Function (BCM - REAR DEFOGGER) 17, bCM : CONSULT-III Function (BCM - BCM)25, iMMU : CONSULT-III Function (BCM - IMMU)25, tRUNK : CONSULT-III Function (BCM - TRUNK) 26.
THEFT ALM : CONSULT-III Function (BCM THEFT ALM)27, rETAINED PWR : CONSULT-III Function (BCM RETAINED PWR)27, sIGNAL BUFFER : CONSULT-III Function 27, aIR PRESSURE MONITOR : Diagnosis Description 27.
AIR PRESSURE MONITOR : CONSULT-III Function 29, fUSE, FUSIBLE LINK : CONSULT-III Function 30, pOWER SUPPLY AND GROUND CIRCUIT 36, get the detailed information from the customer about the symptom (the condition environment when.
Record DTC freeze frame data, study the relationship between the cause detected by DTC and the symptom described by customer, is any symptom described any DTC detected, symptom is described, DTC displayed>>GO TO 3.
Symptom is described, DTC is not displayed>>GO TO 4, symptom is not described, DTC displayed>>GO TO 5, confirm the symptom described by customer, connect CONSULT-III to the vehicle in DATA MONITOR” mode and check real time diagnosis results.
Verify relation between the symptom and the condition when symptom detected, connect CONSULT-III to the vehicle in DATA MONITOR ” mode and check real time diagnosis results, perform DTC Confirmation Procedure for the displayed DTC, and then check that DTC detected again, at this time, always connect CONSULT-III to the vehicle, and check diagnostic results real time.
If two or more DTCs are detected, refer to BCS-83, "DTC Inspection Priority Chart" determine trouble, freeze frame data is useful if the DTC not detected, perform Component Function Check if DTC Confirmation Procedure is not included Service Manual, simplified check procedure is an effective alternative though DTC cannot be detected during check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC Confirmation Procedure, detect malfunctioning system according to BCS-6, "System Description" based on confirmed symptom, step and determine the trouble diagnosis order based on possible causes symptom, inspect according to Diagnostic Procedure system.
The Diagnostic Procedure described based on open circuit inspection, required for the circuit check Diagnostic Procedure, >> Check voltage of related BCM terminals using CONSULT-III, repair or replace malfunctioning part.
Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair replacement, when DTC was detected in step 2, perform DTC Confirmation Procedure Component Function Check, again, and then check that the malfunction have been repaired securely, when symptom was described from the customer, refer to confirmed symptom in step 3 or 4, check that.
YES (DTC detected)>>GO TO 8, bCM (body control module) controls the various electrical components, the control from CAN communication and the signal received from each switch sensor, bCM has combination switch reading function for reading the operation status combination switches (light.
Turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical components, bCM is equipped with the diagnosis function that performs the diagnosis with CONSULT-III various settings, in CAN communication, control units are connected with 2 communication lines (CAN-L, CAN-H) allowing, high rate of information transmission with less wiring.
Refer to the LAN-25, "CAN Communication Signal Chart", turn signal and hazard warning lamp system, interior room lamp battery saver system.
