DTC DETECTING CONDITION
• Solenoid output voltage too high or too low differently from TCM order.
Step Action Yes No
1 1) Turn ignition switch OFF and disconnect sole-
noid coupler.
2) Measure resistance between terminal of sole-
noid coupler and transmission ground. (See
figure.)
Is it 2.0 – 4.0
Ω
?
Go to Step 2. • Solenoid lead wire open or
shorted to ground.
• Malfunction of solenoid
valve.
2 1) Disconnect TCM couplers.
2) Measure resistance between terminal of dis-
connected body side solenoid coupler and
terminal “E13-11”, “E13-12” or “E13-13” of
disconnected harness side TCM coupler.
(See chart.)
Is it 6.5 – 8.5
Ω
?
Go to Step 3. Inspect dropping resister refer-
ring to “DROPPING RESIS-
TOR” in this section.
If OK, circuit between TCM
and dropping resister or drop-
ping resister and solenoid cou-
pler open.
3 Check continuity between terminal “E13-24”,
“E13-25” or “E13-26” of disconnected TCM cou-
pler and terminal of disconnected body side sole-
noid coupler. (See chart.)
Is there continuity? Go to Step 4. Circuit between TCM and sole-
noid coupler open.
