1. Enter Self-Diagnostic Mode

WARNING: This page is about a different car, the 2004 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition switch ON.
  2. Enter self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned ON), press OFF switch for at least 5 seconds.
CAUTION:
  • If battery voltage drops below 12V during diagnosis STEP 3, actuator speed becomes slower and as a result, the system may generate an error even when operation is usual. To avoid this, start engine before performing this diagnosis.
  • Former STEP 1 (LEDs and display screen are checked) no longer exist in this self-diagnosis function.
  1. GO TO 2.
