Without Using MUT-II Tester Or Scan Tool
CAUTION:
Inspection should be completed within 20 seconds after accelerator pedal was depressed. If it takes longer than 20 seconds, TCL system function will stop and engine speed will gradually increase.
NOTE:
Because the TCL OFF indicator will flash when TCL system operation is stopped, diagnosis codes should be erased if you notice that indicator light is flashing.
Turn TCL switch to on. Place front wheels onto a speedometer tester or a chassis dynamo and start the engine. The front wheels may also be jacked up if speedometer tester or chassis dynamo is not available. Move shift lever to "D" drive position. Engine speed should be restrained and not allowed to increase as it would normally in park position.
