrugated road it came on. i did the same, was fine again, until i did a u turn. so as you can guess, there is no factor that is the same for the engine light to come on, nor distance, i have driven a couple ks and it comes on, i have also driven 500ks before it came on and id lose power. the turbo played up a bit then was fine for a week or so, and was until the car decided to lose all the instrument panel ( rev counter, speed counter, fuel gauge, sub tank gauge etc) then the air bag light came on flashing and the sub tank light as well as the engine light. it got me home whilst i held the secondary battery button in. so battery dead, check the nator, it appears its given up. no issue, ill get another. so, i have just replaced the nator and checked and its running at 14.63, so that solved that issue. however, i still have that bloody engine light on. i am wondering, do i need to clear the memory, if the engine light came on due to the nator giving up (though doesn't explain power loss), now the new one is in, would the engine light go out or does it need to be cleared? cheers for your help. the car is the gu grenade 230000ks Link to comment Share on other sites More sharing options...
Rumcajs Posted October 31, 2015 Report Share Posted October 31, 2015 (edited) G'day, you'll need to read the codes first. Then you can reset them if it is nothing serious. Fault Codes The 4 digit Fault Codes are displayed in two parts as flashes of the Check Engine Lamp. The first part represents the first two digits of the fault code. These are displayed as 0.6 second flashes. The second part displays the second two digits of the fault code. These are displayed as 0.3 second flashes. There is a 0.9 second pause between the first and second parts of the code. There is a 2.1 second gap between separate codes of different value. Multiple codes will flash in order of numerical value, from lowest to highest. Fault Code Erasure Fault Code Erasure can be carried out with a Compatible Scan Tool or manually. Manual Erasure: 1. Carry out Fault Code Extraction. 2. While the Fault Codes are being displayed, bridge Diagnostic Connector terminals 1 and 8. 3. Wait at least two seconds. 4. Disconnect the bridge between Diagnostic Connector terminals 1 and 8. (This will erase the Fault Codes from ECM memory) Should the above procedure fail to erase the Fault Codes; Disconnect the battery negative cable or remove power to the ECM for 24 hours. Ensure that other memory codes are known prior to performing this procedure. Fault Code Extraction Fault Code Extraction can be carried out with a Compatible Scan Tool or manually. Manual Extraction: 1. Switch ignition ON. 2. Confirm the Check Engine Lamp illuminates. (The system will be in Diagnostic Test Mode I.) 3. Bridge Diagnostic Connector terminals 1 and 8. Confirm the Check Engine Lamp extinguishes. 4. Wait at least two seconds. 5. Disconnect the bridge between Diagnostic Connector terminals 1 and 8. (The system will be in Diagnostic Test Mode II.) 6. Read Fault Codes as flashes of the Check Engine Lamp. Do not switch ignition off during this procedure or the system returns to Diagnostic Test Mode I. Fault Code Table Code # Circuit and Status 0102 Mass Air Flow Sensor Circuit, Sensor or ECM failure 0103 Engine Coolant Temperature Sensor (excessively high or low voltage at ECM) Circuit, Sensor or ECM failure 0104 Vehicle Speed Sensor (signal not sent when vehicle is in motion) Circuit, Sensor or ECM failure 0203 Accelerator Position Switch (incorrect signal sent to ECM) Accelerator Position Switch fault or ECM failure 0208 Overheating Fault Cooling Fan system failure, Engine coolant re-filling procedure not followed, Cooling system faulty, Engine lubrication problem 0301 ECM 2, failure (calculation function is malfunctioning) Internal IC failure 0402 Fuel Temperature Sensor (incorrect signal for fuel temperature received) Refer to Injection Pump Control Unit Circuit, Sensor or ECM failure 0403 Accelerator Position Sensor (out of range signal received from sensor or switch assembly) Circuit malfunction, Accelerator Position Sensor failure, Accelerator Pedal Dual Contact Position Switch failure, ECM failure 0406 INT/AIR volume (excessively high signal from Mass Air Flow Sensor) Air Duct, Charge Air cooler, Variable Nozzle Turbo Charger Control System, Variable Nozzle Turbo Charger, Mass Air Flow Sensor failure, Circuit malfunction 0407 Crankshaft Position Sensor Circuit, Sensor or ECM failure 0502 Battery voltage (excessively high voltage sent to battery) Incorrect jump starting, Battery, Alternator, ECM 0504 Automatic Transmission Communication Line (ECM receives incorrect voltage from Transmission ECM) Circuit malfunction, Automatic Transmission ECM 0505 No faults detected Monitored circuits are operating normally 0701 Camshaft Position Sensor (incorrect signal from the Injection Pump Control Unit) Refer to Injection Pump Control Unit Circuit malfunction, Injection Pump Control Unit 0702 Top Dead Centre Pulse Signal (incorrect signal from the Injection Pump Control Unit) Refer to Injection Pump Control Unit Circuit malfunction, Injection Pump Control Unit 0703 Pump Communication Line (incorrect signal from the Injection Pump Control Unit) Refer to Injection Pump Control Unit Circuit malfunction, Injection Pump Control Unit 0704 Spill Valve Circuit Circuit malfunction, Injection Pump Control Unit 0705 Pump Control Module Circuit malfunction, Injection Pump Control Unit failure 0706 Spill Valve Circuit malfunction, Spill Valve, Injection Pump Control Unit 0707 Fuel Injection Timing Control System Circuit malfunction, Injection Pump Control Unit failure, Poor fuel quality 0802 Barometric Pressure Sensor (built into the ECM) Internal circuit malfunction, ECM failure 0804 ECM internal input signal processing function malfunctioning ECM failure 0807 Brake Light Switch Circuit malfunction, Switch failure 0901 ECM Failure (calculation function is malfunctioning) Internal IC failure 0902 ECM Relay (incorrect voltage received by the ECM from the relay) Main Relay malfunction, Circuit malfunction 0903 ECM Internal input signal processing function malfunctioning ECM failure 0905 Turbo Pressure Circuit malfunction, Charge Air Pressure Sensor failure 1003 EGR Volume Control Valve Circuit malfunction, EGR Volume Control Valve failure 1004 Fuel Cut System Circuit malfunction, Injection Pump Control Unit failure, ECM failure 1401 to 1408 Nissan Anti Theft System Diagnostic link connector, the white connector just to the left and down from bonnet release lever. Above info may apply to your model and diagnostic connector may look like the one in the photo which is OBD type but yours could have grey Consult type Or alternatively you could purchase appropriate ECUTalk cable and use software supplied with on your notebook/laptop to do it easy way. I thoroughly recommend you to go this route as the ECUTalk is invaluable tool. I'm guessing from you avatar pic that yours is non CrD model (On CrD or common rail diesel all this info doesn't apply.) ECUTalk cables interface Cheers Edited October 31, 2015 by Rumcajs lovejones 1 Link to comment Share on other sites More sharing options...
