Anti-Theft - Passive Anti-Theft System (PATS)
PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESETSpecial Tool(s)
Special Tool(s):
NOTE:
- If the instrument cluster (IC) or the PCM is being replaced (or both), the parameters must be reset in both modules or the vehicle will experience a passive anti-theft system (PATS) no-start. This will occur even if the vehicle is not equipped with PATS. PATS vehicles and non-PATS vehicles have parameters in the IC and the PCM and they must be reset whenever either (or both) module(s) is (are) replaced.
- When using the IDS, the IC and the PCM parameters are reset at the same time.
- Once security access has been granted, multiple security access commands should be executed (if necessary) prior to exiting the command menu. This avoids an additional security access procedure and the associated 10 minute time delay.
1. NOTE: If the IC was replaced, follow Steps 1-10. If the IC and the PCM were replaced, follow Steps 1-10. If only the PCM was replaced, follow steps 1-3, then go to Step 10.
