12. Disconnect PCM connector B (44P).

13. Connect cable reel 20P connector terminal No. 16

and body ground with a jumper wire.

14. Check for continuity between PCM connector

terminal B16 and body ground.

Check for poor connections or loose

terminals between cable reel 20P connector
terminal No. 16 and PCM connector terminal B16. If
the connection is OK, update the PCM if it does not
have the latest software (see page 11-227), or
substitute a known-good PCM (see page 11-7), then
recheck. If the symptom goes away with a known-
good PCM, replace the original PCM (see page
11-228).

SRS components are located in this area. Review the
SRS component locations (see page 24-11) and the
precautions and procedures (see page 24-13) before
doing repair or service.

1. Remove the steering wheel (see page 17-6).

2. Check for continuity between cable reel subharness

20P connector terminals No. 7 and No. 17 when
pressing the paddle shifter

(downshift switch)

and when the switch is released.

Go to step 5.

Go to step 3.

3. Disconnect the paddle shifter

(downshift switch)

connector.

4. Check for continuity between the paddle shifter

(downshift switch) connector terminals when
pressing the switch and when the switch is
released.

Replace the steering switch harness

(see page 17-7).

Replace the paddle shifter

(downshift

switch) (see page 14-277).

5. Remove the cable reel (see page 24-200).

6. Check for continuity between cable reel 20P

connector terminal No. 6 and body ground.

Go to step 7.

Repair open in the wire between cable reel

20P connector terminal No. 6 and body ground
(G504), or repair poor body ground (G504).
