Anti-Lock Brake System - BOSCH 2U: Diagnosis: Notes

NOTE: To diagnose ABS system, manufacturer recommends using Tech 1 Scan Tester (94-00101-A) with 1988-94 Brake Cartridge, and Bosch ABS DLC adapter. Some diagnostic procedures will require EBCM Pinout Box (J-35592) and High-Impedance Digital Multimeter (J-39200) or equivalent. When using Tech 1 for diagnostics, ABS system is disabled by EBCM. ANTILOCK indicator will come on indicating only normal power assisted braking is available. After diagnostics have been completed using Tech 1, disconnect Tech 1 from DLC connector and turn ignition off for a least 10 seconds before road testing. This procedure is done to reset EBCM.
