Dtc P0500: Vss Malfunction - Suzuki Grand Vitara 2011 Manual

1A-323 Engine General Information and Diagnosis: For Diesel Engine Model
Troubleshooting for CC1: Short circuit to +12 V and D1: Micro-breaks
CAUTION
!
EGR valve data initialization procedure is required when the EGR valve is replaced.
The "EGR valve initial offset" and "EGR valve last offset" parameters must be reinitialised.
Refer to "EGR Valve Data Initialization: For Diesel Engine Model in Section 1C" to carry out this
programming.
Check the EGR valve connections.
Check the ECM connections.
Repair if necessary.
Measure the resistance of the EGR valve position feedback potentiometer between "C10-1"and "C10-2"
terminals.
If the resistance displayed is not approximately 5.9 – 7.1 kΩ at 20 °C, 68 °F, replace the EGR valve.
Check for continuity and insulation from +12 V on the following connections:
• Between "C10-3" wire of EGR valve connector and "C86-20" terminal of ECM connector
• Between "C10-2" wire of EGR valve connector and "C85-15" terminal of ECM connector
• Between "C10-1" wire of EGR valve connector and "C86-43" terminal of ECM connector
Repair if necessary.
Ensure the presence of +5 V on "C10-1"terminal of the EGR valve.
Check the operation of the EGR valve:
Perform "Initialize EGR valve data" on SUZUKI scan tool to reinitialise the operating values of the valve and
launch a programming procedure for the EGR offsets (Refer to "EGR Valve Data Initialization: For Diesel Engine
Model in Section 1C").
If the valve is jammed or irrevocably seized, replace the EGR valve.

DTC P0500: VSS Malfunction

NOTE
• Conditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test.
• Use service wire for all operations on the ECM connectors.

Troubleshooting
Check the ABS or ESP® control module connections.
Check the ECM connections.
Repair if necessary.
Check ABS control module assembly or ESP® control module assembly for DTC referring to "DTC Check in
Section 4E" or "DTC Check in Section 4F".
Repair if necessary.
If the fault is still present, substitute a known-good ECM and recheck.
Detecting condition
Inconsistency of signal
Signal outside upper limit
Configuration absent or incorrect
CAN connection fault
