The procedure is as follows:

turn on key wait 3 seconds (critical time)

tap pedal 5 times (in about 5 seconds)

lift off pedal wait 7 seconds (critical)

hold down for approx 10 seconds until code and hour meter alternate (note: if you start the engine at this time it will go into O2 sensor test and not clear the code)

This procedure works much better when engine is warm. A helpful hint is to either count strobe flashes or use a stopwatch. It is kind of hard to use display flashes as counter.
