Collision repair in Nigeria is monkey business. Got pictures to back up my claim. I think we need to introduce collision repair classes to our curriculum and let the public know what signs to look out for when buying vehicles that have been involved in accidents. Specimen vehicle is a Lexusus ES330 that kills batteries overnight. Research indicates the vehicle has been involved in two frontal impact accidents. Repair is more than just cosmetics, repair also has to be electrical and computerized. |

Collision repair without connecting airbag sensors to vehicle frame and air bag light blinking on the dashboard is that a proper repair? |

The issue of consulting factory documentation before making repairs is contentious. Here is Toyota's expressly stated position: Verify open recalls on vehicles prior to performing repairs. Confirm applicable open Special Service Campaigns (SSCs) or Safety Recalls (SRs) Confirm also if it is a salvage vehicle. Deny New Vehicle Limited Warranty coverage for Salvage titles. Doing all the above requires access to factory documentation. For a repair to meet with the standards set by the vehicle manufacturer, it has to begin and if care is not taken, end with factory documentation. That is how it is done in the West. |

Wikipedia is not the most authoritative source but who cares, we are not writing a scholarly paper for submission to a peer-reviewed journal For our purposes, it will do just fine Workshop pictures (main course) on the way...these are just what they are appetizers

Previous repair work had made the OBD II port inaccessible so we had to do some invasive surgery to get at it. Why repair a vehicle and tuck away the OBD II port so it cannot be reached normally?

Blatant copy and paste with modifications of the words of Protech, a member of ToyotaNation:
This is in respect of the DTC U0100 code. DTC Name: Lost Communication with ECM/PCM "A" DTC Description: The transmission control ECU and ECM communicate with each other via the CAN communication line. DTC Detection condition: No communication with the ECM (1 trip detection logic) DTC Symptoms: 1. Gear does not change 2. It is only possible to drive 1st and reverse gears after vehicle stops If you are a CAN system newbie, this video should help: https://www.youtube.com/watch?v=FqLDpHsxvf8 Previous posts that deal with OBD II, trips and trip detection logic http://nairaland.com/search?q="one+trip+detection+logic"&board=78 applies the definition to live vehicle problems https://www.nairaland.com/3661728/on-board-diagnostics-obd-ii-questions/3#54620232 Defines the term trip in OBD II terms The client was told to either replace his transmission or allow then to install a transmission for another vehicle in his vehicle, can't recall the name of the particular model of Toyota A study of the factory documentation does not indicate that the problem lies with the transmission, it instead suggests that the following trouble areas be analyzed: Five possible reasons and areas to check: 1. that one of the wires is cut and so signals cannot travel between both 2. that any two of the wires has been bridged and so the signals have become confused 3.that we have a bad Engine brainbox (ECM) in technical speak 4. that we have a bad Transmission control ECU (T-ECU) 5. That there is a fault within the CAN communication system components Summary:The transmission control ECU and ECM communicate with each other via the CAN communication line BUT THAT that communication has been interrupted. So it will next be necessary to disconnect the Engine ECU and the transmission control ECU connectors and then check the resistance of the wiring. If that is where the problem is..then the wires and or the wiring harness will need to be repaired If it is not, then ...it will mean the problem is with the transmission control ECU which will have to be replaced If that still does not solve the problem, the final procedure is to replace the Engine ECU |

P3001 code on a Sienna? |
Re: Dealership Level Diagnostics - Toyota (1996 - 2018)- Electrical N Mechanical by AutoElectNG: 8:25am On Oct 03, 2020 |
If you have a Toyota Sienna 2004 - 2010, take the sensible precaution to replace the stock radiator around 140,000 miles (whether or not you have an issue) or risk losing the transmission which is a vastly more expensive fix in time, labour and money. This is due to corrosion resulting in the comingling of coolant and transmission fluid, transmission contamination and failure. Toyota isn't perfect after all, all brands have issues, just that some might have more issues than others. 4 Likes 3 Shares |
