Diagnostic Notes

Fig. 23 System checker harness terminal identification:





Circuit testing requires the use of a system checker harness No. 07999-PD60000A, Fig. 23. On 1988 Accord and Prelude, first check for presence of a code 14 and, if code 14 is present, refer to ``PGM-FI Troubleshooting Using Codes.''

NOTE: If the checker harness is not available, carefully back-probe the terminal harness
