Memorized vs. Non-Memorized Codes
WARNING: This page is about a different variant/trim than selected.
Some sensor or circuit failures are stored in ECU and are known as memorized codes. While other circuit failures, called non-memorized codes, are not stored. Non-memorized codes can be retrieved if ignition is not turned off before accessing codes.
NOTE:
To access non-memorized trouble codes, DO NOT stop engine. Connect jumper wire across self-diagnostic connector terminals TEN and GND. Observe MIL and note trouble codes.
