DIAGNOSIS <SHIFT LEVER>

INTRODUCTION

M1225024900022

The shift lever can exhibit any of the following symp-
toms: Impossible to move, or does not work.

The causes of these symptoms could come from: 
incorrect mounting or a component of the shift lever 
may be faulty.

TROUBLESHOOTING STRATEGY

M1225007900029

Use these steps to plan your diagnostic strategy. If 
you follow them carefully, you will find most shift lever 
malfunctions.
1. Gather as much information as possible about the 

complaint from the customer.

2. Verify that the condition described by the 

customer exists.

3. Check the vehicle for any shift lever Diagnostic 

Trouble Codes (DTCs).

4. If you cannot verify the condition and there are no 

DTCs, the malfunction is intermittent. For 
information on how to cope with intermittent 
malfunctions, refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points − How 

to Cope with Intermittent Malfunction 

P.00-15

.

5. If you can verify the condition but there are no 

DTCs, or the system cannot communicate with 
scan tool, refer to the Symptom Chart 

P.22C-370

.

6. If there is a DTC, record the number of the code, 

then erase the code from memory using scan tool.

7. Reconfirm the symptom.
8. If a DTC is set again, go to the Inspection Chart 

for Diagnostic Trouble Codes.

9. If a DTC is not set again, the malfunction is 

intermittent. For information on how to cope with 
intermittent malfunctions, refer to GROUP 00, 
How to Use Troubleshooting/Inspection Service 
Points − How to Cope with Intermittent Malfunction 

P.00-15

.

10.Verify malfunction is eliminated. After repairs are 

completed, the complaint conditions to confirm 
the malfunction has been eliminated.

DIAGNOSIS FUNCTION

M1225000500020

WARNING INDICATOR

When a malfunction occurs to the shift lever, the figure (A) 
remains displayed on the information screen of multi informa-
tion display.
If the figure (A) remains displayed on the information screen of 
multi information display, check whether or not a diagnostic 
trouble code is set.

FAIL-SAFE FUNCTION

If an abnormality occurs to the signal of sensors, 
switches, solenoids, or others, the shift lever-ECU 
performs a control for the driver safety and system 
protection. The control contents are as follows.
