⁽¹⁾	DTC Condition & Circuit Test/Step

⁽²⁾	Diagnose DTC U1041, SCP invalid or missing vehicle speed message or DTC U1051, SCP invalid or missing data for brakes. See appropriate ANTI-LOCK BRAKE article in the ACCESSORIES & ELECTRICAL section for test procedures.

⁽³⁾	See appropritate ELECTRONIC CONTROLS article in AUTMOMATIC TRANSMISSIONS section.

⁽⁴⁾	DTC P1000 is ignored in KOEO ON-DEMAND SELF-TEST and KOER ON-DEMAND SELF-TEST. Disregard DTC P1000 and continue as directed.

⁽⁵⁾	Diagnose DTC U1020, SCP invalid or missing data for A/C clutch. See appropriate article in the AIR CONDITIONING & HEAT section for test procedures.

⁽⁶⁾	Diagnose DTC U1135, SCP invalid or missing data from ignition switch/starter steering column ignition lighting control module. See appropriate STEERING COLUMN article in the ACCESSORIES & ELECTRICAL section for test procedures.

⁽⁷⁾	Diagnose DTC U1451, SCP invalid or missing data from anti-theft module. See appropriate ANTI-THEFT article in the ACCESSORIES & ELECTRICAL section for test procedures.

⁽⁸⁾	Diagnose DTC U1850, SCP invalid or missing data from fuel system. See appropriate article in WIRING DIAGRAMS section.

⁽⁹⁾	For "U" DTCs received during self-test of another module, go to MULTIPLEX COMMUNICATION NETWORK CONCERN under SYMPTOMS in TESTS W/O CODES - EEC-V article.
