Adjust the installation position of the stop light switch. Stop Light Switch > INSTALLATION">
2.CHECK STOP LIGHT SWITCH.
1) Turn the ignition switch to OFF.
2) Disconnect the stop light switch connector.
3) Measure the resistance of stop light switch terminals.
Terminals
No. 3 — No. 4:
Is the resistance less than 1 ? when the stop light switch is ON (when pedal is depressed)?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C0054 BLS OFF MALFUNCTION">Go to Step 3.
Replace the stop light switch. Stop Light Switch">
3.CHECK STOP LIGHT RELAY.
Measure the resistance of stop light relay terminals.
Terminals
No. 7 — No. 10:
Is the resistance less than 1 ??
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C0054 BLS OFF MALFUNCTION">Go to Step 4.
Replace the stop light relay.
4.CHECK VDCCM&H/U CONNECTOR.
Disconnect the connector from the VDCCM&H/U.
Is there poor contact or damage of the VDCCM&H/U connector?
Repair the VDCCM&H/U connector.
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C0054 BLS OFF MALFUNCTION">Go to Step 5.
5.CHECK STOP LIGHT SWITCH CIRCUIT.
Measure the resistance of stop light switch circuit.
Connector & terminal
(B310) No. 16 — (B567) No. 10:
(B65) No. 4 — (B567) No. 7:
(B65) No. 3 — (F/B fuse) No. 8:
Is the resistance less than 1 ??
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C0054 BLS OFF MALFUNCTION">Go to Step 6.
Repair the stop light switch circuit.
6.CHECK STOP LIGHT SWITCH CIRCUIT.
1) Connect all connectors.
2) Turn the ignition switch to ON.
3) Measure the voltage between stop light relay and chassis ground.
Connector & terminal
(B567) No. 10 (+) — Chassis ground (−):
Is the voltage 10 V or more when the stop light switch is ON (when pedal is depressed)?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C0054 BLS OFF MALFUNCTION">Go to Step 7.
Repair the stop light switch circuit.
7.CHECK VDCCM&H/U.
1) Perform the Clear Memory Mode. Clear Memory Mode">
2) Perform the Inspection Mode. Inspection Mode">
3) Read the DTC. Read Diagnostic Trouble Code (DTC)">
Is the same DTC displayed?
Replace the VDCCM&H/U. VDC Control Module and Hydraulic Control Unit (VDCCM&H/U)">
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C0054 BLS OFF MALFUNCTION">Go to Step 8.
8.CHECK DETECTION OF OTHER DTCS FOR VDC.
Read Diagnostic Trouble Code (DTC)">
Is any other DTC displayed?
Perform the diagnosis according to DTC. List of Diagnostic Trouble Code (DTC)">
Currently, it is normal. There may have been a temporary poor contact in the harness and connector or a temporary noise interference.
