STEP 2. Check the transmission range switch.
Measure the resistance between the terminals for each trans-
mission range as indicated in the table below.
NOTE: For vehicles with sport mode, four positions (P, R, N, D)
are used.
Q: Does the resistance measure less than 2 ohms for each
transmission range?
YES : Go to Step 3.
NO : Replace the transmission range switch. Refer to

STEP 3. Check intermediate connector A-13, transmission
range switch connector B-110, joint connector (1) C-01 and
junction block connector C-214 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Are the connectors and terminals in good condition?
YES : Go to Step 4.
NO : Repair or replace the damaged components. Refer to

STEP 4. Check harness for open or short circuit to ground
between transmission range switch connector B-110
terminal 8 and junction block connector C-214 terminal 12.
Q: Is the harness wire in good condition?
YES : Go to Step 5.
NO : Repair or replace the harness wire.
STEP 5. Using scan tool MB991958, check data list item
61:Transmission Range Switch.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to "ON" position.
(3) Set scan tool MB991958 to the data reading mode.
• Item 61: Transmission Range Switch.
• Move the selector lever to "P," "R," "N," "D," "3," "2,"
"L" and sport mode positions and confirm that the
selected transmission range match the positions
shown on scan tool MB991958. (Vehicles with sport
mode is indicated as "D" on the scan tool).
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the switch operating properly?
YES : It can be assumed that this malfunction is
intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
− How to
Cope with Intermittent Malfunction
NO : Replace the PCM.
