Back-Up Light Circuit
LIGHTING: LIGHTING SYSTEM: Back-up Light Circuit
- Back-up Light Circuit
DESCRIPTION
A/T models: The park / neutral position switch turns on when the shift lever is moved into the R position, causing the back-up light to illuminate.
M/T models: The back-up light switch turns on when the shift lever is moved into the R position, causing the back-up light to illuminate.

INSPECTION PROCEDURE
PROCEDURE
1. INSPECT FUSE (GAUGE)
(a) Remove the GAUGE fuse from the main body ECU.
(b) Measure the resistance.
Standard resistance:
Below 1 Ohms
(c) Reinstall the GAUGE fuse.
NG -- REPLACE FUSE
OK -- Continue to next step.
2. INSPECT BULB (BACK-UP LIGHT BULB)
(a) Hatchback:
(1) Remove the rear combination light assembly.
(2) Apply battery voltage to the terminals and check that the back-up light illuminates.
Standard:
(3) Reinstall the rear combination light assembly.
(b) Sedan:
(1) Remove the rear combination light assembly.
(2) Apply battery voltage to the terminals and check that the back-up light illuminates.
Standard:
(c) Reinstall the back-up light bulbs.
NG -- REPLACE BULB
OK -- Continue to next step.
3. CHECK TRANSAXLE TYPE
(a) Check the vehicle's transaxle type.
Result:
B -- INSPECT BACK-UP LIGHT SWITCH
A -- Continue to next step.
4. INSPECT PARK / NEUTRAL POSITION SWITCH
(a) Disconnect the C27 park / neutral position switch connector.
(b) Measure the resistance.
Standard resistance:
(c) Reconnect the park / neutral position switch connector.
NG -- REPLACE PARK / NEUTRAL POSITION SWITCH
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (FUSE - PARK / NEUTRAL POSITION SWITCH)
(a) Disconnect the C27 park / neutral position switch connector.
(b) Measure the voltage.
Standard voltage:
(c) Reconnect the park / neutral position switch connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (PARK / NEUTRAL POSITION SWITCH - REAR BACK-UP LIGHT)
(a) Hatchback:
(1) Disconnect the C27 park / neutral position switch connector.
(2) Disconnect the J3 and J4 rear combination light assembly connectors.
(3) Measure the resistance.
Standard resistance:
(4) Reconnect the park / neutral position switch connector.
(5) Reconnect the rear combination light assembly connectors.
(b) Sedan:
(1) Disconnect the C27 park / neutral position switch connector.
(2) Disconnect the J34 and J35 rear combination light assembly connectors.
(3) Measure the resistance.
Standard resistance:
(4) Reconnect the park / neutral position switch connector.
(5) Reconnect the rear combination light assembly connectors.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (BACK-UP LIGHT - BODY GROUND)
7. INSPECT BACK-UP LIGHT SWITCH
(a) Disconnect the back-up light switch connector.
(b) Measure the resistance.
Standard resistance:
(c) Reconnect the back-up light switch connector.
NG -- REPLACE BACK-UP LIGHT SWITCH
OK -- Continue to next step.
8. CHECK HARNESS AND CONNECTOR (FUSE - BACK-UP LIGHT SWITCH)
(a) Disconnect the C22 back-up light switch connector.
(b) Measure the voltage.
Standard voltage:
(c) Reconnect the back-up light switch connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
9. CHECK HARNESS AND CONNECTOR (BACK-UP LIGHT SWITCH - BACK-UP LIGHT)
(a) Hatchback:
(1) Disconnect the C22 back-up light switch connector.
(2) Disconnect the J3 and J4 rear combination light assembly connectors.
(3) Measure the resistance.
Standard resistance:
(4) Reconnect the back-up light switch connector.
(5) Reconnect the rear combination light assembly connectors.
(b) Sedan:
(1) Disconnect the C22 back-up light switch connector.
(2) Disconnect the J34 and J35 rear combination light assembly connectors.
(3) Measure the resistance.
Standard resistance:
(4) Reconnect the back-up light switch connector.
(5) Reconnect the rear combination light assembly connectors.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (BACK-UP LIGHT - BODY GROUND)
