TABLE A-1
STEP
1 Did you perform ENGINE DIAGNOSIS FLOW
TABLE in SECTION 6?
2 Test switch terminal circuit check:
1) Check for continuity from "B1" terminal of ECM/
PCM connector to ground.
Is there continuity?
3 MIL bulb and circuit check:
1) Turn ignition switch to ON position, leaving en-
gine OFF.
2) Measure voltage from "C7" terminal of ECM/
PCM connector to ground.
Is voltage within 10 – 14V?
