lgnition Timing Inspection and Setting
1.Start the engine. Hold the engine at 3,00O rpm with
no load (A/T in S or E position, M/T in neutral) until
the radiator fan comes on, then let it idle.
Pull out the service check connector located behind
the right kick panel. Connect the BRN/WHT and BLK
terminals with the SCS short connector.
4. Adiust ignition timing, if necessary, to the follow-
ing specifications:
lgnition Timing:
16 t 2 BTDC (RED) at 75O 1 50 rpm in noutral
NOTE:
a Shift lever must be in neutral.
a All electrical systems should be turned OFF.DATA LINKCONNECTOR {3-P}NOTE: Do not attachthe jumper wire.

Troubleshooting
NOTE:
a The numbers in the table show the troubleshooting sequence.
a Before troubleshooting,- check the No.15 {10 A) and *No. 24 fuses in the under-dash fuse/relay box, and the No.41 (1OO A), No.39(50 A). and No.42 (20 Al fuses in the under-hood fuse/relav box.- check that the horn sounds.
check the tachometer to see if it wo.ks pfoperly.
*No. 24 {15 A): Bl8B1 engine
No. 24 {2O A}: 818C1 engine
