Engine Screen Information A) Purpose It has been made possible to copy the engine information (Q adjustment, QR code, engine serial number) stored in the ECM to the new ECM when the ECM and injector are replaced. B) How to go to this screen See the service support screen operation. C) Engine start restriction When this screen is displayed, the engine cannot be started. D) Screen The engine information held in computer A can be checked as follows. The information inside the ECM is checked by changing the display mode with the method shown in "Replacing computer A at the Same Time". 1. Pages 1 to 4: Injector cylinder 1 to 4 QR code (Pages 5 and 6 are not used and cannot be input). 2. Page 7: Q resistance data 3. Page 8: Engine serial (number) 4. ECM Part Number E) Monitor operation method 1) View Mode. 2) Edit Mode Can only be shifted to during QR code display. F) Engine Information (Q resistance, QR code, engine serial number) Copying Method If the ECM is replaced with a new one for any reason, the engine information is copied with the procedure below 1. Connect the service ECM and check the following. . The old ECM information must still be in computer A. . The ECM must match the model (Check on the ECM parts nimber screen). . No display for faulty computer A EEPROM or faulty EEPROM on ECM. 2. Go to the engine information screen, then hold down for 3 seconds. The buzzer buzzes and the copy starts. . The display may be any page (1 to 8) and either display mode (computer A or ECM). During copying, the display is as below. During writing, the error code 99 is displayed. Wait about 10 seconds. When the copy ends normally, the error code 00 is displayed. When the copy ends abnormally, error code displayed. . Example: Starting copying from the Q resistance screen. 00: Normal. 01: Message interruption. 02: Message internal trouble. 03: Outside instruction value constant. 04: Engine running. 98: Faulty EEPROM 99: Writing 3. When the copy ends normally, check that the information has been rewritten by switching the key switch OFF => ON once. G) Rewriting Injector QR Codes When an injector is replaced, input and write the QR codes with the following procedure. 1. Arrange for the replacement injector. Input the part below from the character array written on the injector QR Code Input the QR codes one at a time. Engine information screen Pages 1 to 4 (4 cylinders engine) or Pages 1 to 6 (6 cylinders engine) correspond to the injectors with those numbers (See the figure below.) 2. Hold down the idle switch for 1 second to shift the Edit mode. 3. Cursor is displayed. 4. Move the cursor with the washer and light switchs. Use the wiper and the auto idle switchs to raise and lower the value and input the QR codes written on the injector. 5. When the QR code input is complete, press . The buzzer buzzes once and the writing starts. The error code 99 (writing) is displayed. When the copy ends normally, the error code 00 is displayed. When the writing ends abnormally, the buzzer buzzes twice and the error code is displayed. (To cancel input, press the horn switch) 6. Switch OFF the key switch, then ON again and check that the QR codes have been written. H) When Replacing Computer A at the Same Time If the ECM and computer A have trouble at the same time and the engine information inside the ECM cannot be used, restore the engine information with the procedure below. 1. Rather than a service ECM, arrange for an ECM with the engine information already written into it and use that as the replacement. . An ECM with the engine information already written into it means one into which the Q resistance data has been written with EMPS. 2. Input the injector QR codes one at a time (with the procedure in the preceding item). I) Engine Information Obtained Timing The engine information is acquired only the first time the key is switched ON after assembly. J) Redoing Engine Information Obtained To re-aquire the engine information, on the engine information screen, hold down the washer switch and the light switch for 10 seconds. K) Trouble Display If the engine information cannot be displayed correctly due to an ECM time-out, CAN communications trouble, or faulty EEPROM, the display is all Fs. .
