Paddle Shifter Illumination Circuit

Paddle Shifter Illumination Circuit Troubleshooting 

SRS components are located in this area. Review the SRS component locations - Refer to:

SRS Component Location Index (2016) or

Component Location Index (2017 2018 2019 2020 2021) and the

Precautions and Procedures before doing repairs or service.

NOTE:  Information marked with asterisk 1 (*1) applies to the paddle shifter + (upshift switch) circuit, and with asterisk 2 (*2) applies to the paddle shifter - (downshift switch) circuit.

1. Paddle shifter check

   -1. Remove the Driver's Airbag - Removal and Installation

   - 2. Disconnect the following connector.

   Paddle shifter + (upshift switch) 4P connector*1

   Paddle shifter - (downshift switch) 4P connector*2

   - 3. Test the paddle shifter. Paddle Shifter Test (9-Speed A/T)

   Is the paddle shifter OK?

   YES 

   The Paddle Shifter is OK. Go to step 2.

   NO 

   Replace the Paddle Shifter Removal and Installation (9-Speed A/T) .

2. Fuse check

   -1. Check the following fuse

   Fuse	No. C25 (15A)
   Location	Under-dash fuse/relay box

   Is the fuse OK?

   YES 

   Go to step 3.

   NO 

   Replace the No. C25 (15 A) fuse, and recheck. If the fuse blows again, repair a short to ground in the No. C25 (15 A) fuse circuit.

3. Open wire check (ILLUMI+/ILLUMI+(B) circuit)

   -1. Disconnect the following connector.

   Under-dash fuse/relay box R (16P) connector

   - 2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF mode
   	Paddle shifter + (upshift switch) 4P connector*1: disconnected
   	Paddle shifter - (downshift switch) 4P connector*2: disconnected
   	Under-dash fuse/relay box R (16P) connector: disconnected
   Test point 1	Paddle shifter + (upshift switch) 4P connector No. 4*1
   	Paddle shifter - (downshift switch) 4P connector No. 4*2
   Test point 2	Under-dash fuse/relay box R (16P) connector No. 15

   Is there continuity?

   YES 

   The ILLUMI+/ILLUMI+(B) circuit is OK. Go to step 4.

   NO 

   Check the audio remote switch, the cruise control combination switch and the cable reel. If switches and the cable reel are OK, repair an open in the ILLUMI+/ILLUMI+(B) wire between the paddle shifter + (upshift switch)*1/paddle shifter - (downshift switch)*2 and the No.C25 (15A) fuse in the under-dash fuse/relay box.

4. Open wire check (ILLUMI-/ILLUMI-(B)/ILL-(LED)/ILLUMI-(BULB) line)

   -1. Disconnect the following connector.

   Gauge control module 32P connector

   - 2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Paddle shifter + (upshift switch) 4P connector*1: disconnected
   	Paddle shifter - (downshift switch) 4P connector*2: disconnected
   	Gauge control module 32P connector: disconnected
   Test point 1	Paddle shifter + (upshift switch) 4P connector No. 3*1
   	Paddle shifter - (downshift switch) 4P connector No. 3*2
   Test point 2	Gauge control module 32P connector No. 16 - Go to: Gauge Control Module Connector for Inputs and Outputs,

   Is there continuity?

   YES 

   The ILLUMI-/ILLUMI-(B)/ILL-(LED)/ILLUMI-(BULB) circuit is OK. Go to the Gauge Control Module Input Test .

   NO 

   Check the audio remote switch, the cruise control combination switch and the cable reel. If switches and the cable reel are OK, repair an open in the ILLUMI-/ILLUMI-(B)/ILL-(LED)/ILLUMI-(BULB) wire between the paddle shifter + (upshift switch)*1/paddle shifter - (downshift switch)*2 and the gauge control module.
