F • The bottom line is a battery(-) line or ground(#31).
DRIVER ASSIST
( G : ground )

G • There are a number of cross lines.

A
E A crossing having a dot as in “B ” means that the
BR G lines A and B are connected to each other. On the
other hand, a crossing having no dot indicates that
the lines A and B are separate lines.

F H • This section indicates the body ground Connection.

39. BLINKCODE DESCRIPTION

For blinkcode activation warning lamp respectively the ASR-L has to be grounded for a given
time by a push button switch. Which signal lamp has to be used depends on ECU type respec-
tively its parametersetting. The duration defines the mode. After release of the switch the signal
light will be on for further 0.5 sec. to confirm that the grounding was detected and accepted by
the Electronic Control Unit, ECU.
If a fault occurs or signal lamp is grounded for longer than 6.3 sec. blinkcode will be terminated.
If grounding is detected for more than 15 sec., fault detection of warning lamp open circuit can
be detected and stored in ECU EEPROM (non-volatile memory). Blinkcode activation on ASR-
lamp do not cause fault memorizing because open circuit is not detected.
Dashboard signal lamp check devices which grounds the lamp in the described way acti-
vates the related mode.

1) DIAGNOSTIC MODE
For diagnostic mode activation signal lamp has to be grounded for 0.5 sec. to 3.0 sec.

FC : Faultcode // 1 to 8 // a: first part ; b: second part see Blinkcode List

FC1 repeated because fault is actual

If one fault was detected during current "IGNITION ON" (autual fault) the ECU blinks out that fault. If
more faults were detected during that period blinkcode shows just the latest detected fault. For
termination ignition must be switched off/on or vehicle has to move (measured speed of more than
one axle).

If there is no actual fault, the last fault will be blinked out fist. Further fault numbers may not represent
the sequence of occurrence. The stored fault blink mode is self terminating.

FC : Faultcode // 1 to 8 // a: first part ; b:second part see Blinkcode List

 2. CIRCUIT DIAGRAM BY SYSTEMS

2) SYSTEM MODE, CLEAR

ALL MEMORIZED FAULTS:
System mode is activated if the signal lamp is grounded for a time of 3 to 6.3 sec. All stored faults are
erased, if no fault is actual.
For termination ignition has to be switched off / on or vehicle has to move (measured speed of more
than one axle).
System code (one number) represents the expected system and should be used to check correct
ECU type. After activating system mode ASR(ATC) is disabled for dyno tests. With WL blinkcode
ECU's ASR(ATC) lamp is permanently on indicating ASR(ATC) disabling.

Two seconds after system mode activation further functions are available:
1. ASR (ATC) engine control function can be tested by two times extra grounding of a time of >0.5 sec
(ASR(ATC) commands idle torque for 10 sec.)
2. ASR(ATC) respectively Retardercontrol system can be reconfigured by three times extra grounding
of a time of > 0.5 sec (missing components can be confirmed).
Reconfiguration is confirmed by four short flashes

Without actual fault : CLEARS ALL MEMORIZED FAULTS

CLEAR ALL is accepted and confirmed by 8 short flashes followed by the system code.

Without actual fault

Identical to no actual fault condition but CLEAR ALL is not accepted.

System : 2 x 4S/4M 6 x 4S/3M (VAR rear)

3 x 4S/3M (MAR/VAR front) 7 x 4S/2M (VAR both)

2. CIRCUIT DIAGRAM BY SYSTEMS

3) ENGINE CONTROL FUNCTION TEST:

For testing engine control function a 10 sec idle torque can be commanded if the signal lamp is
additionally two times grounded. The duration of grounding has to be longer than 0.5 sec. and time
between the two grounding has to be less than 3 sec.
The 10 sec. time starts 3 sec. after last grounding. Parallel to the engine control function test the
system blinkout continues.

4) RECONFIGURATION:
- The ECU modifies its default system (without ASR/ATC) to ASR/ATC if a differential brake valve and
one of the engine control interfaces are connected.
- Connected SAE J1939 (SAE J 1922) without a differential brake valve cause an extension of the
supervised ABS components.
- Connected endurance brake relay (DBR output) or received retarder messages on data link
(SAE J1922 resp. SAE J1939) stores and extends the ABS components too.

Without reconfiguration such ECU'S could not be used in vehicles without those components. Additional
to diagnostic tools this reconfiguration can be done by the means of blinkcode.
To avoid unintentional reconfiguration this function has to be confirmed by three times grounding of
the signal lamp in the way described above for engine control function test. Before system code
continues 4 short flashes confirm the modification of parameters.

The ASR/ATC lamp bulbtest duration shows whether ASR/ATC is configured or not. Without ASR/
ATC:1,5 sec. ;with ASR/ATC 3 sec. (as Warning Lamp).

5) DYNOTESTER FUNCTION:

For certain dynotester it is necessary to disable ASR/ATC to allow higher speed difference between
driven and steering axle. By activating system mode ASR/ATC can be disabled. With WL Blinkcode
ECU's ASR(ATC) lamp is permanently on indicating ASR(ATC) diabling.
To prevent dangerous situations caused by brakeforce in case of ignition off/on or powersupply inter
rupts, ASR/ATC is disabled as long as there are speed differences after ECU reset. For indication the
ASR/ATC lamp is permanently on until ignition is switched off/on.

7) FAULTCODES / REPAIR INSTRUCTIONS

2. n Check modulator wires. Inlet(EV) or outlet(AV) or common wire is permanently or

temporarily broken or shorted to plus respectively ground.

3. n Amplitude of sensorsignal is to low. Check bearing play, polewheel run out, push sensor
to polewheel. Check sensor wiring and connectors for intermittent contact. Other possible
reason:gear engaged at slippery conditions. 16 sec. slip duration.

4. n Check sensor wiring. Open circuit, short circuit to plus respectively ground or between
sensorwires IG/IGM is detected

5. n Check sensor wiring and connectors for intermittent contact. Check toothed wheel for
damages. Check for mismatch-fault of another sensor. Pneus or number of polewheel
teeth are different.
Check polewheel for damages/missing teeth/run out. Use WABCO sensor probe. Replace
6. n
polewheel if not checked o. k. If additional airgap faults are stored, adjust airgap.
ECU with PROP : Check wire and speedometer signal. C3/B7 signal calibration, check
7-1
tyre sizes.
Gear switch signals neutral or is manipulated.
Electronic engine control: Check wiring respectively other ECU's
Excessive slip / dynotester ? One axle was much faster than other?
7-2 Check wire. Output wire is interrupted or grounded or shorted to battery supply.
7-3 Check wire. Output wire is interrupted or grounded or shorted to battery supply.
ECU with SAE J1922 resp. SAE J1939:Check other ECU's. No access to the link
7-4 Check wire and bulb. Was blinkcode switch activated longer than 16 s?
7-5 Check wires resp. parametersetting. Diff-brake valve without engine control is detected or
CAN, PWM, PROP are detected while selfparameterizing is disabled.
7-6 Check wire. Output wire is interrupted or shorted to ground or battery supply.
7-7 Check brake sensor wiring. Intput wire is interrupted or shorted to ground or battery supply.
8-1 Check supply wire and fuse. Supply voltage is temporarily too low
8-2 Check alternator and battery. Supply voltage too high for more than 5 sec.
8-3 Replace ABS(ASR) electronic if fault detection repeats.
8-4 No modulators connected or wrong ECM or wrong parameterized
8-5 Check ECU ground wires and common modulator wires
