Cruise Control Unit Input Test
SRS components are located in this area. Reviewthe SRS component locations (see page 23-'13) and precautions andprocedures (see page 23-14) in the SRS section before performing repairs or service.
1. Disconnect the 14P connector from the control unit.
2. Inspect the connector and socket terminals to be sure they are all making good contact.
. lf the terminals are bent, loose, orcorroded, repairthem as necessary, and recheckthe system.. lf the terminals look OK, go to step 3.

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).
