DTC P0699:00

Constant voltage power supply circuit high input

DETECTION CONDITION

•  When the following condition is met, the output voltage of the 5 V power supply terminal exceeds 5.56 V for a continuous 1 s:

MONITORING CONDITIONS

―  Battery voltage: 8—20 V

―  0.5 s have elapsed after the ignition was switched ON (under the engine on or off)

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

•  PCM restricts engine torque.

•  Inhibits the EGR control.

•  PCM controls to fully open the intake shutter valve.

•  Inhibits engine-stop by operating the i-stop function.

POSSIBLE CAUSE

•  Fuel pressure sensor connector or terminals malfunction

•  HP-EGR control valve connector or terminals malfunction

•  LP-EGR control valve connector or terminals malfunction:

•  PCM connector or terminals malfunction

•  Short to power supply in wiring harness between the following terminals:

―  HP-EGR control valve terminal B—PCM terminal 1BE

―  Fuel pressure sensor terminal A—PCM terminal 1AF

―  LP-EGR control valve terminal C—PCM terminal 1AP

•  PCM malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the FREEZE FRAME DATA/snapshot data on the repair order.	—	Go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY RELATED PENDING CODE AND/OR DTC • Switch the ignition off, then ON (engine off). • Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are any other PENDING CODEs and/or DTCs present?	Yes	Go to the applicable PENDING CODE or DTC inspection. (See DTC TABLE [SKYACTIV-D 1.5].)
3		No	Go to the next step.
4	INSPECT FUEL PRESSURE SENSOR CONNECTOR CONDITION • Switch the ignition off. • Disconnect the fuel pressure sensor 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 9.
4		No	Go to the next step.
5	INSPECT HP-EGR CONTROL VALVE CONNECTOR CONDITION • Disconnect the HP-EGR control valve 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 9.
5		No	Go to the next step.
6	INSPECT LP-EGR CONTROL VALVE CONNECTOR CONDITION • Disconnect the LP-EGR control valve 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 9.
6		No	Go to the next step.
7	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 9.
7		No	Go to the next step.
8	INSPECT EACH CONSTANT VOLTAGE POWER SUPPLY CIRCUIT FOR SHORT TO POWER SUPPLY • Verify that the fuel pressure sensor, HP-EGR control valve, LP-EGR control valve connectors are disconnected. • Switch the ignition ON (engine off). • Measure the voltage at the following terminals (wiring harness-side): ― HP-EGR control valve terminal B ― Fuel pressure sensor terminal A ― LP-EGR control valve terminal C • Is the voltage 0 V?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • HP-EGR control valve terminal B—PCM terminal 1BE • Fuel pressure sensor terminal A—PCM terminal 1AF • LP-EGR control valve terminal C—PCM terminal 1AP If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to power supply. Go to the next step.
8		No	Go to the next step.
9	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].) • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].) Go to the next step.
9		No	Go to the next step
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 1.5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 1.5].)
10		No	DTC troubleshooting completed.
