Be careful not
to bend the
connector
terminals.
2. Shift Solenoid Valve "A" Inspection
Turn the ignition switch OFF.
Disconnect the shift solenoid "A" 2P (Black) con-
nector.
Measure the resistance between the shift sole-
noid valve 2P (Black) connector terminals of the
solenoid side.
Is the resistance within 14.6 - 16.2 Q (20 C/
68W
YES - GO TO STEP 3.
NO - Faulty shift solenoid valve "A".
3. Shift Solenoid Valve "A" Line Open Circuit
Inspection
Connect the shift solenoid "A" 2P (Black) connec-
tor.
Disconnect the PCM 33P (Black) connector.
Measure the resistance at the PCM connector
terminals.
TOOL:
Test probe 07ZAJ-RDJA110
Connection: A2 - A13
Is the resistance within 14.6 - 16.2 n (20 C/
68°F)?
NO - • Open circuit in the Yellow/black wire.
• Open circuit in the Green/white wire.
YES - GO TO STEP 4.
4. Shift Solenoid "A" Line Short Circuit Inspection
Turn the ignition switch OFF.
Disconnect the shift solenoid "A" 2P (Black) con-
nector.
Check for continuity between the shift solenoid
"A" 2P (Black) connector terminals of the wire
harness side and ground.
Connection: Green/white - Ground
Yellow/black- Ground
Is there continuity?
YES - • Short circuit in the Yellow/black wire.
• Short circuit in the Green/white wire.
NO - GO TO STEP 5.
