DIAGNOSIS CODE SET CONDITIONS

If a status continues with which the clutch control solenoid No.2 current differs from the A/T-ECU target value (1 drive cycle), code No.P0969 is set.

PROBABLE CAUSES

Malfunction of valve body (clutch control solenoid No.2)
Damaged harness wires and connectors
Malfunction of the A/T-ECU

DIAGNOSIS PROCEDURE

STEP 1. Measure the resistance at A/T control solenoid valve assembly connector C-06.

Disconnect the connector, and measure the resistance between terminal No.6 and No.13 at the solenoid side.

OK: 5.0 - 5.6 Ω (A/T fluid temperature 20°C)

Q. Is the check result normal?

	Go to Step 3.

	Go to Step 2.

STEP 2. Check for open circuit, short circuit and harness damage in SL2, SL2G line between A/T control solenoid valve assembly connector and line pressure control solenoid.

Q. Is the check result normal?

	Go to Step 5.

	Repair or replace the solenoid harness or valve body (clutch control solenoid No.2).

STEP 3. Measure the resistance at A/T-ECU connector.

Disconnect the connector, and measure the resistance between terminal SL2G line and terminal SL2 line at the harness side.

OK: 5.0 - 5.6 Ω (A/T fluid temperature 20°C)

Q. Is the check result normal?

	Go to Step 5.

	Go to Step 4.

STEP 4. Check for open circuit, short circuit and harness damage in SL2, SL2G line between A/T control solenoid valve assembly connector and A/T-ECU connector.

Q. Is the check result normal?

	Go to Step 5.

	Repair the connector(s) or the wiring harness.

STEP 5. Check whether the diagnosis code is set again.

Check again if the diagnosis code is set.

Q. Is diagnosis code No.P0969 set?

	Replace the A/T-ECU.

	Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
