Set Condition:

Set condition:  This code is set whenever Power-train Control Module (PCM) senses an internal error.

Set condition:  This code is set whenever the PCM is disconnected from battery power (B+) or ground. It will also be set during the DRBIII® Battery Disconnect procedure.

Set condition:  This code is set if the PCM senses greater than 3 volts at the Trans Relay Output (switched battery) terminal of the PCM prior to the PCM energizing the relay.

Set condition:  This code is set when less than 3 volts are present at the Trans Relay Output (switched battery) terminals at the PCM when the PCM is energizing the relay.

Set condition:  This code is set when the engine speed sensed by the Transmission Control System is less than 390 RPM or greater than 8000 RPM for more that 2.0 seconds.

Set condition:  If no PCI bus messages are received from the Powertrain Control Module (PCM) for 10 seconds.

Set condition:  This code is set if the PCM senses voltage on any of the pressure switch inputs prior to the PCM energizing the relay.

Set condition:  This code is set if the OD pressure switch is open or closed at the wrong time in a given gear (see chart below).

Set condition:  This code is set if the 2/4 pressure switch is open or closed at the wrong time in a given gear (see chart below).

Set condition:  This code is set if the LR pressure switch is either open or closed at the wrong time in a given gear.

Set condition: 

1. P0124 - Throttle angle change > 5° in 7 milliseconds the Fault set time milliseconds 0.448 seconds
2. P0122 - Throttle angle < 6° the Fault Set Time: 0.448 seconds
3. P0123 - Throttle angle > 120.6° the Fault Set Time: 0.448 seconds

Set condition:  Immediately after a shift into 1st, 2nd, or 3rd gear, with engine speed above 1000 RPM, the PCM momentarily turns on element pressure to the 2/4 and/or OD clutch circuits to identify that the appropriate pressure switch closes. If the pressure switch does not close it is tested again. If the switch does not close the second time, the appropriate code is set.

Set condition:  If the transmission begins to slip in any forward gear, and the pressure switch or switches that should be closed for a given gear are open, a loss of prime test begins. All available elements (in 1st gear LR, 2/4 and OD, in 2nd, 3rd, and 4th gear 2/4 and OD) are turned on by the PCM to see if pump prime exists. The code is set if none of the pressure switches respond. The PCM will continue to run the loss of prime test until pump pressure returns.

Set condition:  This code is set if the associated gear ratio code is stored within 1.3 seconds after a shift.

Set condition:  This code is set if three unsuccessful attempts are made to get into 1st gear in one given key start.

Set condition: 

1. The transmission must be in EMCC, with the input speed greater than 1750 RPM. The TCC/LR solenoid must achieve it's maximum duty cycle and still not be able to pull the engine speed within 60 RPM of input speed.
2. If the transmission is in FEMCC and the engine can slip the TCC by more than 100 RPM (Engine speed - Input speed) for 10 seconds.

The code will be set if one of these event happens three times at a throttle angle less than 30 degrees.

Set condition:  All four solenoids are tested for continuity continuously immediately upon start up and during vehicle operation. For solenoids that are currently energized, power is momentarily interrupted, then reenergized. For solenoids that are not currently energized, the solenoid is momentarily energized, then deenergized. Under both situations, if an inductive spike is not sensed by the PCM during the continuity check, it is retested twice. If it fails the test the third time, the appropriate code is set.

Set condition:  If the transmission senses the LR pressure switch closing while performing PEMCC or FEMCC. This code will be set after two unsuccessful attempts to perform PEMCC or FEMCC.

Set condition:  This code is set if the gear ratio is not correct for a period of time.

• Codes 50 through 54 sets if the ratio of the input RPM (Nt) to the output RPM (No) does not match the given gear ratio.
• Code 56 sets if there is an excessive change in input RPM in any gear
• Code 57 sets if there is an excessive change in output RPM in any gear
• Code 58 sets after a TCM reset in neutral and Nt/No equals a ratio of input to output of 2.50

A hard code sets within 3 seconds, an intermittent code sets within 15 seconds.

Set condition: 

1. The transmission shift lever is not in AutoStick and either the upshift or downshift switch is closed.
2. Upshift and downshift switches closed at the same time.

Set condition: 

1. If the engine temperature exceeds 124 C (255°F) while operating in AutoStick mode.
2. If the transmission temperature exceeds 135°C (275°F) while in AutoStick mode

Set condition:  The code will be set if vehicle shudder is detected 20 times when the A/C clutch is cycled.

Set condition:  Immediately once the Overheat Shift Schedule is activated.

Set condition:  If the PCM powers up while in the "Drive" position and the vehicle is going above 32 Km/h (20 MPH), the code is set.

Set condition:  If no PCI bus messages are received from the Mechanical Instrument Cluster (MIC) for 25 seconds.

Set condition:  If no PCI bus messages are received by the Transmission Control System for 10 seconds.

Set condition:  If the battery voltage of the Transmission Control Relay Output Sense circuit(s) to the PCM is less than 10.0 volts for the period of 15 seconds. The DTC will also set if the direct battery voltage sensed in the PCM is less than 6.5v for 200ms or where Transmission Control Relay Output Sense circuit (switched battery) is less than 7.2v for 200ms. Note: P0562 generally indicates a gradually falling battery voltage or a resistive connection(s) to the PCM.

Set condition:  A temperature reading of 80°F is not reached in the specified period of time

Set condition:  Sensor output voltage less than 0.078v.

Set condition:  Sensor output voltage greater than 4.94v.

Set condition:  Temperature reading change greater than maximum change allowed per loop.
