Test Mode 2: Notes

  1. 11. Remove the MPCS service connector from the driver's under-dash fuse/relay, box multiplex control inspection connector socket for 5-10 seconds, then re-insert it to enter Mode 2. When the system enters Mode 2, the front and rear map lights will flash two times quickly and then go off.
    NOTE: If the MPCS connector is disconnected for too short or too long of a time, or the ignition switch is turned to LOCK (0), the system will return to Test Mode 1.
  2. 12. The following tables list the circuits that can be checked in Test Mode 2. Operate the switch that is most closely related to the problem. If the circuit is OK, the map lights will blink once. If the circuit is faulty, there will be no indication.
