RADIO (EXCEPT JAPAN) – FAULT DIAGNOSIS

TROUBLESHOOTING HINTS

1. Check fuse F5 of Satellite Fusebox 2 (P128) and fuse F3 of Fascia Fusebox (P126). 2. Check that Radio (Z111) connectors and coaxial cable are tight and properly connected. 3. For proper Radio (Z111) noise diagnosis, take the vehicle outside where signals are strong. Close the hood and keep away from metal buildings or other sources of Radio interference. 4. If Radio (Z111) noise is excessive when an accessory is on, install a Radio noise suppression capacitor to the power lead of that accessory. 5. If Radio (Z111) noise is excessive at all times, check antenna wiring. If OK, check spark plugs, spark plug wiring and wiring close to the ignition system which could transmit noise to the Radio (Z111) wiring. 6. If only the CD Changer (Z114) does not operate, check power, ground, and DIN cable. If OK, check Radio and CD Changer. 7. If the Radio (Z111) is inoperative and ‘code’ is being shown on the display, follow the instructions below.

Security Code Instructions

1. Obtain 5-digit security code from vehicle owner or manufacturer. 2. Enter the code number using the Radio (Z111) push-button selectors. NOTE: If the correct code is not entered in 3 successive attempts, the Radio (Z111) will not accept another entry until the Radio has been left on for 1 hour with the ignition on. NOTE: When entering the code, be sure to complete the sequence numbering of that 5-digit code even if you made a mistake. For example, if the correct code number sequence is 43215 and you mistakenly enter 42 instead of 43, continue the code number sequence of 215 to complete that entry. A ‘beep’ will sound, ‘code’ will still be displayed and the Radio will not operate. Re-enter the correct code 43215 and the Radio will operate. NOTE: If an audible ‘beep’ is heard while entering the code, STOP immediately. Begin entering the code again, starting with the first number of the 5-digit code.

NOTE: If a push-button is touched accidentally when the ignition is off, a warning tone will sound. Turn the ignition on and the tone will stop.

   1. If Radio (Z111) does not operate at all, do Test A. 2. If Radio scans past all frequencies when in seek mode and hiss is present over most stations, do Test B. 3. If VF display does not dim when headlamps or park lamps are turned on, do Test C. 4. If one or more speakers do not operate, do Test D. 5. If the Subwoofer (K146) does not operate, do Test E. 6. If midrange and bass speakers do not operate on a vehicle equipped with speaker crossovers, check these speakers with Test D. If OK, replace speaker crossover.
