Default Re: RCM or CPS problem
The student reference and the service manual both call it a pulse module. But I've only seen one PM fail in the nine years I've been in the group.


Also, there are two pulse modules:
  • One for Automatics that enables "turn to start" for autocranking.
  • One for Manuals that enables no "turn to start" for autocranking.
Both models arbitrate the signals from the key and ECM to cut out the starter at 400 rpm (when the engine starts).
