Suzuki XL7 2007 Service Manual page 917

Conditions for Running the DTC
• The vehicle speed is above 8 km/h (5 mph).
• The system voltage is between 9.5-18 volts.
Conditions for Setting the DTC
• The ECM detects an out of range PWM signal during
the KEY ON test.
• The ECM detects a PWM signal greater than 65
percent for at least 5 seconds
• The ECM detects a PWM signal less than 5 percent
for at least 15 seconds during the RUN test.
Action Taken When the DTC Sets
• The ECM will command the charge indicator and or
warning message to be illuminated on the instrument
panel cluster (IPC) and the driver information center
(DIC), if equipped.
• The ECM will not illuminate the malfunction indicator
lamp (MIL).
• The ECM will store conditions, which were present
when the DTC set as Failure Records data only.
Conditions for Clearing the DTC
• The ECM will command the message OFF after one
trip in which the diagnostic test has been run and
passed.
• The history DTC will clear after 40 consecutive warm-
up cycles have occurred without a malfunction.

Circuit/System Verification
Engine running, observe the scan tool ECM GEN-F
Terminal Signal parameter. The parameter should read
between 5-95 percent.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at
the generator.
2. Ignition ON, engine OFF, connect a test lamp to
battery positive voltage and repeatedly probe the
generator field duty cycle circuit, harness side while
monitoring the GEN-F Terminal Signal Parameter in
the ECM data list. It should change from 0 percent to
above 95 percent.
➢ If the parameter was not affected by the test lamp,
test the signal circuit for a short to voltage, short to
ground or an open/high resistance. If the circuit
tests normal, replace the ECM.
3. If the circuit tests normal during the Ignition ON /
RUN tests, and the ECM parameter changed from 0
percent to above 95 percent, replace the generator.
