9WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
NOTE: The conditions that set the DTC are not present at this time. The
following list may help in identifying the intermittent condition.
With the engine running at normal operating temperature, monitor the DRB
parameters related to the DTC while wiggling the wiring harness. Look for param-
eter values to change and/or a DTC to set.
Review the DRB Freeze Frame information. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.

7 Turn the ignition off.
At the Cooler In port, installa0to2070 KPa (300 PSI) gauge using a T.
Ensure the gauge hose is long enough to reach in the driver's side of the vehicle so the
gauge can be monitor while driving.
Road test the vehicle.
Transmission in the Driver gear.
Monitoring the DRB, achieve 80 km/h (50 mph).
NOTE: The gauge will read around 103 KPa (15 PSI) until lockup is achieved
in 3rd gear. If the TCC Solenoid operation is correct, the gauge pressure will
jump when the lockup is achieved.
