DTC P0692:00 [MZ-CD 1.6 (Y6) (EURO5 emission level)]

DTC P0692:00	Cooling fan control circuit high
DETECTION CONDITION	• The PCM monitors the cooling fan control signal circuit at PCM terminal 1AI. If the PCM detects that short to power supply in cooling fan control signal circuit, the PCM determines that there is a cooling fan control circuit problem.
POSSIBLE CAUSE	• Fan control module connector or terminal malfunction • PCM connector or terminal malfunction • Short to power supply in the wiring harness between fan control module terminal 1C and PCM terminal 1AI • Fan control module malfunction • PCM malfunction

DTC P0692:00

Cooling fan control circuit high

DETECTION CONDITION

• The PCM monitors the cooling fan control signal circuit at PCM terminal 1AI. If the PCM detects that short to power supply in cooling fan control signal circuit, the PCM determines that there is a cooling fan control circuit problem.

POSSIBLE CAUSE

• Fan control module connector or terminal malfunction

• PCM connector or terminal malfunction

• Short to power supply in the wiring harness between fan control module terminal 1C and PCM terminal 1AI

• Fan control module malfunction

• PCM malfunction

STEP	INSPECTION	ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
No	Go to the next step.
3	INSPECT FAN CONTROL MODULE CONNECTOR CONDITION • Switch the ignition to OFF. • Disconnect the fan control module connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 6.
No	Go to the next step.
4	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 6.
No	Go to the next step.
5	INSPECT FAN CONTROL SIGNAL CIRCUITS FOR SHORT TO POWER SUPPLY • Fan control module and PCM connectors are disconnected. • Switch the ignition to ON (engine off). • Measure the voltage at fan control module terminal 1C (wiring harness-side). • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to the next step.
No	Replace the cooling fan component, then go to the next step. (See COOLING FAN COMPONENT REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)
6	VERIFY THAT DTC P0692:00 TROUBLESHOOTING IS COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Run the vehicle under the FREEZE FRAME DATA stored condition. • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6) (EURO5 emission level)].) Go to the next step.
No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE • Perform the after repair procedure. (See AFTER REPAIR PROCEDURE [MZ-CD 1.6 (Y6) (EURO5 emission level)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZ-CD 1.6 (Y6) (EURO5 emission level)].)
No	DTC troubleshooting completed.

STEP

INSPECTION

ACTION

VERIFY FREEZE FRAME DATA HAS BEEN RECORDED

• Has the FREEZE FRAME DATA been recorded?

Yes

Go to the next step.

Record the FREEZE FRAME DATA on the repair order, then go to the next step.

VERIFY RELATED REPAIR INFORMATION AVAILABILITY

• Verify related service repair information availability.

• Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

• If the vehicle is not repaired, go to the next step.

Go to the next step.

INSPECT FAN CONTROL MODULE CONNECTOR CONDITION

• Switch the ignition to OFF.

• Disconnect the fan control module connector.

• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).

• Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 6.

Go to the next step.

INSPECT PCM CONNECTOR CONDITION

• Disconnect the PCM connector.

• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).

• Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 6.

Go to the next step.

INSPECT FAN CONTROL SIGNAL CIRCUITS FOR SHORT TO POWER SUPPLY

• Fan control module and PCM connectors are disconnected.

• Switch the ignition to ON (engine off).

• Measure the voltage at fan control module terminal 1C (wiring harness-side).

• Is there any voltage?

Yes

Repair or replace the wiring harness for a possible short to power supply, then go to the next step.

Replace the cooling fan component, then go to the next step.

(See COOLING FAN COMPONENT REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)

VERIFY THAT DTC P0692:00 TROUBLESHOOTING IS COMPLETED

• Make sure to reconnect all disconnected connectors.

• Clear the DTC from the PCM memory using the M-MDS.

• Run the vehicle under the FREEZE FRAME DATA stored condition.

• Is the same DTC present?

Yes

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the PCM.

(See PCM REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6) (EURO5 emission level)].)
