Valvetronic, electrical overload protection

Fault description

VVT-Overload Protection (Bank 1)

Condition for fault identification

Test condition:

Electrical overload protection

The engine management monitors the VVT motor’s current

draw. If the monitored current draw exceeds a defined

threshold for several seconds the VVT system is deactivated

(VVT emergency operation mode), and the engine reverts to

throttled operation.

Always active provided that fault codes #10813,#10816,

#10819 are not present.

Terminal condition: none

Voltage condition:

none

Condition for fault memory entry

Warning threshold: 112 掳C DME internal driver circuit

temperature

Deactivation threshold: 126 掳C internal DME driver circuit

temperature

Action in service

1. Check for correct reluctor attachment at VVT sensor.

2. Defective VVT servo motor (for instance, interturn short

205

circuit) Check servo motor and replace as indicated (Clear

fault memory / switch ignition terminals)

3. Check VVT motor wiring harness between VVT motor

and DME for shorts between both VVT motor wires and

vehicle ground.

DME, internal fault: RAM checksum

Fault description

Internal Control Module Non-Volatile Memory (NVMY)

Error

Condition for fault identification

Test condition:

RAM checksum test

This test is executed once, while the control module is

booting.

Terminal condition: Immediately after wakeup in dormant

control module

Voltage condition:

none

Condition for fault memory entry

No debounce. Fault can be reset by clearing fault memory.

Action in service

Start by checking ground connections on the ignition coils.

If these are OK, proceed with the following steps.

Check to determine whether the diagnostic fault code is

stored again after proceeding through the following routine.

If yes: Replace DME.

1. Clear fault memory

2. Ignition off, allow vehicle to assume complete dormant

status

3. Ignition on

4. Read out stored fault codes from fault memory

Valvetronic, position at new start: plausibility

Fault description

VVT-Value Comparison Starting Position/Parking Position

Plausibility (Bank 1)

Condition for fault identification

Test condition:

When the DME is activated (wake-up) it assesses the current

VVT sensor angle based on the last VVT sensor angle prior

to shutdown. If there is a substantial difference in the two

204

angles, the operative assumption will that substantial repairs

have been carried out on the cylinder head. The VVT travel

limit positions must be re-initialized.

No VVT sensor faults should be present (#10800,

#10801,#10802).

Terminal condition: Terminal 15 ON

Voltage condition:

none

Condition for fault memory entry

Following successful travel limit initialization routine (can

be initiated by tester),

active only once at moment when system starts (DME wakeup).

Action in service

Conduct travel limit initialization routine using tester for

activation. Delete stored fault codes from DME fault

memory and initiate dormant vehicle state. Repeat procedure

in case of doubt.

no VVT sensor signal is present) and unit travels to upper

travel limit at 30 % pulse-duty factor for VVT motor.

2. The mass induction airflow is employed as an index to

determine whether the maximum VVT stroke has been

reached.

If the BLS is still OK, the fault will be stored immediately

as soon as the brake pedal is depressed. If the plug is

disconnected the BLS fault will be registered after

approximately 40 sec.

Action in service

1. Check to determine whether foreign matter or objects

(dirt) are causing the switch to hang.

2. Electrical check on wire

a. –> If not OK, repair wire.

b. –> If OK, replace switch.

3. Check by depresssing the brake pedal repeatedly. No fault

Knock-sensor signal 1

Fault description

Knock Sensor 1 Circuit High (Bank 1 or Single Sensor)

Condition for fault identification

Test condition:

Knock sensor signal monitor

Vehicle road operation at >2800 1 rpm (current data status,

tends toward >2560 rpm) and air mass > 180 mg/unit. It is

not possible to clear fault by switching ignition terminals.

Compliance with the activation conditions and absence of

malfunction extending over several seconds are required

before fault code can be cleard.

Terminal condition: Terminal 15, engine on

Voltage condition:

Voltage in onboard electrical system > 10 V

Condition for fault memory entry

Yes, by event counter. If knock sensor signal remains below

threshold (differential knock signal > 4.8 V) for 1…3 sec.

fault code is stored

Action in service

1. Check knock sensor connection to verify that it is tight.

2. Check wire connecting knock sensor 1 and enginemanagement

control module

3. Check for connection between knock sensor 1 and ground

or positive

4. Replace knock sensor
