No Gear Shift to 4th Gear

S6JB0A5104020

System Description
TCM does not shift to 4th gear under any of the following condition.
• “3” position switch signal is inputted.
• 4L/N switch (if equipped) is turned ON. (4L or N mode)
• TCM detects the following DTCs.

DTC, P0722, P0752, P0962, P0963, P0973, P0974, P0976, P0977, P1702

Troubleshooting

WARNING

!

 

• When performing a road test, select a place where there is no traffic or possibility of a traffic 

accident and be very careful during testing to avoid occurrence of an accident.

• Road test should be carried out with 2 persons, a driver and tester, on a level road.

 

Step

Action

Yes

No

1

Was “A/T System Check” performed?

Go to Step 2.

Go to “A/T System 
Check”.

2

Check DTC

Is DTC, P0722, P0752, P0962, P0963, P0973, P0974, 
P0976, P0977 or P1702 detected?

Perform DTC Flow to 
repair and retry.

Go to Step 3.

3

ECT check
1) Warm up engine to normal operating temperature.
2) Check ECT monitored by TCM using scan tool.

Is ECT indicated –40 

°

C (–40 

°

F)?

Go to Step 4.

Faulty ECT sensor, its 
circuit or engine cooling 
system. If OK, substitute 
a known-good TCM and 
recheck.

4

“3” position switch signal inspection
1) With ignition switch ON, check voltage between terminal 

“E92-20” of TCM connector and ground under the 
following conditions.

“3” position switch specification
Shift selector lever to “P”, “R”, “N” or “D” range: 2.9 
– 3.8 V
Shift selector lever to “3”, “2” or “L” range: 1.4 – 2.0 
V

Is result as specified?

• For vehicle equipped 

with 4L/N switch, go 
to Step 5.

• For vehicle equipped 

without 4L/N switch, 
substitute a known-
good TCM and 
recheck.

Faulty “3” position 
switch or its circuit. If 
OK, substitute a known-
good TCM and recheck.

5

4L/N switch signal inspection
1) With ignition switch ON, check voltage between terminal 

“E93-4” of TCM connector and ground.

4L/N switch specification
Transfer gear position “4H”: Battery voltage
Transfer gear position “4L” or “N”: 0 – 2 V

Is result as specified?

Substitute a known-
good TCM and recheck.

Faulty 4L/N switch or its 
circuit. If OK, substitute 
a known-good TCM and 
recheck.
