TROUBLESHOOTING HINTS

3. Check fuses F1, F8, F9, F14 and F15 of BeCM (Z238). 4. Check that Radio (Z111) connectors and coaxial cable are tight and properly connected. 5. 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. 6. If Radio (Z111) noise is excessive when an accessory is on, install a radio noise suppression capacitor to the power lead of the accessory. 7. If Radio (Z111) noise is excessive at all times, check antenna wiring, side screen antennas and antenna amplifiers. If OK, check speaker plugs, spark plug wiring and wiring close to the ignition system which could transmit noise to the Radio (Z111) wiring. 8. If only the CD Changer (Z114) does not operate, check DIN cable. If OK, check Radio and CD Changer (Z114). 9. If the Radio (Z111) is inoperative and displays either CODE (low line) or CODE IN (all others), follow the instructions below.

Security Code Instructions

Low Line (PRC7613) Obtain the 4 digit security code from the customer’s security card or, if they have lost it, from the manufacturer. 1. Press the preset 1 button once. 2. Using the arrow up and arrrow down buttons, change the - to show the first digit of the code. 3. Press the preset 1 once. 4. Repeat steps 2 and 3 for digits 2, 3 and 4. 5. When the preset 1 button is pressed after the fourth digit, operation should be restored. If the wrong code is entered, the word WAIT will appear. Do not switch off. Wait until CODE appears, then try again. The time delay will increase each time an incorrect code is entered. All others (PRC7617, PRC7618, AMR2672) Obtain the four digit security code from the customer’s security card or from the manufacturer. Enter the code using the preset buttons (1 to 6). When the final digit is entered, the radio should return to full operation.

If the wrong code has been entered, the display will show the number just entered, instead of the frequency. This must be cleared by pressing and holding the BAND button for 5 seconds. The display will then revert to CODE IN, and the code should be entered. If the wrong code is entered more than THREE times in succession, the code can no longer be entered. Units PRC7617 and PRC7618 will show ---. When this clears, input the correct code. Unit AMR2672 will allow the code to be entered, but will not respond even if the code is correct. If this happens, leave the set switched on for at least one hour without touching any controls. After waiting this time period, try again.
