Circuit Inspection - Suzuki Liana RH413 Service Manual

1C-7 Engine Electrical Devices:
3) Connect connector to it securely.
4) Adjust generator drive belt tension referring to
"Water Pump / Generator Drive Belt Tension
Inspection and Adjustment in Section 1F".
5) Connect negative cable to battery.
Crankshaft Position (CKP) Sensor and Its

Circuit Inspection

1) Confirm that terminal voltages and ground circuit
continuity at CKP sensor connector terminals are in
good condition referring to Step 3 and 5 of "DTC
P0335 (No. 23): Crankshaft Position (CKP) Sensor
Circuit Malfunction in Section 1A".
If not, repair CKP sensor circuit.
If circuits are in good condition, check ECM referring
to "Inspection of ECM and Its Circuits in Section 1A".
2) Check that CKP sensor signal voltage varies from
low to high or from high to low as specified referring
to Step 6 of "DTC P0335 (No. 23): Crankshaft
Position (CKP) Sensor Circuit Malfunction in Section
1A".
If signal voltage varies as specified, CKP sensor is in
good condition.
If not, replace CKP sensor.
Vehicle Speed Sensor (VSS) and Its Circuit
Inspection
1) For A/T vehicle, referring to "Output Shaft Speed
Sensor / VSS Inspection in Section 5A".
2) For M/T vehicle, confirm that terminal voltages at
VSS connector terminals are in good condition
referring to Step 6 and 7 of "DTC P0500 (No. 16):
Vehicle Speed Sensor (VSS) Malfunction in Section
1A".
If not, repair VSS circuit.
If circuits are in good condition, check ECM referring
to "Inspection of ECM and Its Circuits in Section 1A".
3) Check that VSS signal voltage varies from low to
high or from high to low as specified referring to Step
8 of "DTC P0500 (No. 16): Vehicle Speed Sensor
(VSS) Malfunction in Section 1A".
If signal voltage varies as specified, VSS is in good
condition.
If not, replace VSS.
Main Relay, Fuel Pump Relay, A/C Compressor
Relay and A/C Condenser Fan Relay Inspection
1) Disconnect negative cable at battery.
2) Remove main relay (1), fuel pump relay (2), A/C
compressor relay (3) and A/C condenser fan relay
(4) from vehicle.
3) Check that there is no continuity between terminal
"C" and "D". If there is continuity, replace relay.
S3RH0A1306021
4) Connect battery positive (+) terminal to terminal "B"
or relay. Connect battery negative (–) terminal "A" of
relay. Check continuity between terminal "C" and "D".
If there is no continuity when relay is connected to
the battery, replace relay.
