Tech 2 Miscellaneous Tests

Description

1-2 Solenoid

•	The TCM commands the 1-2 shift solenoid valve on and off. Tech 2's Shift Solenoid A Parameter should match the commanded state. Tech 2's Commanded Gear parameter should correspond with the shift solenoid combination. Refer to Shift Solenoid Valve State and Gear Ratio.

•	When the ignition is on, and the engine is off, there no limits to this control. The solenoid remains on until commanded off, and vice versa. When the test is exited, the solenoid state is determined by the TCM.

•	When the engine is running, the following control limits apply:

-	Only sequential gear changes are allowed. For example, 1st to 3rd is not allowed. If a non-sequential gear change is attempted, the message Non-sequential gear changes not allowed. Gear changes must be made in order appears on Tech 2.

-	The vehicle speed must be below a calibrated value. If the vehicle speed is too high, the message Vehicle speed too high appears on Tech 2.

-	The engine speed must be below a calibrated value. If the engine speed is too high, the message Engine speed too high appears on Tech 2.

-	Downshifts are allowed only when the vehicle speed is below a calibrated value. If the vehicle speed is too high, the message Eng. is on and veh. speed too hi for 3-2 or 2-1 downshift appears on Tech 2.

The gear requested may not be greater than the current selected transmission range (PRNDL). For example, 3rd gear is not allowed if the transmission range is D2. If the gear requested is greater than the current selected transmission range, the message Eng. running and gear request is greater than the current TR appears on Tech 2.

•	The solenoid remains on until commanded off, and vice versa. When the test is exited, the solenoid state is determined by the TCM.

2-3 Solenoid

•	The TCM commands the 2-3 shift solenoid value on and off. Tech 2's Shift Solenoid B parameter should match the commanded state. Tech 2's Commanded Gear parameter should correspond with the shift solenoid combination. Refer to Shift Solenoid Valve State and Gear Ratio

•	When the ignition is on, and the engine is off, there no limits to this control. The solenoid remains on until commanded off, and vice versa. When the test is exited, the solenoid state is determined by the TCM.

•	When the engine is running, the following control limits apply:

-	Only sequential gear changes are allowed. For example 1st to 3rd is not allowed. If a non-sequential gear change is attempted, the message Non-sequential gear changes not allowed. Gear changes must be made in order appears on Tech 2.

-	The vehicle speed must be below a calibrated value. If the vehicle speed is too high, the message Vehicle speed too high appears on Tech 2.

-	Downshifts are allowed only when the vehicle speed is below a calibrated value. If the vehicle speed is too high, the message Eng. is on and veh. speed too hi for 3-2 or 2-1 downshift appears on Tech 2.

The gear requested may not be greater than the current selected transmission range (PRNDL). For example, third gear is not allowed if the transmission range is D2. If the gear requested is greater than the current selected transmission range, the message Eng. running and gear request is greater than the current TR appears on Tech 2,

-	The Solenoid remains on until commended off, and vice versa. When the test is exited, the solenoid state is determined by the TCM.

3-2 Downshift Solenoid

•	The TCM commands the 3-2 shift solenoid valve on and off. Tech 2's 3-2 Downshift Sol. parameter should match the commanded state.

•	When the ignition is on, and the engine is off, there are no limits to this control. The solenoid remains on until commanded off, and vice versa. When the test is exited, the solenoid state is determined by the TCM.

•	When the engine is running, the following control limits apply:

-	The transmission range (PRNDL) must be Park or Neutral. Is the transmission range is not in Park or Neutral, the message Engine running and transmission range is not Park/Neutral appears on Tech 2.

-	The solenoid remains on until commanded off, and vice versa. When the test is exited, the solenoid state is determined by the TCM.

Clear TAPS (Transmission Adaptive Pressures)

•	The TCM clears (or resets) the TAP cells to the original base value.

•	There are no limits to using this test. It may be performed with the engine running or when the ignition is on, and the engine is off.

PC Solenoid

•

The TCM commands the current to the pressure control solenoid in order to control transmission line pressure. As the current increase, the line pressure decreases. As the current decreases, the line pressure increases, The current range is 0.00 - 1.10 A and may be commanded in one-tenth of an amp increments.

•	When the ignition is on, and the engine is off, the reference (commanded) amperage may be controlled within calibrated limits. Tech 2's parameter PCS Desired Current changes by the parameter PCS Actual Current does not change. The reference current remains until commanded otherwise.

