16.
Position the new left front exhaust assembly to the exhaust manifold and tighten the flange nuts to 106 in. lbs. (12 N.m).
17.
Position the new right front exhaust assembly to the exhaust manifold and tighten the ball flange nuts to 106 in. lbs. (12 N.m).
18.
Connect the right and left exhaust catalyst assemblies to the "Y" collector pipe (Figure 2).
19.
Install the exhaust system rubber isolator onto the hangers.
20.
Install the front and rear resonator isolator hanger bolts. Tighten the bolts to 215 in. lbs. (25 N.m).
21.
Align the exhaust system so that the clearance between:
a.
Exhaust system and the fuel tank is a minimum of 5/8 in. (16 mm).
b.
Exhaust pipe and the tunnel reinforcement brace clearance is between 5/8" to 3/4" (16 mm to 20 mm).
22.
Tighten the two band clamps at the "Y" collector pipe to 36 ft. lbs. (50 N.m).
23.
Tighten the nuts to both the right and left front exhaust assembly ball flange joints to 25 ft. lbs. (34 N.m).
24.
Install the right front exhaust pipe heat shield nuts at the exhaust manifold ball flange. Tighten the bolts to 98 in. lbs. (10 N.m).
25.
Install the front exhaust pipe brace (if so equipped). Tighten the two bolts to 40 ft. lbs. (55 N.m).
26.
Install both left and right downstream oxygen sensors and tighten to 30 ft. lbs. (40 N.m).
27.
Connect the right electrical harness connector from the right downstream oxygen sensor.
28.
Attach the right downstream oxygen sensor connector to the transmission support crossmember.
29.
Connect the left electrical harness connector to the left downstream oxygen sensor.
30.
Lower the vehicle. Continue to Section B Reprogram the PCM.
B. Reprogram the Powertrain Control Module
NOTE:
This procedure must be performed with release 7.03 or later. A CD containing software release 7.03 was sent to each dealer at the end of January,
2007. If the reprogramming flash for the PCM is aborted or interrupted, repeat the procedure.
1.
Open the hood. Install a battery charger and verify that the charging rate provides 13.0 to 13.5 volts. Do not allow the charger to time out during
the flash process. Set the battery charger timer (if so equipped) to continuous charge.
NOTE:
Use an accurate stand alone voltmeter. The battery charger volt meter may not be sufficiently accurate. Voltages outside of the specified range will
cause an unsuccessful flash. If voltage reading is too high, apply an electrical load by activating the headlamps and/or HVAC blower motor to lower
the voltage.
2.
Connect the CH9410 StarSCAN ethernet cable to the StarSCAN and the dealer's network drop.
3.
Connect the CH9404 StarSCAN vehicle cable to the StarSCAN and the vehicle.
4.
Place the Ignition in the "RUN" position, then Power "ON" the StarSCAN.
5.
Retrieve the old PCM part number. With the StarSCAN on the "Home" screen, follow the procedure below:
a.
Select "ECU View"
