DTC Troubleshooting
Step
1
Was "A/T System Check" performed?
2
Check shift solenoid valve circuit for IG short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at terminal "C06-
16" (for shift solenoid valve-A (No.1)) or "C06-15" (for
shift solenoid valve-B (No.2)).
4) If connection is OK, turn ignition switch ON and measure
voltage 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 it 0 – 2 V?
3
Check shift solenoid valve resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector (1), (2) on
automatic transaxle.
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)
