| + | - The vehicle speed must be zero. | ||
| + | - ThrotPos must exceed 72%. (Verify by logging.) | ||
| + | - Beginning with the ignition on but the engine not running, the minimum sequence is: turn the key off (first time) for 1/2 second, on for 1/2 second, off (second time) for 1/2 second, on for 1/2 second, off (third time) for 1/2 second, then on and leave on. (The speed of the off-on should be about like a clock going tick-tock or a bit faster. Failure to reset usually is caused by toggling the key too slowly.) | ||
| + | - If you initiate logging prior to performing the reset sequence, the logging will halt (the seconds counter will stop updating) the instant the reset happens. | ||
| + | - With firmware v3.18.205 or earlier in the ECU, to be sure that the default settings are properly saved after executing the hard-boot procedure, use the PC app to modify any configuration value and Save to ECU before shutting off the ignition. | ||
