SRS components are located in this area. Review the SRS component locations - Refer to: SRS Component Location Index (KA/KC), or SRS Component Location Index (KA/KC) and the precautions and procedures before doing repair or service.
1. Problem verification:
Is ON indicated when you are pressing the paddle shifter + (upshift switch) and OFF with the switch released?
YES
Intermittent failure, the system is OK at this time.
NO
The failure is duplicated. Go to step 2.
2. Determine possible failure area (PCM, others):
PCM connector A (51P)
Is there continuity when pressing the paddle shifter + (upshift switch) and no continuity when the paddle shifter + (upshift switch) is released?
YES
Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom goes away and the PCM was updated, troubleshooting is complete. If the symptom goes away and the PCM was substituted, replace the original PCM.
NO
Go to step 3.
3. Determine possible failure area (paddle shifter + (upshift switch), others):
Is there continuity when pressing the paddle shifter + (upshift switch) and no continuity when the paddle shifter + (upshift switch) is released?
YES
Go to step 5.
NO
Go to step 4.
4. Paddle shifter + (upshift switch) operation check:
Paddle shifter + (upshift switch) 2P connector
Is there continuity when pressing the paddle shifter + (upshift switch) and no continuity when the paddle shifter + (upshift switch) is released?
YES
The paddle shifter + (upshift switch) is OK. Replace the cable reel subharness.
NO
Replace the paddle shifter + (upshift switch).
5. Open wire check (GND line):
Is there continuity?
YES
The GND wire is OK. Go to step 6.
NO
Repair an open in the GND wire between the cable reel and ground (G401), or repair poor ground (G401).
6. Shorted wire check (PADDLE SW UP line):
Is there continuity?
YES
Repair a short to ground in the PADDLE SW UP wire between the cable reel and the PCM.
NO
The PADDLE SW UP wire is not shorted. Go to step 7.
7. Open wire check (PADDLE SW UP line):
Is there continuity?
YES
The PADDLE SW UP wire is OK. Replace the cable reel.
NO
Repair an open in the PADDLE SW UP wire between the cable reel and the PCM.
