PROCEDURE

1. CHECK BRAKE BOOSTER ASSEMBLY




(a) Disconnect the A18 booster connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPLACE BRAKE BOOSTER ASSEMBLY
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - ACTIVE BRAKE BOOSTER)




(a) Confirm that the skid control ECU connector and active brake booster connector are properly connected.
(b) Disconnect the A17 ECU connector.
(c) Disconnect the A18 booster connector.
(d) Inspect both the connector case and the terminal for deformation and corrosion.
OK:
No deformation or corrosion.
(e) Measure the resistance according to the value(s) in the table below.
