INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (STOP)





(a) Remove the STOP fuse from the main body ECU.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:





(c) Reinstall the STOP fuse.
NG -- REPLACE FUSE
OK -- Continue to next step.
2. INSPECT BULB (REAR STOP LIGHT BULB)





(a) Remove the rear combination light assembly.
(b) Remove the high mounted stop light assembly.
(c) Apply battery voltage to the terminals and check that the rear stop light and high mounted stop light illuminates.
OK:
Rear Stop Light






High Mounted Stop Light






(d) Reinstall the rear combination light assembly.
(e) Reinstall the high mounted stop light assembly.
Result:






C -- REPLACE BULB
B -- REPLACE BULB
A -- Continue to next step.
3. INSPECT STOP LIGHT SWITCH





(a) Remove the stop light switch.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:





(c) Reinstall the stop light switch.
NG -- REPLACE STOP LIGHT SWITCH
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (STOP FUSE - STOP LIGHT SWITCH)





(a) Disconnect the A1 stop light switch connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:





(c) Reconnect the stop light switch connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (STOP LIGHT SWITCH - REAR STOP LIGHT)





(a) Disconnect the A1 stop light switch connector.
(b) Disconnect the H5 and H6 rear combination light assembly connectors.
(c) Disconnect the K1 high mounted stop light assembly connector.
(d) Measure the resistance according to the value(s) in the table below.
Standard resistance:





(e) Reconnect the stop light switch connector.
(f) Reconnect the rear combination light assembly connectors.
(g) Reconnect the high mounted stop light assembly connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (REAR STOP LIGHT - BODY GROUND)
