DTC P0758 (DTC NO.23/24) SHIFT SOLENOID-B (NO.2) ELECTRICAL

DTC P0743 (DTC NO.25/26) TCC (LOCK-UP CLUTCH) SYSTEM ELECTRICAL

1. Shift solenoid-A (No.1)
2. Shift solenoid-B (No.2)
3. TCC (lock-up) solenoid
DTC DETECTING CONDITION
• Solenoid output voltage too high although TCM orders solenoid to turn OFF.
• Solenoid output voltage too low although TCM orders solenoid to turn ON.
Step
1 1) Turn ignition switch OFF and disconnect
solenoid coupler.
2) Measure the resistance between each sole-
noid terminal of the solenoid side coupler
and transmission ground.
Is it 11 – 15 Ω?
(See figure.)
2 Is DTC No.22, 24 or 26?
3 Is DTC No.21, 23 or 25?
4 1) Disconnect TCM couplers.
2) Measure the resistance between terminal
"C44-10", "C44-23" or "C44-22" of the dis-
connected harness side TCM coupler and
body ground.
Is it about 0 Ω?
(See figure.)

5. TCM coupler (viewed from harness side)
Action
AUTOMATIC TRANSMISSION (4 A/T) 7B-35
Yes
Go to Step 2.
Go to Step 4.
Go to Step 6.
"WHT/RED", "WHT/BLU"
or "BRN/YEL" wire
shorted to ground.
No
• Solenoid lead wire
open or shorted to
ground.
• Malfunction of solenoid.
Go to Step 3.
Go to Step 5.
(When DTC is P0753,
P0758 or P0743.)
Substitute a known-good
TCM and recheck.
