DTC 69

DTC 69.:

DTC 69.:

CIRCUIT DESCRIPTION
When the Powertrain Control Module (PCM) detects that A/C has been requested, the PCM will activate the A/C clutch relay. When the relay has been activated, voltage should be present at both the A/C compressor clutch and the A/C clutch status line terminal of the PCM.

An open or short to ground at any point in CKT 59 will cause DTC 69 to set.

DTC 69 WILL SET WHEN:
The PCM has commanded A/C "ON" and no voltage is detected on the A/C status line for more than 25 seconds.

ACTION TAKEN (PCM will default to):
DTC 69 will be stored in the PCM memory but will not turn "ON" the Malfunction Indicator Lamp (MIL), A/C operation will be disabled.

DTC CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.

1. A problem that may prevent the compressor from engaging may or may not cause DTC 69 to set.
2. Tech 1 (or equivalent) Scanner will enable clutch circuit for 5 seconds.
3. If the A/C clutch operates properly and the Tech 1 (or equivalent Scan tool) shows A/C clutch status "OFF," then an open exists between the PCM and the splice to the compressor.

DIAGNOSTIC AIDS
Inspect the harness and all related connectors including the PCM connections. These may cause an intermittent. Check for damaged or pushed out terminals.
