ENGINE CONTROL SYSTEM (4JK1/4JJ1) 6E-257
DTC P1664 (Flash Code 76)
Circuit Description
The service vehicle soon (SVS) lamp is located on the
instrument panel (IP) cluster. The SVS lamp informs
the driver that a non-emission related fault has
occurred and vehicle service required.
The ECM monitors the SVS lamp control circuit for
conditions that are incorrect for the commanded state
of the SVS lamp. For example, a failure condition exists
if the ECM detects low voltage when the SVS lamp is
commanded OFF, or high voltage when the SVS lamp
is commanded ON. If the ECM detects an improper
voltage level on the control circuit, this DTC will set.
Condition for Running the DTC • The ignition voltage is more than 9 volts.
• The ignition switch is ON.
Condition for Setting the DTC
Low Voltage DTC • The ECM detects a low voltage condition on the SVS lamp control circuit when the lamp is
commanded OFF.
High Voltage DTC
• The ECM detects a high voltage condition on the SVS lamp control circuit when the lamp is
commanded ON. Action Taken When the DTC Sets
Low Voltage DTC • The ECM will not illuminate the MIL or SVS lamp.
• Refer to DTC Type Definitions for Action Taken When the DTC Sets - Type D.
High Voltage DTC
• The ECM illuminates the SVS lamp when the diagnostic runs and fails. Refer to DTC Type
Definitions for Action Taken When the DTC Sets -
Type C.
Condition for Clearing the DTC
Low Voltage DTC • Refer to DTC Type Definitions for Condition for Clearing the DTC - Type D.
High Voltage DTC
• Refer to DTC Type Definitions for Condition for Clearing the SVS Lamp/ DTC - Type C.
Diagnostic Aids • If an intermittent condition is suspected, refer to Intermittent Conditions in this section.