•	When the engine is running, the following control limits apply:

When the transmission range is Park or Neutral, the reference (commanded) current may be controlled within calibrated limits. The engine speed must be less than 1,500 RPM. If the engine speed is greater than 1,500 RPM the message TR in park/neutral and engine speed over 1,500 RPM appears on Tech 2. Both Tech 2 parameters PCS Desired Current and PCS Actual Current parameters change. Both current readings remain until commanded otherwise.

When the transmission range is not in Park or Neutral, the reference current can only be controlled less than the current determined by the TCM. The TCM does not allow a value to be selected that may cause damage to the transmission. If the requested amperage is more than allowed by the TCM, the message Requested current for the PC Solenoid is too high appears on the Tech 2.

•	Transmission range DTCs must not be active. If a transmission range DTC is active, the message Engine running with transmission DTC present appears on Tech 2.

Shift Transmission

•	The TCM commands upshifts and downshift. Tech 2 Commanded Gear parameter should correspond with the shift solenoid combination. Refer to Shift Solenoid Valve State and Gear Ratio.

•	When the ignition is on, and the engine is off, there are no limits to this control. The Tech 2 shift solenoid states changes to match the Commanded Gear selected.

•	When the engine is running, the following control limits apply:

-	The TCM does not allow a shift if it causes the engine r.p.m. to exceed a calibrated limit. If a gear is requested and the engine speed is too high, the message Engine speed too high appears on Tech 2.

-	The TCM does not allow a 3-2 or 2-1 downshift if the vehicle speed exceeds a calibrated limit. If either downshift is requested and the vehicle speed is too high, the message Eng. is on and veh. Speed too hi for 3-2 or 2-1 downshift appears on Tech 2.

-	The TCM does not allow a 4-3 downshift if this vehicle speed exceeds a calibrated limit. If a 4-3 downshift is requested and the vehicle speed is too high, the message Vehicle speed to high appears on Tech 2.

-	The TCM does not allow an upshift if the vehicle speed exceeds a calibrated limit. If an upshift is requested and the vehicle speed is too high, the message Vehicle speed to high appears on Tech 2.

The TCM does not allow an upshift that is greater than the current selected transmission range (PRNDL). For example 3rd gear is not allowed if the transmission range is D2. If an upshift is requested that is greater than the current selected transmission range, the message Eng. running and gear request is greater than the current TR appears on Tech 2.

TCC Control Solenoid

•

The TCM commands the duty cycle of the TCC PWM solenoid. The duty cycle is represented by a percentage of on (energised) time. Approximately 90-100 percent duty cycle represents an on (energised) commanded state. Zero percent represents an off (non-energised) commanded state. Tech 2 TCC PWM Solenoid parameter should match the commanded state.

•	When the ignition is on, and the engine is off, there are no limits to this control. The solenoid remains on (90-100 percent duty cycle) until commanded off (zero percent duty cycle), and vice versa. When the test is exited, the solenoid duty cycle is determined by the TCM.

•	When the engine is running, the following control limits apply:

-	If the transmission range is Park, and the transmission is in hot mode, the TCC control solenoid may not be commanded off. If the solenoid is requested off, the message TCC OFF commanded disabled in Hot Mode appears on Tech 2.

-	The TCC control solenoid may not be commanded off for more than a calibrated amount of time. If the solenoid is commanded off for a certain amount of time, the message TCC OFF time has been exceeded appears on Tech 2.

TCC Enable

•	The TCM commands the TCC enable solenoid valve on and off. Tech 2's TCC Solenoid parameter should match the commended state.

•	When the ignition is on, and the engine is off, there are no limits to this control. The solenoid remains on until commanded off, and vice versa. When the test is exited, the solenoid state is determined by the TCM.

•	When the engine is running, the following control limit apply:

-	If the transmission range is Park or Neutral, the TCC enable solenoid may not be commanded off for more than a calibrated amount of time. If the solenoid is commanded off for a certain amount of time, the message TCC OFF time has been exceeded appears on Tech 2.

If the transmission range is Park or Neutral and the TCC control colonnade duty cycle is less than maximum capacity, the TCC solenoid may not be commanded on. If the solenoid is requested on during these conditions, the message TCC Control Solenoid is not set to maximum Pressure appears on Tech 2.

-	If the TCC control solenoid duty cycle is less than maximum capacity, the TCC solenoid may not be commanded on. IF the solenoid is commanded on during these conditions the message TCC Control Solenoid is not set to maximum Pressure appears on Tech 2.

-	If the transmission is not hot mode, the TCC solenoid may not be commanded off. If the solenoid is requested off the message TCC OFF commanded disabled in Hot Mode appears on the scan tool display.
