my guess, NO SCAN TOOL?
you can't fix car with out, a (drum roll) SCAN TOOL
the modern car also cuts cruise for many reasons.
(death) reason and #2, billion dollar class action suits. (read news?)
so they now cut the cruise for lots of engine failures and trans.
no scanning the PCM now, you lose.
2004 RAV 4 no engine stated.
if it has TBW (throttle by wire ) that too, cuts CRUISE big time if iffy
yes,DTCs for TBW or limphome of any kind !!!
what engine, we cant fix engine issues, with out that.
only about 10% here post that. so most answer are wrong.
imagine with body shells missing , see that < what is it,its a drive train. what is yours? engine and trans. what?
Check engine light on runnning
Scan tool shows, DTC errors. BINGO.
scan tool show stuck on limphome?
Throttle or idle errors of any kind?
there is no cruise module on ours USA>
The PCM mimics that in pure software (fact)
so if the PCM is unhappy, it does in fact cut cruise.
no scan tool makes all this IMPOSSIBLE on all newer cars !!!!
see PCM see throttle motor, bingo its cruise TOO.
