Chevrolet Captiva Fault Codes List

The gearbox controller causes a malfunction indicator lamp

Circuit description

The gearbox controller and the ECM are interconnected using a serial data channel. Every 100 milliseconds from the gearbox controller, a P-code is sent to the ECM to report the status and confirm the correct action of the transmission.

If a transmission fault is detected by the gearbox controller, then a P-code is sent from the gearbox controller to the ECM reporting the status, as a result of which the malfunction indicator lamp is turned on and DTC P0700 is set.

Action Taken When the DTC Sets

• The Malfunction Indicator Lamp (MIL) lights up immediately after a malfunction.
• The controller records the operating conditions at the time the fault is detected. This information is stored in the status record buffer and fault logs.
• An archive of diagnostic trouble codes is saved.

Conditions for Clearing the DTC / DTC

• The malfunction indicator lamp goes off after three or four consecutive driving cycles in which the diagnostic did not detect a malfunction.
• The DTC archive is cleared after 40 consecutive heating cycles without malfunctions.
• The diagnostic trouble code can be cleared with a scan tool.
• Power off the ECM for 10 seconds.

Diagnostic information

An intermittent fault can be caused by poor contact, frayed insulation, or a broken wire under the insulation.

Check for poor contact or damaged wiring harness for the engine control module / gearbox. Test the data link circuit for the following:

• Terminal connection
• Locks malfunction
• Warp
• Terminal damage
• Weak contact terminals with wiring connectors.
• Harness Damage

Brake switch circuit 2

Circuit description

The brake switch information is sent to the gearbox controller by the ECM (body controller) via a data network called the controller local area network (CAN). Two circuits are used to exchange CAN data between the ECM and the gearbox controller. A failure in CAN alone does not set the DTC P0703. If a malfunction occurs in CAN, then other codes are set before DTC P0703.

DTC conditions

• Engine is running

Conditions for Setting the DTC

• The brake switch is active and the vehicle speed is greater than 90 km / h.
• The brake light switch is not active when the brake switch is active for 20 seconds.
• Vehicle deceleration for 4 seconds without activating the brake switch.

Action Taken When the DTC Sets

• As soon as an error occurs, the “Perform vehicle maintenance soon” (SVS) indicator lights up.
• The engine control module (ECM) records the operating conditions when faults are detected. This information is stored in the fault logs.
• An archive of diagnostic trouble codes is saved.

Conditions for Clearing the DTC / DTC

• The SVS warning lamp turns off after a trip in which the diagnostic did not detect a malfunction.
• The archive of diagnostic trouble codes is cleared after 20 consecutive heating cycles without malfunctions.
• The diagnostic trouble code can be cleared with a scan tool.
• Power off the ECM for more than 10 seconds.

Clutch pedal sensor circuit 2

Circuit description

The clutch sensor is a switch with normally closed contacts, the clutch pedal is released. The ECM detects the ignition voltage in the clutch sensor circuit when the clutch sensor contacts are closed. The ECM detects 0 volts in the clutch sensor circuit when the clutch sensor contacts open, the clutch pedal is depressed. When the ECM detects a large number of gear changes without detecting a clutch transition, DTC P0833 is set.

DTC conditions

• No braking.
• Vehicle speed above 50 km / h.

Conditions for Setting the DTC

• The ECM must detect 20 or more gear changes without clutch pedal transitions.

Action Taken When the DTC Sets

• As soon as an error occurs, the “Perform vehicle maintenance soon” (SVS) indicator lights up.
• The engine control module (ECM) records the operating conditions when faults are detected. This information is stored in the fault logs.
• An archive of diagnostic trouble codes is saved.

Conditions for Clearing the DTC / DTC

• The SVS warning lamp turns off after a trip in which the diagnostic did not detect a malfunction.
• The archive of diagnostic trouble codes is cleared after 20 consecutive heating cycles without malfunctions.
• The diagnostic trouble code can be cleared with a scan tool.
• Power off the ECM for more than 10 seconds.

