The 91 XJ went to the MOPAR computer, best I recall. That had a real,
honest to goodness check engine light with stored codes. The old
Renix was just capable of running the engine and fuel system - no
stored codes (or codes off any type, for that matter). The "Check"
light was simply a timer that set the light at 80,000 miles, period.
You were supposed to replace the cat and/or the O2 sensor then.
Useless bit of EPA compliance, nothing more.
