Accessing Diagnostic Trouble Codes
1992
Diagnostic trouble codes can be accessed by connecting a TECH 1 or equivalent scan tool or by manually grounding the Assembly Line Diagnostic Link (ALDL) connector. To manually ground the ALDL connector, connect a jumper wire between terminals A and H, Fig. , and observe the flashes of the brake warning lamp. Note the following when performing the Diagnostic Circuit Check to access diagnostic trouble codes:
- When terminals are jumped, count number of short flashes starting from initial long flash, include long flash in count.
- The count se...

Except S & T Series w/VCM & VCM-A
This braking system, Figs. through , is designed to reduce the occurrence of wheel lock-up during severe braking conditions. To accomplish this function, the system regulates hydraulic brake line pressure by using an Electro-Hydraulic Control Unit (EHCU) module or a Brake Pressure Modulator Valve (BPMV). The EHCU/BPMV module has two types of valves: isolation valves, which maintain separate pressure for each front wheel and combine pressure for the rear wheels, and dump valves, which "dump" pressure to each front wheel separately and rear wheels comb...

The Rear Wheel Anti-Lock (RWAL) system, Fig. , reduces the occurrence of rear wheel lockup during severe braking by regulating rear hydraulic line pressure. Pressure applied to the rear wheel brakes is regulated by a control valve assembly located under the master cylinder. The control valve consists of a dump valve which releases hydraulic pressure into an accumulator, and an isolation valve which holds rear brake pressure. Operation of the dump valve and isolation valve is controlled by an Electronic Control Unit (ECU) which is mounted next to the master cylinder.
The ECU rec...

System Operation
This braking system, Fig. , is designed to reduce the occurrence of wheel lock-up during severe braking conditions. To accomplish this function, the system regulates hydraulic brake line pressure when a microprocessor, located inside the Electronic Brake Control Module (EBCM), determines one or more of the wheels is about to lose traction during braking. The EBCM will allow the hydraulic modulator to change brake pressures several times each second to provide maximum vehicle control. This system cannot increase brake pressure above the master cylinder pressure appl...
