Trouble Code Access Using Test Equipment
- Use Self Diagnostic Checker (49 H018 9A1) and System Selector (49 B019 9A0) to retrieve trouble codes. Connect one lead of self diagnostic checker to ground and the other to system selector. Connect system selector to data link connector.
- With ignition on and engine off, verify No. 88 flashes on display and buzzer sounds for 3 seconds. If No. 88 does not flash, check main relay, power supply circuit, and connector wiring. Repair or replace as necessary. If No. 88 flashes and buzzer sounds for more than 20 seconds, check for short circuit between ECM terminal 1E and data link connector. Replace ECM as necessary and reconnect test equipment.
- Note trouble codes. Check TROUBLE CODE IDENTIFICATION chart for possible cause. If more than one code is present, codes will be displayed in numerical order. Clear codes after repairs are complete. See CLEARING CODES .
