2. Test for less than 1 ohm between the ground circuits listed below and ground.
* Terminal 13
* Terminal 38
瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.
3. Ignition ON, verify that a test lamp illuminates between the B+ circuits listed below and ground.
* Terminal 1
* Terminal 25
瀚慖f the test lamp does not illuminate, test the appropriate circuit for a short to ground or an open/high resistance. If the circuit tests normal
and the B+ circuit fuse is open, replace the brake pressure modulator valve assembly.
4. If all circuits test normal, replace the EBCM and verify DTC does not reset. If the DTC resets, replace the brake pressure modulator valve
assembly.
