Displaying Fault Codes
- Attach Diagnostic Readout Box (C-4805) to diagnostic connector, which is located near right front strut tower. Set read/hold switch in "READ" position. If diagnostic readout box is not available, flashing of power loss lamp may be used to read fault codes.
- If possible, start engine. Move A/T selector lever through all positions, ending in Park. If equipped, turn A/C on, then off. Turn engine off. DO NOT restart engine. Turn ignition on, off, on, off and on, completing sequence in 5 seconds. Record all fault codes as displayed by diagnostic readout box.
- If using power loss lamp for display, use same sequence to initiate display. Power loss lamp will first light up for 2 seconds to check bulb. After bulb check, power loss lamp will display fault codes by series of flashes.
- There are short pauses between flashes and longer pauses between digits, with 4 second pause between codes. For example, fault code 23 would be displayed by flash, flash, pause, flash, flash, flash. After 4 second pause, next numerically higher fault code will be displayed.
