Where is location the automatic transmission shift lock relay in my s10 1998 2.2 2wd


Automatic Transmission Shift Lock Control Description
The brake transmission shift interlock (BTSI) system prevents the automatic transmission from being shifted out of PARK unless the brake pedal is depressed. When the brake pedal is depressed, the BTSI solenoid releases a lock pawl. This enables the shift linkage to move and the shift lever to operate.
When service operations are required, the BTSI system can be overridden.
On vehicles equipped with a column-mounted shift lever, override the BTSI system by performing the following steps:
  1. Turn the ignition switch to the OFF position.
  2. Remove battery voltage from the solenoid.
  3. Turn the ignition switch to the ON position.
For vehicles equipped with floor-mounted shift levers, an override lever is mounted on the right side of the assembly. The override lever can be accessed by removing the shift lever boot. Push the lever to the left in order to override the BTSI.
Which does your S-10 have column or floor shift ? No relay ,has a solenoid .
With Column Shift A/T
The brake transmission shift interlock (BTSI) system prevents the automatic transmission from being shifted out of the PARK position unless the following conditions are present:
?€¢
The brake pedal is depressed.


?€¢
The ignition switch is turned to the RUN or the START position.

When the ignition switch is in the RUN or the START position, the current flows from the B/U Lamp fuse located in the underhood bussed electrical center (UBEC) through CKT 839 (PNK) to the park/neutral position switch. The park/neutral position switch also feeds the backup lamps portion of the switch. With the transmission in the PARK position, the current flows to the BTSI fuse located in the underhood bussed electrical center (UBEC) through CKT 275 (LT GRN). The current then flows to the TCC/stoplamp switch through CKT 584 (LT GRN/BLK). The current continues to the BTSI solenoid through CKT 1135 (DK GRN/WHT). The ground path is provided through CKT 1850 (BLK) to G207. When the brake pedal is depressed, the normally closed contacts in the TCC/stoplamp switch open and the current flow is interrupted. When the current flow is interrupted, the BTSI solenoid de-energizes. The transmission may then shift to another gear. When the transmission shifts to another gear (except PARK), the contacts in the park/neutral position switch open. This condition stops the current flow to energize the solenoid when the brake pedal releases.

Why wont my car shifter shift out of park?


Does the engine start ? Is this a automatic transmission vehicle ? Do the brake lights work when you press on the brake pedal ? It probably has something to do with the Automatic Transmission Shift Lock
The brake transaxle shift interlock (BTSI) system consists of the body control module (BCM), powertrain control module (PCM), BTSI solenoid, stop lamp switch, and PRNDL selector switch. The BTSI system prevents the driver from moving the shift lever out of PARK unless the brake pedal is depressed while in RUN or CRANK.
The BCM controls the output to the BTSI solenoid by grounding the solenoid which energizes it, preventing shifting out of PARK. When the BCM receives input from the PCM over the Class II link that the transaxle is in PARK and the brake pedal is depressed, it will stop grounding the BTSI solenoid or de-energize it which will allow shifting. After the transaxle is moved out of the PARK position, the BCM shall monitor the status of the PRNDL serial data message sent by the PCM and shall continue to de-energize the solenoid until the transaxle has been returned to the PARK position.
In the event that the serial data messages are never received (approximately 5 seconds) by the BCM from the PCM, the BCM shall de-energize the solenoid to allow shifting. The transaxle can be shifted from PARK by placing the ignition switch in the ACC position. This eliminates power to the solenoid.

Need to locate ebcm for a 1996 tahoe


The ebcm has nothing to do with the brake lights , the ebcm - electronic brake control module is for the ABS - anti-lock brake system !
Stoplamps
Voltage is available at all times through the STOP/HAZ fuse to the torque converter clutch (TCC)/stoplamp switch. With the depression of the brake pedal, the contacts in the TCC/stoplamp switch close. Voltage is available from the stoplamp relay on pickups, or the TCC/stoplamp switch on all of the other vehicles, through the turn/hazard switch to the left stoplamp, the right stoplamp, and the stoplamp lights. If a turn signal is in operation, the stoplamp on that side flashes as a turn signal. The other stoplamp serves as a stop lamp.

1998 buick regal LS 3.8 engine dies wont turn over and stuck in park.


