MICS (Driver's and Passenger's MICU) Self-diagnostic Function
Test Mode 2
  1. While in Test Mode 1, turn off the MPCS short connector switch (A) for about 5 to 10 seconds, then turn it on again.
  1. The ceiling light and ignition key light should come on for 2 seconds, go out, then blinks twice more at 0.2 second intervals. This means the system has gone from Test Mode 1 to Test Mode 2.
  1. While still in Test Mode 2, operate the switches in the table shown. If the circuit is OK, the ceiling light and ignition key light blink once. If the circuit is faulty, the ceiling light and ignition key light do not blink.
    • If the ceiling light and ignition key light do not blink even a switch is operated, check two or three other circuits listed in the table. If the ceiling light blinks for each circuit, the additional circuits are OK, repair the short or open circuit that failed the test in Step 3 .
    • If the ceiling light and ignition key light do not blink again, this multiple failed circuits mean that the control unit has failed without triggering a DTC. Test a few more circuits. If they also fail, test the related control units input test.
