neclor:Make sure the special tool (SCS
Service Connector) is not connected to the service check connector.
Disconnecl the special lool lromtha service check connoctor andrecheck.
ls the special tool (SCS ServiceConnector) connected to the ser_vice check connector?
check the E or E Indicator
Ught:Shift to E or E position.
Check for loo3e t6lminal tit in thePCM connectors. lf necessary.substitute a known-good PCMand recheck.
Does the E or P indica-tor light come on?
Check the Gtound Circuil:1. Turn the ignition switch OFF.2. Disconnect the B (25P) con-nector from the PCM.3. Check for continuitY betweenthe 820 terminal and bodyground, and between the 822
terminal and body ground.
Repair open in the wires betweenthe 820 and 822 terminals andground {G1011, and r€Pair Poorground (G101).

Measure Power Supply CircuitVoltage:1. Turn the ignition switch ON 1ll).2. Measure the voltage betweenterminals B1 and 822 andbetween terminals Bg and 820.
Repair open or short in tho wi.ebetween the 81 and/or Bg tormi-nals and the PGM-FI main r€lay,.nd between tho PGM-FI mainrelay and the under-hood tuse/relay box.

Troubleshooting
Symptom Ghart
For electrical malfunctions which are indicated by the self-diagnostic system, reter to selt-diagnosjs function (see next
page).
Note these items before troubleshooting a symptom.
. Check the engine coolant level, and allow the engine to warm up before troubleshooting.
. Anv abnormality must be corrected before continuing the test.
. Because of the precise measurements needed, use a digital multimeter with an output of 1 mA or less at the 20 kO
range when testing.
. Before performing any troubleshooting procedures check:
- Fuses No. 47 17.5 AJ, No. 55 (40 A), No. 56 (20 A), No. 57 (20 A) in the under-hood fuse/relay box, and No. 17 {7.5 A) in
the under-dash fuse/relay box.._ Grounds No. G101, G201, G202, G401, G4O2
- Cleanliness and tightness of all connectors
SymptomSse pags
Mode control motor does not run, or one or more modes are inoperative.
Recirculation control door does not change between Fresh and Recirculate.22-24
Radiator fan does not run at all (but condenser fan runs with the AVC on).
Condenser fan does not run at all {but radiator fan runs with the Ay'C on).22-29
Both fans (radiator and condenser) do not run for engine cooling. but they both run with the A,/C
on.
Both fans do not run with the Ay'C on22-33
Compressor clutch does not engage.22-34
AJC svstem does not come on (both fans and compressor).22-37
