CHECK AT TCL/ASC-ECU

TERMINAL VOLTAGE CHECK CHART

Required Special Tool:

1. Disconnect the TCL/ASC-ECU connector A-32, and then use the special tool ABS Check Harness
(MB991952) to measure the voltages between terminal No.34 and each terminal other than terminal No.12 as well as between terminal No.12 and each terminal other than terminal No.34.
NOTE:
Do not measure terminal voltage for approximately three seconds after the ignition switch is turned "ON." The TCL/ASC-ECU performs the initial check during that period.
