DTC P0692:00 [MZ-CD 1.6]

id0102g8069200

DTC P0692:00

Cooling fan control relay No.1 control circuit high
DETECTION CONDITION
•  The PCM monitors the cooling fan relay No.1 control signal. If the voltage at PCM terminal 312 remains high for 0.5 s. while the cooling fan relay No.1 control circuit is actuated, the PCM determines that there is a cooling fan relay No.1 control circuit short to power supply.
POSSIBLE CAUSE
•  Cooling fan relay No.1 terminal malfunction
•  Cooling fan relay No.1 malfunction
•  PCM connector or terminal malfunction
•  Short to power supply in the wiring harness between cooling fan relay No.1 terminal E and PCM terminal 312
•  PCM malfunction

Diagnostic procedure

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 COOLING FAN RELAY NO.1 TERMINAL CONDITION
•  Remove the cooling fan relay No.1.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminals, then go to Step 7.
No
Go to the next step.
4
INSPECT COOLING FAN RELAY NO.1
•  Inspect the cooling fan relay No.1.
•  Is there any malfunction?
Yes
Replace the cooling fan relay No.1, then go to Step 7.
No
Go to the next step.
5
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 7.
No
Go to the next step.
6
INSPECT COOLING FAN RELAY NO.1 CONTROL SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Cooling fan relay No.1 and PCM connectors are disconnected.
•  Switch the ignition to ON (engine off).
•  Measure the voltage at the cooling fan relay No.1 terminal E (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
Go to the next step.
7
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.
Go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the after repair procedure.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6].)
No
DTC troubleshooting completed.
