STEP	CHECK	YES	NO

1.CHECK INPUT SIGNAL OF ECM.

1) Turn the ignition switch to OFF.

2) Measure the voltage between ECM connector and chassis ground.

Connector & terminal

(B137) No. 2 (+) — Chassis ground (−):

Is the voltage 10 V or more?

Repair the poor contact of ECM connector.

2.CHECK HARNESS BETWEEN ECM AND MAIN FUSE BOX CONNECTOR.

1) Disconnect the connector from ECM.

2) Measure the resistance between ECM connector and chassis ground.

Connector & terminal

(B137) No. 2 — Chassis ground:

Is the resistance 1 M? or more?

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0560 SYSTEM VOLTAGE">Go to Step 3.

Repair the short circuit to ground in harness between ECM connector and battery terminal.

3.CHECK FUSE NO. 13 (MAIN FUSE BOX).

Is the fuse blown out?

Replace the fuse.

Repair the harness and connector.

NOTE:

In this case, repair the following item:

• Open circuit in harness between ECM connector and battery

• Poor contact of ECM connector

• Poor contact of battery terminal

1. OUTLINE OF DIAGNOSIS

Detect the open/short circuit of back-up power supply circuit.

Judge as NG when the backup power voltage is low.

2. EXECUTION CONDITION

Secondary Parameters	Execution condition
Battery voltage	≥ 10.9 V

3. GENERAL DRIVING CYCLE

Always perform the diagnosis continuously.

4. DIAGNOSTIC METHOD

If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.

Judgment Value

Malfunction Criteria	Threshold Value
Voltage of back-up power supply	≤ 3.5 V

Time Needed for Diagnosis: 2500 ms

Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
