CONSULT-II Reference ValueNCS001PT
Diagnostic ProcedureNCS001PU
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis. Refer to AT- 9 2 , "
SELF-DIAGNOSTIC RESULT MODE" , AT- 1 0 3 , "Diagnostic Pro-
cedure without CONSULT-II" .
Is a malfunction in the CAN communication indicated in the results?
YES >> Check CAN communication line. Refer to AT-105, "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK STOP LAMP SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out ON/OFF switching action of the “BRAKE SW”.
OK or NG
OK >>INSPECTION END
NG >> GO TO 3.
3. CHECK STOP LAMP SWITCH
Check continuity between stop lamp switch harness connector termi-
nals. Refer to AT-187, "
Wiring Diagram — AT — NONDTC" .
Check stop lamp switch after adjusting brake pedal — refer to
BR-6, "
BRAKE PEDAL" .
OK or NG
OK >> Check the following. If NG, repair or replace damaged
parts.
Harness for short or open between battery and stop lamp switch.
Harness for short or open between stop lamp switch and unified meter and A/C amp.
10A fuse (No.20, located in fuse block).
