Q: Does the vehicle accelerate poorly (transaxle stays in 3rd gear) when starting from a stop with the selector lever in "D" range?

YES : Go to Step 2.

NO: Go to Step 5.
STEP 2. Measure the backup power supply voltage at PCM connector C-114 < 2.4L Engine > or C-115 < 3.0L Engine > by backprobing.
1. Do not disconnect connector C-114 < 2.4L Engine > or C-115 < 3.0L Engine >.

2. Measure the voltage between terminal 66 and ground by backprobing.
  - The voltage should measure measured battery positive voltage.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 5.

NO: Go to Step 3.

STEP 5. Using scan tool MB991502, check data list item 61: Transmission Range Switch.
CAUTION: To prevent damage to scan tool MB991502, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991502.
1. Connect scan tool MB991502 to the data link connector.
2. Turn the ignition switch to the "ON" position.
3. Set scan tool MB991502 to data reading mode for item 61: Transmission Range Switch.
  - Move the selector lever to "P," "R," "N," "D," "3," "2," "L" positions and confirm that the selected selector lever positions match the positions shown on the scan tool MB991502.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the switch operating properly?

YES : Check for the symptom. If the symptom is not eliminated, replace the PCM.

NO: Refer to DTCs 27 , 28: Transmission Range Switch System . ,
