CIRCUIT DESCRIPTION

The IPC samples the steering wheel switch positions through an A/D converter, which converts the switch resistance to between 0 and 255 counts. Each steering wheel control switch has a unique resistance. These resistance values may be measured by disconnecting C202 and placing an ohmmeter across connector C202 terminals "A1" and "A4", then closing the switch being tested. The keys are labeled according to installed options. If a cellular telephone is installed, the labels are correct as stated. If no cellular telephone is installed, the keys will have different labels. The switch resistance and position remain the same, only the function changes with options.

DTC IP 2511 sets if a Radio control key is stuck for 5 seconds.

TROUBLESHOOTING HINTS

Check for binding, sticking or broken steering wheel touch controls. If OK, clear DTC. Check operation of steering wheel controls. If DTC again sets, replace steering wheel control switches.
