Self Test/Continuous Memory and Clear DTCs

During vehicle operation, the RCM will detect and store both intermittent (continuous memory) and hard failure DTCs in non-volatile memory.

The DTC strategy employed by the RCM incorporates a time-out scheme for determining when a concern exists in the system. This requires a concern to mature for up to one minute in the system before the RCM will store a DTC. For the RCM to determine that a concern no longer exists, the concern must be absent for up to one minute. The actual detection time-outs vary with each DTC.

Once 127 ignition cycles have been recorded by the RCM since the concern was last detected, all CMDTCs will automatically be removed from memory.