Well , first off being stuck in gear, there probably is a problem with
The park lock solenoid prevents shifting out of the PARK position when the ignition switch is in LOCK, ACC, or OFF. The Brake Transmission Shift Interlock (BTSI) is designed to prevent shifting out of PARK when the ignition switch is in the RUN, BULB TEST, or START position, without pressing the brake pedal. The BTSI solenoid and the park lock solenoid are energized when the ignition switch is in the RUN, BULB TEST, or START position. When the park lock solenoid and the Brake Transmission Shift Interlock (BTSI) are energized, the mechanical lock connected to this park lock solenoid is pulled away from the shifter. The stop lamp switch receives ignition voltage in the RUN, BULB TEST, or START position from the BTSI Fuse and is normally closed, providing voltage through circuit 1135 to the BTSI solenoid, energizing the solenoid and mechanically locking the transmission shift lever whenever it is in PARK. When the brake pedal is pressed, the stop lamp switch opens, removing voltage from circuit 1135 to the BTSI solenoid. The BTSI solenoid is de-energized and the mechanical lock connected to the BTSI solenoid pulls back from the shifter allowing shifting.

You would do well to buy a service repair manual subscription from ALLDATA OEM Auto Repair Information for Professionals you have no idea of the complexity of the electronics on your vehicle . You will need wiring diagrams to sort out your electrical issues , suggest you watch videos on youtube for voltage drop testing . if your dad doesn't know electrical testing .

Which fuse box do i check for fuse for cruise control


There is actuly 2 differant fuse #12 the brake fuse #12 10 amp and fuse #1 the stop and haz 20 amp .But neighter are likely the problem . There is another brake switch for the cruise control called the TCC brake and cruise control relese switch that tells the transmission when the brake is applyed and shut of the cruise control . This is more likely the problem its up under the dask near the steering colluom follow the wires from the main brake switch on the pedel if you have a standard then it will run through the clutch switch as well .Fuse #12 also controls the muilty function switch but fuse #1 is the brake input switch . So if the lights and blinkers work i would look at the TCC brake switch first thank you

My 2004 venture will not shift it says check the fuses rock the van I cannot find a fuse on the panel for the transmission and rocking it does not work and the BTSI solenoid I have no idea where that is


Fuse panels can be located sround the pedal or steering column area or underneath your glove box and the BTSI solenoid should be inside the steering column.

I own a 2005 GMC Canyon Five CYL and the cruise control stopped working last niight. You push the button and no cruise. I checked the fuse and it is ok I exchanged with another 10AMP and no change still...


Start with the simple and check the fuses and the Stop lamp switch. Check your brake lights, if they're not working, the cruise won't work either. If they're not working, check the fuse for them, if the fuse is fine, then take it into the dealer, there's been a recall issued on the brake switch, so it should get fixed for free.
Cruise Control Disengaged
The powertrain control module (PCM) disengages the cruise control operation based on the signals from the following switches:

* The stop lamp switch
* The TCC brake/cruise release switch
* The clutch release switch, if equipped
* The cruise control On/Off switch

The TCC brake/cruise release switch and the stop lamp switch are mounted on the brake pedal bracket. When the brake pedal is applied, the normally closed TCC brake/cruise release switch opens and the normally open stop lamp switch closes. The PCM detects a low signal voltage on the TCC brake/cruise release switch signal circuit and a high signal voltage on the stop lamp switch signal circuit. When the clutch pedal is applied, the normally closed clutch release switch opens and the PCM detects zero voltage on the CCP switch signal circuit. The vehicle speed stored in the memory of the PCM will be erased when the cruise control On/Off button is turned OFF, or the ignition switch is turned OFF.

The Cruise Control System will disengage when the PCM detects that a driver override function has been active for approximately 60 seconds .

When the Cruise Control System is disengaged, the PCM sends a class 2 message to the instrument panel cluster (IPC) in order to deactivate the cruise control indicator.

Cruise Control Inhibited
The powertrain control module (PCM) inhibits the cruise control operation when any of the following conditions exist:

* A cruise control related DTC has been set.
* The vehicle speed is less than 40.2 km/h (25 mph) .
* The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
* The engine RPM is too low.
* The engine RPM is too high, with fuel cut off.
* The vehicle speed is too high, with fuel cut off.
* The system voltage is not between 9 volts and 16 volts .
* The Traction Control System (TCS) is active for more than 2 seconds .

Thank you for using Fixya and start with replacing the stop lamp switch. Even though the brake light work, it;s been known for that switch to cause your issue. that's way there was a recall for it.
