Honda Civic. Manual — part 857

YES -Go to step 12.

NO -Check for loose terminals or poor connections at connector. If the
connections are OK, repair open or short in the wire between No. 3 (10 A) fuse
in the under-dash fuse/relay box and the reverse lockout solenoid.

12. Turn the ignition switch to LOCK (0).
13. Remove the reverse lockout solenoid (see REVERSE LOCKOUT

SOLENOID TEST ).

14. At the reverse lockout solenoid side, connect the reverse lockout solenoid 2P

connector terminal No.2 to the battery positive terminal, and connect the
terminal No. 1 to the battery negative terminal. Make sure the reverse lockout
solenoid works.

Does the reverse lockout solenoid work properly?

YES -Go to step 15.

NO -Replace the reverse lockout solenoid (see REVERSE LOCKOUT
SOLENOID TEST ).

15. Reinstall the reverse lockout solenoid, and reconnect the reverse lockout

solenoid 2P connector.

16. Jump the SCS line with the HDS.

17. Disconnect ECM connector A (44P).
18. Turn the ignition switch to ON (II).
19. Measure the voltage between ECM connector A27 and body ground.

Is there battery voltage?

YES -Check for loose terminals or poor connections at ECM connector A
(44P). If necessary, update the ECM if it does not have the latest software (see
UPDATING THE ECM ), or substitute a known-good ECM (see
SUBSTITUTING THE ECM ), then recheck. If the symptom/indication goes
away with a known-good ECM, replace the original ECM (see ECM
REPLACEMENT ).

NO -Repair open in the wire between the reverse lockout solenoid and ECM
(A27).

20. Jump the SCS line with the HDS.
21. Disconnect ECM connector A (44P).
22. Disconnect the reverse lockout solenoid 2P connector.
23. Check for continuity between the reverse lockout solenoid 2P connector

terminal No. 1 and body ground.

Is there continuity?

YES -Repair short to body ground in the wire between the reverse lockout
solenoid and the ECM (A27).

NO -Update the ECM if it does not have the latest software (see UPDATING
THE ECM ), or substitute a known-good ECM (see SUBSTITUTING THE
ECM ), then recheck. If the symptom/indication goes away with a known-good
ECM, replace the original ECM (see ECM REPLACEMENT ).

REVERSE LOCKOUT SOLENOID TEST

1. Remove the reverse lockout solenoid (see REVERSE LOCKOUT

SOLENOID TEST ).

2. Connect battery positive terminal to the reverse lockout solenoid 2P connector

No. 2 terminal, and connect the battery negative terminal to the No. 1 terminal.

3. Make sure the reverse lockout solenoid works. If the reverse lockout solenoid

does not work, replace it.

REVERSE LOCKOUT SOLENOID DISASSEMBLY/REASSEMBLY

1. Make sure you have the anti-theft code for the audio system or the navigation

system (if equipped), then write down the audio presets.

2. Disconnect the negative cable from the battery, then disconnect the positive

cable.

3. Remove the battery.
4. Remove the air cleaner assembly (see AIR CLEANER ELEMENT

INSPECTION/REPLACEMENT ).

5. Remove the battery base (see step 6 ).
6. Disconnect the output shaft (countershaft) speed sensor connector, back-up

light switch connector, and reverse lockout solenoid connector (see step 8 ).

7. Carefully remove the shift cables, and cable bracket together to avoid bending

the shift cables (see step 9 ).

8. Remove the three bolts (A) and reverse lockout solenoid (B).
