5A-64 Automatic Transmission:
DTC Troubleshooting
Step Action Yes No
1 Was “Automatic Transaxle Diagnostic Flow Table”
performed? Go to Step 2. Go to “A/T System
Check: ”.
2 Check shift solenoid valve resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector (1), (2) on
automatic transmission.
3) Check for proper connection to solenoid at “BRN” (for
shift solenoid valve-A (No.1)) or “BLK/YEL” (for shift
solenoid valve-B (No.2)) circuit.
Check resistance of solenoid valve.

Is check results satisfactory?
Go to Step 3. Replace applicable shift
solenoid valve or valve
body harness.
3 Check shift solenoid valve circuit for ground short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals “C34-
16” (for shift solenoid valve-A (No.1)) or “C34-15” (for
shift solenoid valve-B (No.2)).
3) If connection is OK, check continuity between terminal
“C34-16” (for shift solenoid valve-A (No.1)) or “C34-15”
(for shift solenoid valve-B (No.2)) of disconnected
harness side TCM connector and ground.
Is continuity indicated?
DTC P0973: “BRN”
circuit shorted to
ground.
DTC P0976: “BLK/YEL”
circuit shorted to
ground. Intermittent trouble or
faulty TCM. Check for
intermittent referring to
“Intermittent and Poor
Connection Inspection:
in Section 00”. If OK,
substitute a known-
good TCM and recheck.
