6VE1 3.5 ENGINE DRIVEABILITY AND EMISSIONS

Service Vehicle Soon (SVS) Lamp “ON” Steady

D06R200111

Circuit description

The Service Vehicle Soon (SVS) lamp is a lamp which
added the function of immobi warning to the Reduced
Power Lamp (RPL).
The SVS lamp should always be illminated and steady
with ignition “ON” and the engine stopped. Ignition feed
voltage is supplied directly to the SVS lamp indicator. The
powertrain control module (PCM) turns the SVS lamp
“ON” by grounding the SVS lamp driver circuit.
The RPL should not remain “ON” with the engine running
and no DTC(s) set. A steady SVS lamp with the engine
running and no DTC(s) suggests a short to ground in the
SVS lamp driver circuit.

Diagnostic Aids

An intermittent may be caused by a poor connection,
rubbed-through wire insulation, or a wire broken inside
the insulation. Check for the following items:

D

Poor connection or damaged harness – Inspect the
PCM harness and connectors for improper mating,
broken locks, improperly formed or damaged
terminals, poor terminal-to-wire connection, and
damaged harness.

Test Description

Number(s) below refer to the step number(s) on the
Diagnostic Chart.
2. If the SVS lamp does not remain “ON” when the

PCM is disconnected, the SVS lamp driver wiring is
not faulty.

3. If the SVS lamp driver circuit is OK, the instrument

panel cluster is faulty.

6. This vehicle is equipped with a PCM which utilizes

an electrically erasable programmable read only
memory (EEPROM). When the PCM is replaced,
the new PCM must be programmed. Refer to

PCM

Replacement and Programming Procedures in
Powertrain Control Module (PCM) and Sensors.
