DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
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.
Shift solenoid valve resistance
Between shift solenoid valve-A (No.1) terminal (3)
and transaxle: 11 – 15 Ω at 20 °C (68 °F)
Between shift solenoid valve-B (No.2) terminal (4)
and transaxle: 11 – 15 Ω at 20 °C (68 °F)

Is check results satisfactory?
3 Check shift solenoid valve circuit for ground short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals "C06-
16" (for shift solenoid valve-A (No.1)) or "C06-15" (for
shift solenoid valve-B (No.2)).
3) If connection is OK, check continuity between terminal
"C06-16" (for shift solenoid valve-A (No.1)) or "C06-15"
(for shift solenoid valve-B (No.2)) of disconnected
harness side TCM connector and ground.
Is continuity indicated?

No
Go to "A/T System
Check".
Replace applicable shift
solenoid valve or valve
body harness.
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.
