7B-34 AUTOMATIC TRANSMISSION (4 A / T)
DTC 22 – SHIFT SOLENOID NO.1
24 – SHIFT SOLENOID NO.2
26 – LOCK-UP SOLENOID
STEP
1 1) Turn ignition switch OFF and disconnect
solenoid coupler.
2) Measure the resistance between each
solenoid terminal of solenoid coupler
and transmission ground.
(See chart and figure below.)
Is it about 12 Ω?
2 1) Disconnect TCM couplers.
2) Measure the resistance between terminal
"A4", "A17" or "A18" of the disconnected
harness side TCM coupler and body ground.
(See figure below.)
Is it about 0 Ω?

NO
D Short in between
solenoid lead wire and
ground.
D Malfunction of shift
solenoid valve.
The cause can be a
"temporary malfunction"
of the TCM.
