Does the ignition key light blink and the beeper beep for each additional circuit?
YES - The additional circuits are OK. Repair the short or open in the circuit that failed the test in the proceeding step. Refer to the test(s) for that
individual system.
NO - Multiple failed circuits can mean that the control unit has failed, but without triggering a DTC. Test a few more circuits. If they also fail,
substitute a known-good control unit, then recheck. If the system works properly, the original control unit is faulty; replace it. If there is still a
malfunction, substitute a known-good control unit for the next most likely faulty control unit, then recheck. If the system works properly, that
control unit is faulty; replace it.
