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
oN.
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
the fuse so vou can reset them.the customer's code number and make note ot the radio

'13. Measure the clearance between the clutch end plate
and top disc with a dial indicator. Zero the dial indi-
cator with the clutch end plate lowered and lift it up
to the snap ring. The distance that the clutch end
plate moves is the clearance between the clutch end
plate and top disc.
NOTEr Measure at three locations.
Clutch End Plate-to-Too Disc Clearance:
1 4. lf the clearance is not within the service limits, select
a new clutch end plate lrom the following table.
NOTE: It the thickest clutch end plate is installed,
but the clearance is still over the standard, replace
the clutch discs and clutch Dlates.

Follow lhe chargor manutacturer's instluctions and chargo tho battory at a prop61 rate.
NOTE: The original radio has a coded theft protection circuit. lt service to the car requires any of the lollowing, be sure
to get the customer's code number before- disconnecting the battery.- removing No. 32 (7.5 Al fuse from the under-hood fuse/relay box- removing the radio,
After service, reconnect power to the radio and turn it on. When the word "CODE" is displayed, enter the customer's
s-digir code to restore radio operation,
Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. It you don'r have one of these com-puterized testers, follow this conventional test procedure:
To get accurate results, the temperature ot the electrolyte must be between TOoF l21ool and IOOoF {38oCl.
lf the case is cracked or the posts are loose,
replace the battery.
lf the indicator shows low electrolvte, add
distilled water it oossible.
