Installthe battery. Clean the battery posts and
cable terminals with sandpaper, then assemble
them and apply grease to prevent corrosion.
Check that the transmission shifts into gear
smoothly.
Inspect for fuel leaks. Turn the ignition switch ON(ll) {do not operate the starter) so that the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation two or three times, then
check for fuel leakage at any point in the fuel line.
Refillthe engine with engine oil (see page 8-5).
Refill the transmission with fluid (see page 13-3).
Refill the radiator with engine coolant, and bleed
air from the cooling system with the heater valve
open (see page 10-6).
Perform the engine control module (ECM) idle learnprocedure (see page 11-139).
Inspect the idle speed (see page 1 1-138).
Inspect the ignition timing (see page 4-17).
Check the wheel alignment {see page 18-4).
Enter the anti-theft code for the radio, then enter
the customer's radio station presets.

DTC Troubleshooting (cont'dl
DTC P0500: VSS Circuit Malfunction
1. Test-drive the vehicle.
2. Check the vehicle speed with the scan tool.
ls the correct speed indicated?
YES-lntermiftent failure, system is OK at this time.
Check for poor connections or loose terminals at
the VSS and at the ECM.I
NO Go to step 3.
3. Turn the ignition switch OFF.
4. Block the rear wheels, and set the parking brake.
5. Raise the front ofthe vehicle, and make sure it is
securely supported,
Turn the ignition switch ON (ll).
Block the right front wheel, and slowly rotate the
left front wheel.
8. Measure voltage between ECM connector
terminals A18 and A24.
ECM CONNECTOR A {31P)
Wire side of female terminals
Does the voltage pulse between 0 V and 5 V or
between 0V and battery voltage?
YES-Update the ECM if it does not have the latest
software, or substitute a known-good ECM. then
recheck (see page 1 1-6). lf the symptom/indication
goes away with a known-good ECM, replace the
original ECN4.l
NO Go to step 9.

goes away with a known-good ECM, replace the
origlnal ECM.I
NO Check these items:
. A short or an open in the wire between the ECM
(A18) and the VSS.I. lf thewire is OK,testtheVSS (see page 22 71).1
