Inspection Procedure 1
COMMENTIf the engine does not crank when the selector lever is in "P" or "N" position, the cause is probably a malfunction of Park/Neutral position switch system, transaxle control cable assembly, engine system, torque converter or oil pump.
TROUBLESHOOTING HINTS
The most likely causes for this case:
- Malfunction of the Park/Neutral position switch
- Malfunction of the transaxle control cable assembly
- Malfunction of the engine system
- Malfunction of the torque converter
- Malfunction of the oil pump
- Malfunction of the PCM
DIAGNOSIS
Required Special Tool: MB991502: Scan Tool (MUT-II)
CAUTION: To prevent damage to scan tool MB991502, always turn the ignition switch to "LOCK" (OFF) position before connecting or disconnecting scan tool MB991502.
STEP 1. Is A/T Diagnostic Trouble Code Numbers "27" Or "28" Displayed?
1. Connect scan tool MB991502 to the data link connector.
2. Turn the ignition switch to "ON" position.
3. Check whether A/T diagnostic trouble code number "27" or "28" resets.
If yes, refer to Code number 27 or 28 - Park/Neutral position switch system.
If no, go to Step 2.
STEP 2. Check The Transaxle Control Cable Assembly.
Move the selector lever to each position, and check if the manual control lever position of the Park/Neutral position switch corresponds to the selector lever position.
If the manual control lever position is correct, go to Step 3.
If the manual control lever position is not correct, repair the transaxle control cable. Refer to Park/Neutral Position Switch and Control Cable Adjustment. Confirm that the manual control lever position is correct.
STEP 3. Check The Engine.
Refer to <2.4L Engine>, Diagnosis - Symptom Chart - Starting or <3.0L Engine>, Diagnosis - Symptom Chart - Starting.
If the inspection result is not good, repair or replace the appropriate engine components.
If the inspection result is good, go to Step 4.
STEP 4. Check The Torque Converter.
Remove the transaxle.
Check the torque converter for installation condition (whether installed in a slanted direction or not), its spline or its teeth for damage.
If the torque converter is good, go to Step 5.
If the torque converter is not good, repair or replace it.
STEP 5. Replace The Oil Pump.
Replace the oil pump (Oil pump cannot be repaired). Confirm that the malfunction symptom is eliminated.
If the symptom is eliminated, diagnosis is complete.
If the symptom is not eliminated, go to Step 6.
STEP 6. Replace The PCM.
Replace the PCM. The immobilizer-ECU and the ignition key should be replaced together with it. Refer to Ignition Switch and Immobilizer System - Ignition Switch and Immobilizer System. Confirm that the malfunction symptom is eliminated.
If malfunction is eliminated, diagnosis is complete.