Park / Neutral Position Switch Circuit (PNP)

Circuit description

The “Park / Neutral” (P / N) switch is part of the selector switch for the automatic transmission gear selector assembly. The P / N switch is a switch with normally open contacts that close when the gearbox is in the “Parking” or “Neutral” position. The ECM supplies a 12 V reference voltage to the signal circuit of the P / N switch when its contacts are open. When the gearbox switches to the “Parking” or “Neutral” position, the contacts of the P / N switch close and transfer the signal circuit of the P / N switch to ground.

Conditions for Setting the DTC

• Signal mismatch between pin and CAN message

Action Taken When the DTC Sets

• As soon as an error occurs, the “Perform vehicle maintenance soon” (SVS) indicator lights up.
• The engine control module (ECM) records the operating conditions when faults are detected. This information is stored in the fault logs.
• An archive of diagnostic trouble codes is saved.

Conditions for Clearing the DTC / DTC

• The SVS warning lamp turns off after a trip in which the diagnostic did not detect a malfunction.
• The archive of diagnostic trouble codes is cleared after 20 consecutive heating cycles without malfunctions.
• The diagnostic trouble code can be cleared with a scan tool.
• Power off the ECM for more than 10 seconds.

High voltage sensor 2 in the HO2S sensor circuit during a fuel shutdown in engine braking (DFCO)

Circuit description

Using a heated oxygen sensor (HO2S), a voltage is generated that varies between 100-900 mV under normal operating conditions. By means of the ECM, an offset voltage is produced in the signal circuit of the HO2S sensor within 420-480 mV. Basic grounding for the sensor is provided by the ECM. The engine control module (ECM) monitors the signal voltage to determine if the exhaust gas is lean or rich. The oxygen sensor voltage is high when the exhaust gases are enriched, and low when the exhaust gases are depleted. Through the ECM, the HO2S signal is continuously monitored during a closed loop. If the ECM detects a HO2S voltage that is above the set value during the fuel cutoff condition, then DTC is set.

DTC conditions

• The time after fuel cutoff is more than 5 seconds.
• The integrated air mass after fuel cut-off is greater than 15 g.
• The time after dew point temperature is detected is greater than 30 seconds.

Conditions for Setting the DTC

• The filtered voltage of the HO2S sensor is greater than 0.15 V.

Action Taken When the DTC Sets

• The malfunction indicator lamp lights up after 3 confirmed driving cycles.
• The controller records the operating conditions at the time the fault is detected. This information is stored in the status record buffer and fault logs.
• An archive of diagnostic trouble codes is saved.

Conditions for Clearing the DTC / DTC

• The malfunction indicator lamp goes off after three or four consecutive driving cycles in which the diagnostic did not detect a malfunction.
• The DTC archive is cleared after 40 consecutive heating cycles without malfunctions.
• The diagnostic trouble code can be cleared with a scan tool.
• Power off the ECM for 10 seconds.

Throttling is not reached during throttling

Circuit description

The ECM monitors and evaluates the signal voltage of the accelerator pedal position sensors (APP), as well as the input signals of other sensors, to determine the required throttle opening. To control the throttle movement, the ECM supplies a pulse-width modulated (PWM) signal voltage to the throttle actuator motor through the throttle actuator motor control circuit. In addition, the ECM monitors the signal voltage supplied to the throttle actuator motor control circuit. The DTC “Throttle Actuator Motor Control Circuit (TAC)” is set if the ECM detects a condition of malfunction in the TAC circuits or incorrect motor performance.

DTC conditions

• When initializing the throttle actuator.

Conditions for Setting the DTC

• The ECM detects that its internal throttle actuator (TAC) motor driver output does not deactivate after receiving a shutdown command.

Action Taken When the DTC Sets

• The Malfunction Indicator Lamp (MIL) lights up immediately after a malfunction.
• The controller records the operating conditions at the time the fault is detected. This information is stored in the status record buffer and fault logs.
• An archive of diagnostic trouble codes is saved.

Conditions for Clearing the DTC / DTC

• The malfunction indicator lamp goes off after three or four consecutive driving cycles in which the diagnostic did not detect a malfunction.
• The DTC archive is cleared after 40 consecutive heating cycles without malfunctions.
• The diagnostic trouble code can be cleared with a scan tool.
• Power off the ECM for 10 seconds.
