Continuity Test

1. Disconnect the multiple connector from the ignition switch.
2. Test the switch continuity in the following illustration. Connect a self-powered test lamp or ohmmeter between the blade terminals indicated on the chart in the illustration. No continuity between any blade and the ground terminal should exist in any switch position except the proof and ground pins (P1, P2 and GND) in the START position only.
3. For an engine won't crank condition, determine if the condition exists with the gearshift lever in both the PARK and NEUTRAL positions before performing the ignition switch continuity test. If the no-crank condition occurs with gearshift lever in one shift lever position but not the other, a more probable cause is the transmission range (TR) sensor located on the transmission. See Transmission and Drivetrain for diagnosis and testing.
4. With the ignition switch in OFF or LOCK there is no continuity between the battery terminals and any other terminals.
5. There is continuity between P1 and P2.
6. With ignition switch in RUN, there is continuity between:
B4 and A4
B1 and A1
B5 and 11
B2 and A2
B3 and A3
7. With ignition switch in START, there is continuity between:
B4 and STA
B1 and 12
B5 and 11
GND and P1
GND and P2
8. With ignition switch in ACC, there is continuity between B5 and A1.
