It the self-diagnosis LQ4 indicator light does not blink, perform an inspection according to the table below.
a lf a customer describes the symptoms for codes 3, (yet the LQ! indicator light is not blinkingl, 6, 1 1 or 15, it will
be necessa.y to recreate the symptom by test driving. and then checking the @ indicator light with the ignition still

e lt ttre @ indicator light displays codes olher than those listed above or stays lit continuously, the TCM is faulty.. Sometimes the Lqd indicator light and the Malfunction Indicator Lamp (MlL)/Check Engine light may come on simul-taneously. lf so, check the PGM-Fl system according to the numbe. of blinks on the MIL/Check Engine light. thenreset the memory by removing the BACK UP fuse in the unde.-hood fuse/relay box for more than 1O seconds. Drive
the vehicle for several minutes at speed over 30 mph (5O km/h), then recheck the MIL/Check Engine light.
NOTE:
. PGM-FI system
The PGM-Fl system on this model is a sequential multiport fuel injection system.a Disconnecting the BACK UP luse also cancels the radio anti-theft code. preset stations and the clock setting. Get
