2. No : INFORM the customer that tire size should not exceed OEM recommendations and that all 4 tires should be the same size, brand and tread wear. INSTALL new tire(s) as necessary.
CHECK TIRE AIR PRESSURES
1. Check the air pressure in all 4 tires.
Are all 4 tires at the recommended air pressure?
1. Yes: GO to 4 .
2. No : ADJUST the tire air pressures. INFORM the customer to maintain the correct tire air pressure.
CHECK FOR CORRECT WHEEL SPEEDS
1. Using a scan tool, view ABS PIDs .
2. While driving the vehicle at 48 km/h (30 mph), monitor the ABS module wheel speed sensor PIDs :
  - Left Front Wheel Speed Sensor (LF_WSPD)
  - Left Rear Wheel Speed Sensor (LR_WSPD)
  - Right Front Wheel Speed Sensor (RF_WSPD)
  - Right Rear Wheel Speed Sensor (RR_WSPD)
Are all 4 wheel speeds within 2 km/h (1.2 mph) of each other?
1. Yes: GO to 5 .
2. No : CARRY OUT ABS module self-test. REFER to DTC CHART: ANTI-LOCK BRAKE SYSTEM (ABS) MODULE for diagnosis of all DTCs .
3. CHECK FOR CORRECT PCM OPERATION
  1. Ignition OFF.
  2. Disconnect and inspect all PCM connectors.
  3. Repair:
    - corrosion (install new connector or terminals - clean module pins)
    - damaged or bent pins - install new terminals/pins
    - pushed-out pins - install new pins as necessary
  4. Reconnect the PCM connectors. Make sure they seat and latch correctly.
  5. Operate the system and determine if the concern is still present.
  Is the concern still present?
  1. Yes: CHECK OASIS for any applicable TSBs . If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs address this concern, INSTALL a new PCM. REFER to POWERTRAIN CONTROL MODULE (PCM) - 3.5L TI-VCT
  2. No : The system is operating correctly at this time. The concern may have been caused by module connections. Address the root cause of any connector or pin issues.
