Is DTC P0970 or P0971 indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the CVT clutch pressure control solenoid valve and the TCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.?
2.
Determine possible failure area (TCM, short in CPCLS line, open in CPCLS/CPC+ line):

?1.
Turn the vehicle to the OFF (LOCK) mode.
?2.
Disconnect the following connector.
TCM 50P connector
?3.
Measure the resistance between test points 1 and 2.
Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good TCM, then recheck. If this DTC goes away and the TCM was substituted, replace the original TCM.?
