Mitsubishi Outlander GS45X. Manual - part 1620

DIAGNOSIS

TSB Revision

CVT

23A-37

.

DIAGNOSTIC FUNCTION

TCM monitors the signal from the transmission range 
switch, and determines if the abnormal input is 
present or not.

.

DESCRIPTIONS OF MONITOR METHODS

• TCM does not detects the inhibitor switch input 

signal for 5 seconds when the vehicle speed is 1 
km/h (0.6 mph) or more for 10 seconds continu-
ously.

• TCM detects the multiple inputs from the trans-

mission range switch for 2 seconds.

.

MONITOR EXECUTION

• Vehicle speed (no-transmission range switch sig-

nal input):1km/h (0.6 mph) or more for 10 sec-
onds continuously

• Vehicle speed (transmission range switch signal 

multiple input) : No conditions

• Throttle valve opening : 1/8 or more

• Engine speed : 450 r/min or more

DTC SET CONDITIONS

Check Conditions

• Vehicle speed over 1 km/h (0.6 mph): 10 seconds 

or more.

• Throttle position sensor voltage: 1.37 volts or 

more.

• Engine speed: 450 r/min or more.

• Voltage of battery: 9 volts or more.

• Voltage of battery: 16 volts or less.

JUDGMENT CRITERIA

• Transmission range switch: multiple signal. (2 

seconds)

• Transmission range switch: no signal. (5 sec-

onds)

.

OBD-II DRIVE CYCLE PATTERN

transmission range: D (Drive the vehicle for 10 sec-
onds or more while the accelerator opening angle is 
20% or more)

.

PROBABLE CAUSES

• Malfunction of the transmission range switch

• Improper adjustment of transaxle control cable

• Damaged wiring harness and connectors

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III data list
Item 49: Transmission range switch
Check that the service data changes when the selector lever is 
moved to all ranges.

OK: The service data changes in response to the 
selector lever operation.

Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Go to Step 2.

STEP 2. Check the following connector:

• B-110 transmission range switch connector

• C-37 TCM connector

Check the terminals for a contact status problem and internal 
short circuit.
Q: Is the check result normal?

YES : Go to Step 3.
NO :  Repair the defective connector.

STEP 3. Check for open circuit in wiring harness between 
the ETACS-ECU connector and the transmission range 
switch connector
Between the C-313 ETACS-ECU connector (terminal No.4) and 
the B-110 transmission range switch connector (terminal No.3)
NOTE: Prior to the wiring harness inspection, check the inter-
mediate connectors C-129 and A-13, and repair that if neces-
sary.
Q: Is the check result normal?

YES : Go to Step 4.
NO :  Repair the wiring harness.

STEP 4. Check for open circuit in the wiring harness 
between the transmission range switch connector and the 
TCM connector

• Between B-110 transmission range switch connector (termi-

nal No.2) and C-37 TCM connector (terminal No.32)

• Between B-110 transmission range switch connector (termi-

nal No.5) and C-37 TCM connector (terminal No.45)

• Between B-110 transmission range switch connector (termi-

nal No.8) and C-37 TCM connector (terminal No.34)

• Between B-110 transmission range switch connector (termi-

nal No.9) and C-37 TCM connector (terminal No.33)

Q: Is the check result normal?

YES : Go to Step 5.
NO :  Repair the wiring harness.

STEP 5. Transmission range switch and control cable 
adjustment
Refer to 

P.23A-144

.

Q: Is the check result normal?

YES : Go to Step 6.
NO :  Adjust the transmission range switch and control 

cable.

STEP 6. Transmission range switch continuity check
Refer to 

P.23A-143

.

Q: Is the check result normal?

YES : Go to Step 7.
NO :  Replace the transmission range switch.

STEP 7. Symptom recheck after erasing diagnostic trouble 
code
Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Replace TCM.
