TROUBLE DIAGNOSIS — BASIC INSPECTION
3. Cruise test
lBefore road test, familiarize yourself with all test procedures and
items to check.
lConduct tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.
Refer to the following items.
1. CHECK BEFORE ENGINE IS STARTED
1.CHECK O/D OFF INDICATOR LAMP
1. Park vehicle on flat surface.
2. Turn ignition switch to “OFF” position.
3. Move selector lever to “P” position.
4. Set overdrive control switch to "ON" position.
5. Turn ignition switch to “ON” position. (Do not start engine.)
6. Does O/D OFF indicator lamp come on for about 2 seconds?
Ye s o r N o
Yes >>GOTO2
No >> Stop ROAD TEST. Go to “1. O/D OFF Indicator Lamp
Does Not Come On”,AT - 2 3 2 , "
