STEP 8. Measure the transmission range switch output
voltage at PCM connector B-21 by using check harness
special tool MB991923. ("N" position)
Measure the voltage between terminal 77 and ground.
• When transmission range is "P," voltage should measure
0.5 volt or less.
• When transmission range is "R," voltage should measure
0.5 volt or less.
• When transmission range is "N," voltage should equal bat-
tery positive voltage.
• When transmission range is "D," voltage should measure
0.5 volt or less.
• When transmission range is "3," voltage should measure
0.5 volt or less. <Vehicles without sport mode>
• When transmission range is "2," voltage should measure
0.5 volt or less. <Vehicles without sport mode>
• When transmission range is "L," voltage should measure
0.5 volt or less. <Vehicles without sport mode>
• When transmission range is sport mode, voltage should
measure 0.5 volt or less. <Vehicles with sport mode>
Q: Is the measured voltage within the specified range?
YES : Go to Step 10.
NO : Turn the ignition switch to the "LOCK" (OFF) position.
Go to Step 9.
