DTC P2530 IGNITION SWITCH RUN POSITION CIRCUIT

DTC detecting condition:

Immediately at fault recognition

Trouble symptom:

Faulty TCM operation

CAUTION:

Use the check board when measuring the TCM terminal voltage and resistance.

Wiring diagram:

CVT control system CVT Control System">

STEP	CHECK	YES	NO

1.CHECK CONNECTOR.

Check the installing condition of TCM connector.

Is the TCM connector installed properly?

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2530 IGNITION SWITCH RUN POSITION CIRCUIT">Go to Step 2.

Install the TCM connector.

2.CHECK INPUT VOLTAGE OF TCM.

1) Turn the ignition switch to OFF.

2) Disconnect the TCM connector.

3) Turn the ignition switch to ON.

4) Measure the voltage between TCM connector and chassis ground. (While wiggling the harness)

Connector & terminal

(B54) No. 41 (+) — Chassis ground (−):

Is the voltage 8 V or more?

Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

NOTE:

In this case, the following items may be the cause of fault.

• Open circuit or short circuit to ground of harness between TCM connector and ignition switch connector (IG relay 1 connector for model with push button start)

• Poor contact of ignition switch connector (IG relay 1 connector for model with push button start)

• Poor contact of ignition switch (IG relay 1 for model with push button start)

Repair the harness and connector.

NOTE:

In this case, repair the following item:

• Open circuit or short circuit to ground of harness between TCM connector and ignition switch connector (IG relay 1 connector for model with push button start)

• Poor contact of ignition switch connector (IG relay 1 connector for model with push button start)

• Poor contact of ignition switch (IG relay 1 for model with push button start)

1. OUTLINE OF DIAGNOSIS

• Detect the malfunction of ignition SW circuit.

• Judge as NG if the ignition SW signals are lost 5 times or more even though the engine is ON.

2. EXECUTION CONDITION

Secondary parameters	Execution condition
12 V battery system voltage	≥ 10.9 V
Engine speed	≥ 400 rpm

3. 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
Count of temporarily discontinuous input of ignition switch	≥ 5 count

Time Needed for Diagnosis: 5 seconds

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