20 Most Recent 2003 Cadillac Escalade Questions & Answers


If you honestly ask me, there is no bypass.It would remain on if you go for non auto shocks.

The only way is to go with auto levelling shocks, might be japanese made which might cost you around $350 per piece.


Thanks.

You need to have the front end checked out at an alignment shop. Possible causes are worn tire rod ends or control arm bushings, failing drive axle CV joint, loose stabilizer bar, etc.

Having a qualified repair shop check it out would be your best bet . These light;s being on means DTC'S - dignostic trouble codes are stored .
SERVICE STABILITY SYSTEM
Refer to ABS Description and Operation in Antilock Brake Systems Vehicles with RPO JL4 are equipped with an EBC 430EV ABS/DRP/TCS/VSES module.
This module provides the following vehicle performance enhancement systems.
• Antilock Brake System (ABS)
• Dynamic Rear Proportioning (DRP)
• Traction Control System (TCS)
• Vehicle Stability Enhancement System (VSES)
The following components are involved in the operation of the above systems.
• Electronic brake control module (EBCM) - The EBCM controls the system functions and detects failures.
The EBCM contains the following components.
- System relay - The system relay is internal to the EBCM. The system relay is energized when the ignition is ON. The system relay supplies battery positive voltage to the valve solenoids and to the ABS pump motor. This voltage is referred to as system voltage.
- Solenoids - The solenoids are commanded ON and OFF by the EBCM to operate the appropriate valves in the brake pressure modulator valve (BPMV).
- Longitudinal Accelerometer - The EBCM uses the longitudinal accelerometer to determine the actual straight-line acceleration of the vehicle.
• Brake pressure modulator valve (BPMV) - The BPMV uses a 4-circuit configuration to control hydraulic pressure to each wheel independently.
The BPMV contains the following components.
- ABS pump motor and pump
- Four isolation valves
- Four dump valves
- Two TC isolation valves
- Two TC supply valves
- A master cylinder pressure sensor
- A front low-pressure accumulator
- A rear low-pressure accumulator
• Wheel speed sensors (WSS) - As the wheels spin, toothed rings interrupt magnetic fields in the wheel speed sensors. This causes each wheel speed sensor to generate an AC signal. The EBCM uses these AC signals to calculate the wheel speed. Any imperfections in the toothed ring, such as a missing or damaged tooth, can cause an inaccurate WSS signal.
• Traction control switch - VSES and the engine torque reduction function of TCS are manually disabled or enabled by pressing the traction control switch.
• Lateral accelerometer - The EBCM uses the lateral accelerometer to determine the sideways acceleration of the vehicle. The lateral accelerometer is packaged with the yaw rate sensor as a single component.
• Master cylinder pressure sensor - The master cylinder pressure sensor is located within the BPMV. The master cylinder pressure sensor uses a 5-volt reference and generates an output signal proportionate to the hydraulic fluid pressure which is present in the front brake circuit at the master cylinder.
• Yaw rate sensor - The EBCM uses the yaw rate sensor to determine the rate of rotation along the vehicle's vertical axis. The yaw rate sensor is packaged with the lateral accelerometer as a single component.
• Steering wheel position sensor - The electronic brake control module (EBCM) receives several inputs from the steering wheel position sensor. 3 digital square wave signal inputs are wired directly to the EBCM harness connector, however, only signals A and B are used or monitored. The failure of the index pulse signal does not effect VSES function. The body control module (BCM), which receives an analog steering position sensor input, transmits steering position data on the serial data line. The EBCM monitors the serial data information as an added failsafe for the steering position sensor circuitry. Battery voltage is supplied to the digital portion of the steering wheel position sensor from the cruise control fuse. The analog portion of the steering wheel position sensor is supplied a 5-volt reference from the BCM. This circuit is also used for a lamp dimming function.
• Precharge pump motor and pump - The precharge pump assembly is used to assist the ABS pump in rapidly building hydraulic pressure needed during certain TCS or VSES events

Automatic transmission rebuilding on newer cars is an astronomical undertaking. Tons of special tools. One minor mistake and you have to do it all over again.
Buy a GM reman that's been tested on a stand and has a 3yr/50,000 mile warranty that is honored nationwide at any GM dealer.
Just keep your paperwork.

Hello Francisco...

There are several different elements to your anti-theft
system...

Other than lost or damaged keys
the "coil" in your steering column would be a great place to
look for trouble... I am going to pull up a part to show you the ease... (eBay & AMAZON work equally well)...

you can not have less than zero oil pressure so the indications are that there is a fault with the oil pressure sender or oil pressure sensor
you should take the car to an accredited service center and have the oil pressure tested using a mechanical gauge to prove what oil pressure you have
from there you have the faulty item replaced

Does your Escalade have memory seats ?
There are 2 options of power seat systems available in full size trucks. The 6 way driver and passenger power seats, and 8 way driver and passenger power seats with driver memory. For the driver memory seat operation refer to Memory Seats Description and Operation . Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.
