Yortt Posted December 2, 2018 Posted December 2, 2018 I have just corrupted the PCM in a 2012 XR6T trying to write to it (email sent to Roland). Has anyone else had the problem and if so how did you fix it ? Quote
Roland@pcmtec Posted December 2, 2018 Posted December 2, 2018 Just use recovery mode (checkbox) and write back the original file. The PCMs are impossible to brick from our testing. Quote
Stevew Posted December 9, 2018 Posted December 9, 2018 What does recovery mode do different compared to writing the file to the PCM without the check box marked? Quote
Roland@pcmtec Posted December 9, 2018 Posted December 9, 2018 It ignores all errors. When a flash has failed the detect method will read all nulls and fail to determine what the vehicle is. The PCM will also be stuck in the bootloader so all normal read PID commands will also fail. By selecting recovery mode and selecting the pcm type manually it will ignore all errors and force the tec file in. Even if you select the wrong flash type it will let you continue so it is not recommended unless you have a failed flash write or have flashed an incompatible os. Quote
Stevew Posted December 9, 2018 Posted December 9, 2018 Thanks for the info. I had a laptop die on me halfway through a flash last night, got it going again and re-flashed successfully and the car fired up no worries. This morning the car would crank but would not fire. Do you think something could have been corrupted still even though it flashed successfully and worth doing the recovery mode option? Quote
Roland@pcmtec Posted December 9, 2018 Posted December 9, 2018 If it cranks the flash succeded. It won't crank unless the calibration is running. A normal flash will achieve the same as a recovery flash. Recovery just let's you flash when it won't detect. Quote
