CHECKING A SHORT-CIRCUIT IN CAN CABLES

Connect an ohmmeter between the relevant CAN cable (CAN-L and CAN-H) and the power supply, and between the CAN cable and ground. Twist the connectors and turn the cable harness to different positions at each reading to determine any intermittent short-circuits.

Take the following readings

  1. The resistance between CAN-L and ground
  2. The resistance between CAN-L and voltage
  3. The resistance between CAN-H and ground
  4. The resistance between CAN-H and voltage.

The resistance must be infinite or very high in all cases (greater than 1 Mohms).

HINT: The reading can be taken from the same connector if the CAN cables, power supply and ground are exposed. If possible, take readings on the rear of the connector to prevent damage to the terminals in the connector. If this is not possible, use the adapter wiring or loose terminal pins to obtain a good contact.

Was a fault detected?

  1. YES Refer to «IDENTIFYING FAULT CAUSES IN THE CAN NETWORK»(ref-476773-S17838683002012060500000)
  2. NO Refer to «CHECKING THE TRAFFIC LOAD ON THE CAN CABLES»(ref-476773-S30866593022012060500000)

CHECKING THE TRAFFIC LOAD ON THE CAN CABLES

  1. Connect the battery
  2. Ignition on Also read: «BATTERY, DISCONNECTING»(ref-476746-S00156360512012060500000) Faults in the CAN network may be due to a control module sending faulty messages that disrupt "normal" communication. When messages are sent incorrectly, this results in a considerable increase in the amount of traffic on the CAN network. Check the load by measuring the average voltage value on the CAN cables in relation to ground. Connect a voltmeter between CAN-L and ground. The voltage must be approximately 2.3 V. Then connect a voltmeter between CAN-H and ground. The voltage must be approximately 2.8 V. HINT: If possible measure from the rear of the affected connectors so that they are not damaged.

Is the value OK?

  1. YES Refer to «INFORMATION»(ref-476773-S19597597512012060500000)
  2. NO Refer to «IDENTIFYING A CONTROL MODULE IN THE CAN NETWORK»(ref-476773-S32742804032012060500000)

IDENTIFYING FAULT CAUSES IN THE CAN NETWORK

  1. Disconnect a control module that disconnects the CAN network (a control module that has four terminals to the CAN network). HINT: For the low speed network, suitable places for disconnecting the network are at the steering wheel module (SWM), the driver information module (DIM) or the climate control module (CCM). In the event of a short-circuit between one of the CAN cables and voltage or ground, the fault can be located by disconnecting a control module that disconnects the CAN network. Readings can then be taken to determine on which side of the disconnected control module the fault is located. Connect an ohmmeter between the CAN cable and supply voltage or ground. Take readings at both ends of the CAN network where the network is disconnected. Twist and bend the cable harness to locate any intermittent short-circuits. The resistance must be infinite or very high (greater than 1Mohms). If a fault can be localized in one direction, disconnect the network at a point further down on the CAN network in the direction in which the fault was discovered and repeat the reading. In this way, try to identify where in the network the fault might be located. HINT: A short-circuit between the CAN cables and supply voltage or ground may be in either the wiring or in a control module. Rectify the wiring as necessary. Replace the control module if the fault has been localized to a control module.

