Is there a way to test a computer on a jeep g cherokee laredo that is not showing codes in the onboard test system? Its a 5.2
Looking at your past questions it's a 1994 if we are talking about the same Jeep, it does not have OBDII that was made standard in 1996. It should have a DTC system that uses CEL flash patterns
