BR–128 BRAKE SYSTEM – TRACTION CONTROL SYSTEM (TRAC) DIAGNOSTIC TROUBLE CODE CHART If a malfunction code is displayed during the diagnostic trouble code check, check the circuit listed for that code in the table below and proceed to the relevant page. HINT: If the TRAC indicator light lights up and the TRAC indicator light does not blink when the DTC is checked, check the blinking pattern of the ABS warning light and troubleshoot the ABS system. Code | TRAC Indicator Light Blinking Pattern | Diagnosis | See page 24 | BE3932 | Open or short in sub–throttle actuator circuit | BR–134 25 | BE3932 | Step motor does not move to a position decided by ECU | BR–137 26 | BE3932 | Sub–throttle valve does not move even when the sub–throttle valve is controlled to fully open position by ECU | BR–137 31 | BE3933 | Right front wheel speed sensor signal malfunction | BR–138 32 | BE3933 | Left front wheel speed sensor signal malfunction | BR–138 33 | BE3933 | Right rear wheel speed sensor signal malfunction | BR–138 34 | BE3933 | Left rear wheel speed sensor signal malfunction | BR–138 41 | BE3934 | Low battery positive voltage or abnormally high battery positive voltage | BR–142 43*1 | BE3934 | Malfunction in ABS or TRAC (BRAKE) control system | BR–145 44 | BE3934 | Open or short in NE signal circuit | BR–147 45 | BE3934 | Main throttle position sensor circuit malfunction | BR–149 46*2 | BE3934 | Open or short in main throttle position sensor circuit | BR–149 47 | BE3934 | Sub–throttle position sensor circuit malfunction | BR–152 48 | BE3934 | Open or short in sub–throttle position sensor circuit | BR–152 51*3 | BE3935 | Engine & ECT system malfunction | BR–155 53*4 | BE3935 | ECM communication circuit malfunction | BR–156 61 | BE3936 | ABS & TRAC ECU communication circuit malfunction | BR–157 Always ON | | Malfunction in TRAC ECU | — *1: If a malfunction is detected in ABS the TRAC OFF indicator light lights up instead of the TRAC indicator light. *2: The TRAC indicator light does not light up even if an error is detected *3: If a malfunction is detected, the TRAC OFF indicator light lights up instead of the TRAC indicator light. *4: Depending on the malfunction, the TRAC indicator light does not light up.
