1.Check the idle speed, and adjust it it necessary (see
section 'l '1 ).
Pull out the service check connector 2P (BRN and BLK
wires) from the connector holder located under the
dash on the front passenger side, then connect the
SCS service connector (T/N 07PAZ - 0010'100) to it.
Start the engine. Hold the engine at 3.000 rpm with
no load {A,/T in E or E. M/T in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. 1 ignition wire,
then point the light toward the pointer on the timing
