Cleared stored trouble codes, some for ABS, SRS, and the manufacturer enhanced. No check engine or other light was present, and to the best of my capability I went through everything to make sure problems didn't exist. Maybe the codes weren't cleared for various reasons, but being I'm the 'new' owner I wanted a reset. Actually started this yesterday, but without results it was not worth mentioning.
Under the enhanced codes, 16 Toyota Readiness codes set. Drove some and this morning there were only 8 Readiness codes. Today I let warm till operational temperature and drove some city and highway (10 minutes no cruise control). Now there's only 5 Readiness codes showing, P0300, P0100, P0102, P0103, and P0125.
Here's what the 16 codes first looked like:
P0300- Toyota Readiness Random Misfire Detected
P0011- Toyota Readiness Intake Camshaft Position Timing - Over - Advanced (Bank 1)
P0012- Toyota Readiness Intake Camshaft Position Timing - Over - Retarded (Bank 1)
P0021- Toyota Readiness Intake Camshaft Position Timing - Over - Advanced (Bank 2)
P0022- Toyota Readiness Intake Camshaft Position Timing - Over - Retarded (Bank 2)
P0100- Toyota Readiness Mass or Volume Air Flow Circuit
P0102- Toyota Readiness Mass or Volume Air Flow Circuit Low Input
P0103- Toyota Readiness Mass or Volume Air Flow Circuit High Input
P0125- Toyota Readiness Insufficient Coolant Temp For Closed Loop Fuel Control
P0420- Toyota Readiness Catalyst System Efficiency Below Threshold (Bank 1)
P0430- Toyota Readiness Catalyst System Efficiency Below Threshold (Bank 2)
P0500- Toyota Readiness Vehicle Speed Sensor A
P0705- Toyota Readiness Transmission Range Sensor Circuit (PRNDL Input)
P0717- Toyota Readiness Turbine/Input Shaft Speed Sensor Circuit No Signal
P0722- Toyota Readiness Output Shaft Speed Sensor Circuit No Signal
P0748- Toyota Readiness Pressure Control Solenoid A Electrical

For ABS codes the instructions I read were to clear the codes and see what comes back, nothing so far. That's what inspired me to clear them all.
