How To Perform Test
The procedure for performing the PLAUSIBILITY SWITCH test is described below and summarized in the above illustration. See Fig 1 .
- Ignition must be on when performing this and all other tests with the J 36210 tester.
- Install the J 36210 tester and J 36210-90 adapter; turn ignition ON. The READY LED must be ON.
- Select SWITCH PLAUS. test mode on the test selector buttons.
- SLOWLY depress the brake pedal and watch the row of LEDs at the bottom of tester. Observe the sequence in which they turn on. The normal sequence is described below:
- As the pedal is applied, the BLS LED will turn on at approximately the same time as the S2A LED. These LEDs should remain on as the test is continued.
- As the brake pedal is pressed further downward, the S2B LED should turn on and remain on as the test continues.
- As the pedal is applied further and approaches full stroke, the S2B LED should turn on.
- Release the pedal and evaluate the observed sequence. Repeat the pedal application as many times as necessary to confirm the sequence.
