Code P1000: OBD System Readiness Test Not Complete

Diagnostic & Technical Explanation
Code P1000 (OBD System Readiness Test Not Complete) is a status indicator, not a fault: the powertrain module sets it after battery disconnection or code clearing until every OBD readiness monitor has completed its drive-cycle self-test. It clears itself once the drive cycle finishes; it stores no failure and triggers no repair by itself, but the vehicle will fail an emissions inspection while monitors remain incomplete.

Probability-Ranked Repair Procedures (3 Ranked Fixes)

Rank #1

Complete the manufacturer drive cycle

Easy DIY
Parts Estimate: $1.0–$5.0 USD Labor Estimate: 1.5 Shop Hours
  1. 1. Confirm no other DTCs are stored - address any real faults first
  2. 2. Drive the manufacturer's specified drive cycle (typically a cold start, mixed city and 55 mph steady-state segments)
  3. 3. Re-scan and confirm all readiness monitors report Complete
Required Replacement Parts: 🔧 OBD-II scan tool
Rank #2

Verify battery and charging health before the drive cycle

Easy DIY
Parts Estimate: $5.0–$25.0 USD Labor Estimate: 0.3 Shop Hours
  1. 1. Test battery resting voltage (12.4V+) and charging voltage (13.5-14.7V)
  2. 2. A weak battery resets monitors and prevents completion
  3. 3. Recharge or replace the battery before repeating the drive cycle
Required Replacement Parts: 🔧 Automotive battery tester
Rank #3

Diagnose a monitor that never completes

Professional Required
Parts Estimate: $10.0–$60.0 USD Labor Estimate: 1.0 Shop Hours
  1. 1. Identify which monitor stays incomplete on a capable scan tool
  2. 2. Check the enabling criteria for that monitor (fuel level, ambient temperature, trip requirements)
  3. 3. Pinpoint-test the sensors that gate the monitor per service information
Required Replacement Parts: 🔧 Professional bi-directional scan tool