  1. Connect the battery Also read: «BATTERY, DISCONNECTING»(ref-476746-S00156360512012060500000)
  2. Ignition on If the load on the CAN network is too high, this may be due to a control module sending faulty messages on the CAN network (known as a disruptive control module). The fault may also be due to an intermittent short-circuit to supply voltage or ground in one of the CAN cables. This results in the control modules on the CAN network starting to send faulty messages. The faults can occur without a diagnostic trouble code (DTC) being stored by the control modules. The voltage can be measured between the CAN cables in order to check the load on the CAN network. Connect a voltmeter between the CAN cables. If the communication on the network is correct, the average voltage value should be approximately 0.5 V (0.4 V to 0.6 V). If there is a fault in the communication, the voltage reading will be approximately 0.7 V or higher. In order to identify from which control module the faulty communication is being transmitted, cut the supply voltage to one control module at a time and check the voltage in the CAN cables again. The easiest way to cut the supply voltage is to remove a fuse. Repeat until the voltage between the CAN cables drops to approximately 0.5 V. HINT: When the probable faulty control module has been identified, connect and disconnect the supply voltage to the control module a number of times to verify that the fault appears and disappears. NOTE: Do not cut the power to the central electronic module (CEM) unless it is the last control module left to check. The control module that is communicating incorrectly must be replaced. Remedy as necessary. NOTE: Following a fault involving "disruptive" control modules, other modules may remain in "Limp-Home mode" even after switching the ignition off and on a number of times. To remedy this, disconnect and reconnect the battery negative terminal to restore the control modules to normal function.
  1. Continue Refer to «VERIFICATION»(ref-476773-S10391567762012060500000)
  1. Disconnect a control module that disconnects the CAN network (a control module that has four terminals to the CAN network). HINT: For the low speed network, suitable places for disconnecting the network are at the steering wheel module (SWM), the driver information module (DIM) or the climate control module (CCM). In the event of an open-circuit or a short-circuit between the CAN cables, the fault can be localized by disconnecting a control module that disconnects the CAN network. Readings can then be taken to determine on which side of the disconnected control module the fault is located. Connect an ohmmeter between the CAN cables. Take readings at both ends of the CAN network where the network is disconnected. Twist and bend the cable harness to locate any intermittent short-circuits. The resistance must be 120 ohm. If a fault can be localized in one direction, disconnect the network at a point further down on the CAN network in the direction in which the fault was discovered and repeat the reading. In this way, try to identify where in the network the fault might be located. Remedy the cables as necessary.
  1. Continue Refer to «VERIFICATION»(ref-476773-S10391567762012060500000)

HINT: After carrying out the repair, check that the fault has been remedied.

  1. Reinstall the connectors, components, etc.
  2. Ignition on
  3. Erase diagnostic trouble codes using the VCT2000 (or appropriate scan tool)
  4. Start the car. Allow the car to run for 10 minutes.
  5. Read off diagnostic trouble codes (DTCs). Check if a diagnostic trouble codes (DTCs) for communication fault recurs in the central electronic module (CEM).

Does the diagnostic trouble code (DTC) recur?

  1. YES Refer to «INFORMATION»(ref-476773-S12061758672012060500000)

TAKING READING ON CABLE IN THE CAN NETWORK (HS-CAN)

  1. Disconnect the battery negative lead.
  2. Connect the breakout box with the engine control module (ECM) connected. HINT: Where a breakout box cannot be used, take readings from the rear of the affected connectors if possible. This prevents terminal pins and socket housings being damaged. Take resistance readings across the following terminals. Various readings will be obtained due to the structure of the network. Twist the cable harness and work the connectors at accessible points along the cable harness in order to check whether the resistance changes during each measurement. This method can be used to detect intermittent short-circuits or open-circuits. NOTE: The following resistance readings only measure the main arteries in the high speed network, not the junctions that exist for some control modules. If an open-circuit is suspected in a cable, or a short-circuit is suspected in one of its junctions, the connector at the control module for this junction must be disconnected and the reading taken from there. Take the following readings Measure the resistance between the terminals for HS CAN on the Engine control module (ECM). Resistance must be approximately 60 ohms. Permitted values are approximately 55 - 65 ohms. NOTE: If there is a short-circuit somewhere in the CAN-net the resistance will be 0 ohms. Also measure the resistance between each terminal and supply voltage and ground. The resistance shall be very high. HINT: Any short-circuit detected on the CAN-net may be on the main circuit or on any branching running out to some control modules. If a fault is found, try to disconnect the junction with the fault at a point further forward. Try to locate the fault in this way. Remedy as necessary. Other information see «BATTERY, DISCONNECTING»(ref-476746-S00156360512012060500000) see «CONNECTING THE BREAKOUT BOX»(ref-476691-S30437390172012060500000) see «SIGNAL SPECIFICATION»(ref-476694-S14228516802012060500000) see «CHECKING WIRING AND TERMINALS»(ref-476689-S17655503092012060500000)

Was a fault detected?

  1. YES Refer to «VERIFICATION»(ref-476773-S19096031812012060500000)
  2. NO Refer to «CHECKING THE TRAFFIC LOAD ON THE CAN CABLES»(ref-476773-S39925148452012060500000)
  1. Connect the battery.
  2. Ignition on. Faults in the CAN network may be due to a control module sending faulty messages that disrupt normal communication. When messages are sent incorrectly, this results in a considerable increase in the amount of traffic on the CAN network. Check the load by measuring the average voltage value on the CAN cables in relation to ground. Check as follows: Connect a voltmeter between CAN-L and ground. The voltage should be approx: V Connect a voltmeter between CAN-H and ground. The voltage should be approx: V Other information see «BATTERY, DISCONNECTING»(ref-476746-S00156360512012060500000)

Is the value OK?

