Diagnosis

The self-test of the ECU is done once atinitialization after key "ON" is detected andcheck-sum is recognised. There are 16condition bits in ECU to determine the actualfault on ECU.

(MIL) Control Circuit P0650

The purpose is to diagnose electrical errorsbythehardware for the MIL. The signals arecontrolled bytheLowsidedriver ATIC39. Thedriver ATIC39 can distinguish between threeerrors: Short to battery (SCB), Short toground (SCG)and Open load (OL). SCB andreal OL are detected bythe driver only if theoutput is driven (ON-state), additionally SCGwill be detected as OL in ON-state.If the output is non-driven (OFF-state) by thedriver, SCG is detected only.
