COMPUTER SUPPLY VOLTAGE
PARAMETER
DEFINITIONThis parameter shows the computer feed voltage in volts.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
No faults should be present or stored.
Conformity check with engine stopped and ignition on, engine running, engine coolant
temperature > 80 ˚C
Look for any damage to the wiring and check the condition and connection of the connectors for components 119
and 1337.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the continuity and insulation of the following connections:
●Connection code BP42,
between components 119 and 1337.
●Connection code AP4,
between components 119 and 1337.
Check for + 12 V after ignition feed on connection BP42 of component 119.
Check for + 12 V after ignition feed on connection AP4 of component 119.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for earth on connection N of component 119.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

In the event of a fault, look for any damage to the wiring and check the condition and connection of the connectors
for components 119 and 129.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the continuity and insulation of the following connection:
●connection code 5DU,
between components 119 and 129.
Check for + after ignition feed on connection BP42 of component 119.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

Check for + 12 V on connection BP42 of component 119.
Check for + after ignition feed on connection AP4 of component 119.
Check for earth on connection N of component 119.
Check the insulation and the continuity of the following connections:
●connection code 3MS,
●connection code 3MT,
between components 119 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Run a multiplex network test (see 88B, Multiplex).
If the computer still does not respond, contact the Techline.
AFTER REPAIRDeal with any faults detected by the diagnostic tool. Clear the computer memory.
Carry out a road test, then check with the diagnostic tool.