  1. YES Refer to «INFORMATION»(ref-476773-S37452092532012060500000)
  2. NO Refer to «IDENTIFYING A CONTROL MODULE IN THE CAN NETWORK»(ref-476773-S13115260232012060500000)

If the load on the CAN network is too high, this may be due to a control module sending faulty messages on the CAN network (known as a disruptive control module). The fault may also be due to an intermittent short-circuit to supply voltage or ground in one of the CAN cables. This results in the control modules on the CAN network starting to send faulty messages. The faults can occur without a diagnostic trouble code (DTC) being stored by the control modules. The voltage can be measured between the CAN cables in order to check the load on the CAN network.

Take the following readings

  1. Connect a voltmeter between the CAN cables. The average value of the voltage must be approximately 0.6-1.4 V. In case of a problem with communication the voltage is considerably higher.
  2. In order to identify which control module has faulty communication, cut the power supply to one control module at a time. Check the voltage in the CAN cables again. The easiest way to cut the power supply is to remove the fuse(s) for the relevant control module. Repeat until the voltage between the CAN wiring drops to the normal level.

Note. When connecting and disconnecting certain control modules, diagnostic trouble codes (DTCs) may be stored in other control modules.

HINT: When the suspected control module has been identified, connect and disconnect the supply voltage to the control module a number of times to verify that the fault appears and disappears. Ignition off between each check.

Note. Do not cut the power to the central electronic module (CEM) unless it is the last control module left to check.

A control module that is communicating incorrectly must be replaced. Remedy as necessary.

Note. Following a fault involving control modules that disrupt communication, other control modules may operate in Limp-Home mode (i. e. they work but with limited functionality) even after switching the ignition off and on a number of times. To remedy this, disconnect and reconnect the battery negative terminal to restore the control modules to normal function.

  1. Continue Refer to «VERIFICATION»(ref-476773-S19096031812012060500000)

HINT: Once a fault has been repaired, conduct a verification to check that the fault has been remedied.

  1. Verification consists of 2 parts. Part 1 is carried out via a test in the workshop. Part 2 is carried out on the road. If the function is determined as incorrect in part 1, then part 2 does not need to be carried out. If the function is determined as being correct in part 1 and the vehicle can be tested on the road, part 2 must be carried out. This is because in certain cases the function can be difficult the check in a workshop environment.
  2. Ignition off
  3. Reconnect the connectors, components, etc.
  4. Start and run the engine to operating temperature.
  5. Read off the shift angle of the camshaft and the desired shift angle of the camshaft to check the function.

Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

HINT: The diagnostic trouble code (DTC) specifies the relevant camshaft.

  1. ECM-P001600: Camshaft inlet, bank 1. Bank 1 (cylinder row nearest the front): cylinders 1, 3, 5 and 7. Bank 2 (cylinder row furthest to the rear, nearest the passenger compartment): cylinders 2, 4, 6, and 8.
  2. ECM-P001700: Camshaft exhaust, bank 1. Bank 1 (cylinder row nearest the front): cylinders 1, 3, 5 and 7. Bank 2 (cylinder row furthest to the rear, nearest the passenger compartment): cylinders 2, 4, 6, and 8.
  3. ECM-P001800: Camshaft inlet, bank 2. Bank 1 (cylinder row nearest the front): cylinders 1, 3, 5 and 7. Bank 2 (cylinder row furthest to the rear, nearest the passenger compartment): cylinders 2, 4, 6, and 8.
  4. ECM-P001900: Camshaft exhaust, bank 2. Bank 1 (cylinder row nearest the front): cylinders 1, 3, 5 and 7. Bank 2 (cylinder row furthest to the rear, nearest the passenger compartment): cylinders 2, 4, 6, and 8.
  1. Start the engine.
  2. Read off the adaption for the camshaft, the camshaft shift angle and desired value for the camshaft shift angle. Check that the read off values correspond to the guide values below. The difference between the camshaft shift angle and desired value for camshaft shift angle can be read off from the lower digital display. Note the read off values as a basis for continuing fault-tracing. Adaption camshaft Inlet camshaft: 75° CA (camshaft angle) (+/-8° CA) Exhaust camshaft: 120° CA (+/-8° CA) Camshaft shift angle The difference from the desired value of the camshaft shift angle (inlet and exhaust): approximately 8° CA The fault is permanent if the values are not correct. If the values are correct, this indicates that the fault is intermittent and not presently active.
  1. Continue Refer to «CHECKING COMPONENTS»(ref-476773-S14712299242012060500000)

