4. The stoplight switch is operating properly if there is continuity between
terminals 3 and 4 when it is released, and if the circuit is open between
terminals 3 and 4 when the plunger is pushed in to a depth of within 4.5
mm (0.2 inch) from the outer case edge surface.
Q: Is the circuit between terminals 3 and 4 still closed when the plunger is
released or open even with it is pushed in?

3. Turn the ignition switch to the "ON" position.
4. Measure the terminal voltage between special tool 23-pin connector
(without red tape) terminal 33 (PCM connector B-19 terminal 33) and
ground.
When the brake pedal is depressed, the voltage should measure
battery positive voltage (approximately 12 volts). When the brake pedal is released, the voltage should measure 1 volt
or less.

5. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage (approximately 12
volts) when the brake pedal is depressed and 1 volt or less when the brake
pedal is released?
YES : It can be assumed that this malfunction is intermittent. (Refer to
HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
).
Then go to Step 22 .
NO : Replace the PCM. [Refer to POWERTRAIN CONTROL
MODULE (PCM)
]. Then go to Step 22 .
STEP 21. Using scan tool MB991958, read the diagnostic trouble codes.
1. Connect scan tool MB991958 to the data link connector. (Refer to AUTO
-
CRUISE CONTROL SYSTEM DIAGNOSTIC TROUBLESHOOTING STRATEGY
).
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.
