DTC P1460: A/C Clutch Relay (A/CCR) Primary Circuit Malfunction (Also Referred To As WAC Circuit)
WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2006 Mercury Mountaineer, 2006 Mercury Monterey, 2006 Mercury Montego, 2006 Mercury Mariner, and 2006 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
P1460 - A/C CLUTCH RELAY (A/CCR) PRIMARY CIRCUIT MALFUNCTION (ALSO REFERRED TO AS WAC CIRCUIT)
| Description: | Monitors the A/CCR circuit output from the powertrain control module (PCM). The test fails when the PCM grounds the A/CCR circuit, excessive current draw is detected on the A/CCR circuit; or, with the A/CCR circuit not grounded by the PCM, voltage is not detected on the A/CCR circuit (the PCM expects to detect VPWR voltage coming through the A/CCR relay coil to the A/CCR circuit). | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | The A/CCR control circuit can be monitored using the WACF and WAC PID. When the WACF PID reads YES, a concern is present. An open circuit or short to ground can only be detected when the PCM is not grounding the circuit. A short to voltage can only be detected when the PCM is grounding the circuit. During the KOEO and KOER self-test, the WAC circuit is cycled on and off. Verify the A/C and the defrost were off during key on engine off (KOEO) and key on engine running (KOER) self-test (Check A/CCS the PID to verify). If the vehicle is not equipped with A/C, DTC P1460 can be ignored. |