HINT: Incorrect function on the camshaft reset valve is probably the cause of this diagnostic trouble code (DTC) if

  1. The adaption value and camshaft shift angle are correct in the previous check (intermittent fault).
  2. The adaption value is correct but the camshaft shift angle is incorrect in the previous check.

HINT: Contaminants in the engine oil can damage components in the camshaft control which can cause function faults.

Check the engine oil grade. Check especially for contaminants.

Check the default settings of the camshafts.

Remove the camshaft reset valve, check the reset valve and the oil ducts in the cylinder head. Check for contaminants and blockages.

Try a new camshaft reset valve if no fault is found or if the above remedies do not rectify the fault.

HINT: The fault can also be caused by a damaged variable valve timing (VVT) unit.

HINT: After carrying out the repair, check that the fault has been remedied.

HINT: In order to verify this diagnostic trouble code (DTC), adaptation of the camshaft must be completed. Adaptation of the camshaft is carried out by the engine control module (ECM) when the engine is at operating temperature, during engine braking (fuel shut-off) above 1500 RPM for at least 10 seconds.

CAUTIONTest driving on the road must be carried out on a road with minimal traffic. Follow the highway code.
  1. Ignition off
  2. Reconnect the connectors, components, etc.
  3. Start and run the engine to operating temperature.
  4. Drive the vehicle on the road. Ensure that the conditions for camshaft adaptation are met: engine braking (fuel shut-off) above 1500 RPM for at least 10 seconds. The conditions can be satisfied for example by driving the vehicle with a high engine load (accelerating) up to approximately 90 km/h and then releasing the accelerator pedal for 10 seconds. NOTE: In order for the adaptation to be carried out, the accelerator pedal must not be touched during engine braking.
  5. Repeat the schedule to ensure that the diagnosis and adaptation are carried out.
  6. Connect VCT2000 (or appropriate scan tool) to the data link connector without switching off the engine.
  7. Read the diagnostic status and fault status for the diagnostic trouble code by selecting the diagnostic trouble code in the list. NOTE: If the engine is switched off, the stored fault status will be erased and the test drive will have to be repeated. Check that the diagnostic status for the diagnostic trouble code (DTC) is "Completed". When the diagnostic status for the diagnostic trouble code (DTC) is "Completed", the engine control module (ECM) has carried out camshaft adaption. If the status is "Not completed" the test drive must be carried out again. If the function is correct, the fault status must be "No fault found" when the diagnostic is complete. Check that the value for camshaft adaption is correct when the diagnostic status for the diagnostic trouble code (DTC) is "Completed". Inlet camshaft: 75° CA (camshaft angle) (+/-8° CA) Exhaust camshaft: 120° CA (+/-8° CA)

Use the following information and general checks during fault-tracing.

Note. Check that the fuses are intact. For locations, see the owner's manual or the cover for fuse box.

  1. Check, if possible, relevant functions in the vehicle using buttons/controls/test drives to determine the status of the fault. NOTE: If the vehicle does not show any of the given symptoms in the diagnostic trouble code information (DTC), this may mean that the fault is intermittent or that the control module is not detecting the fault at this moment.
  2. Use the diagnostic trouble code's frozen values , status identifiers and counter to determine the operating conditions when the fault was detected, the fault's current status and any degree of intermittence of the fault.
  3. Check and fault-trace according to the fault causes that are specified in the diagnostic trouble code (DTC) information .
  4. Use VIDA (Volvo scan tool) . Read off the parameters, activate components and functions, carry out quick tests and checking routines for the diagnostic trouble codes to identify the fault.
  5. Check relevant components according to Component specifications .
  6. Check relevant signals using the appropriate signal specification and breakout box service information.

Remedy as necessary.
