CONSULT-III Reference ValueNCS00080
Diagnostic ProcedureNCS00081
1. CHECK CAN COMMUNICATION LINE
Perform self-diagnosis. Refer to AT- 8 6 , "
SELF-DIAGNOSTIC RESULT MODE" , AT- 9 2 , "TCM SELF-DIAG-
NOSTIC PROCEDURE (NO TOOLS)" .
Is a malfunction in the CAN communication indicated in the results?
YES >> Check CAN communication line. Refer to AT- 9 4 , "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK STOP LAMP SWITCH CIRCUIT
With CONSULT-III
1. Turn ignition switch ON.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Read out ON/OFF switching action of the “BRAKE SW”.

KEY INTERLOCK CABLEPFP:34908
ComponentsNCS00090
CAUTION:

Install key interlock cable in such a way that it will not be damaged by sharp bends, twists or inter-
ference with adjacent parts.

After installing key interlock cable to control device, make sure that casing cap and bracket are
firmly secured in their positions. If casing cap be removed with an external load of less than 39.2 N
(4.0 kg, 8.8 lb), replace key interlock cable with new one.
